Prof. M. Ravindran in conversation with Prof. V.G. Idichandy

00:00:04

Professor Ravindran, I was trying to do some research

00:00:08

on your work that has been done during your career.

00:00:14

I have seen ... 4 different stages.

00:00:18

[Prof. Ravindran] Mm. [Prof. Idichandy] Probably, we will restrict the interview to these 4 stages

00:00:24

and it is probably for everybody who has done as much work as you

00:00:31

we have much more stages

00:00:33

but that we will see later on whether it can be added.

00:00:36

First one is of course, your childhood, schooling

00:00:41

and you studied in PSG College.

00:00:44

[Prof. Ravindran] Yes. [Prof. Idichandy] So, the first stage is up to completion of undergraduate

00:00:48

[Prof. Ravindran] Yes, yes. [Prof. Idichandy] in Mechanical Engineering in PSG.

00:00:53

Second stage though there is some employment in between,

00:00:58

but you came to IIT as a Technical Teacher Trainee.

00:01:03

[Prof. Ravindran] Yes. [Prof. Idichandy] And then you joined the faculty,

00:01:09

worked in Turbomachines Laboratory.

00:01:13

And ... I know fully well that

00:01:16

you're - your heart is more in the Turbo Machine Laboratory

00:01:20

wherein you know you have developed a lot of

00:01:23

experimental set up. So, that is the second stage.

00:01:26

Of course, in between you went to Germany

00:01:28

there also you had...you know,

00:01:31

made use of whatever is possible in Germany to ...

00:01:33

[Prof. Ravindran] Yes. [Prof. Idichandy] you know, get your Ph.D. done, back here in India.

00:01:38

So, that will be the second stage.

00:01:42

The third stage is, you know, Ocean Engineering,

00:01:46

because the Director has identified you as, you know,

00:01:51

faculty for Ocean Engineering to - to cut a lot of work ...

00:01:59

in establishing the department experimental facilities.

00:02:04

[Prof. Ravindran] Yes. [Prof. Idichandy] I know a little more in detail because I was also working

00:02:08

[Prof. Ravindran] Yes, yes. [Prof. Idichandy] with you at that time. So, therefore, that is the next stage.

00:02:13

Then there is a fourth stage probably

00:02:19

that is the biggest contribution that you have done

00:02:23

for the country in developing ocean technology.

00:02:26

That is the - as the Founder-Director of NIOT

00:02:30

which is an offshoot from IIT to start with,

00:02:34

but it has grown much beyond IIT

00:02:39

before you stepped down at the age of superannuation.

00:02:43

[Prof. Ravindran] Yes. [Prof. Idichandy] Later, if you add one more stage

00:02:47

it will be the stage wherein you are giving back to the society

00:02:54

and that is something which many people don’t do.

00:02:59

Those who are doing they may like to

00:03:01

pay some money and then forget about it.

00:03:03

But in your case, it is doing things

00:03:08

to make life in a very rural setting much more comfortable.

00:03:14

And your association with the - the tribal health initiative;

00:03:22

I mean these are something

00:03:24

which many of our friends should learn,

00:03:27

so that they give back to the society

00:03:29

what they have derived from it

00:03:31

and that is probably the fourth stage of your work, career.

00:03:40

Out of this, all different segments,

00:03:44

where do you - which one do you think is the most important?

00:03:49

[Prof. Ravindran] Why? [Prof. Idichandy] See, there are the [inaudible] the importance

00:03:56

it means to me personally and to the -

00:04:00

to the nations around - around the country.

00:04:03

I will [inaudible] that the contribution to the country

00:04:08

as a new development of an Institute of Ocean Technology

00:04:14

first time in our country is a contribution to the nation

00:04:18

because that has really started on a good way and if IIT and

00:04:23

we have not worked together,

00:04:24

that institute would not have come at all.

00:04:26

[Prof. Idichandy] Yes. [Prof. Ravindran] So, that was a very great effort and contribution to the nation

00:04:30

in the field of Ocean Technology.

00:04:33

The other one ... the social

00:04:37

society-related activity is giving me a great pleasure.

00:04:42

[Prof. Idichandy] Yeah. [Prof. Ravindran] Because there you see that...there are people who need of help

00:04:49

and we are able to give them some help

00:04:52

and they are extremely happy.

00:04:54

And you can see that it is useful to them, immediately.

00:04:58

So, that way I found that - that

00:05:01

these two are two different aspects, you know.

00:05:03

[Prof. Idichandy] Yeah. [Prof. Ravindran] This is a pride coming from our contribution

00:05:07

to the nation on high technology, new technology,

00:05:11

whereas, that is coming from contribution to humans.

00:05:14

From what is your capability, you are helping people and

00:05:17

and you are happy that it is useful to them.

00:05:20

So, these are two different things, at two different levels,

00:05:23

but both of things I - I give really good-

00:05:27

[Prof. Idichandy] Equal importance, ok. [Prof. Ravindran] - equal weightage to both of them.

00:05:29

[Prof. Idichandy] Yeah. I always look upon you as an institution builder.

00:05:34

It is not only in IIT,

00:05:38

wherein in Ocean Engineering Department

00:05:41

from practically nothing it has come to a stage

00:05:43

wherein it is one of the best laboratories in the country

00:05:46

and perhaps in South-East Asia

00:05:49

and NIOT - of course, there is no question.

00:05:53

I mean, I - I - I know that - that is, your heart was in that

00:05:57

almost nearly 10 years as Founder-Director

00:06:00

I think from practically nothing - a piece of paper

00:06:05

[Prof. Ravindran] Yes. [Prof. Idichandy] wherein MoU is written between IIT and DoD

00:06:09

to what you see in Pallikaranai right now is because of your planning,

00:06:15

and that way I think you can be

00:06:17

very very proud of as an institution builder.

00:06:20

[Prof. Ravindran] Yeah. [Prof. Idichandy] And of course, to the society what you are

00:06:22

[Prof. Ravindran] Yes. [Prof. Idichandy] giving back is something that is

00:06:25

[Prof. Idichandy] probably - [Prof. Ravindran] That came - that - by accidently - I didn’t plan for it

00:06:29

[Prof. Idichandy] Ok. [Prof. Ravindran] I didn’t want it.

00:06:31

Actually it came out of the interest of the IIT

00:06:35

[Prof. Idichandy] Ok. [Prof. Ravindran] to help the government to build this institution.

00:06:38

So, I mean the government

00:06:41

made a request to the then Director, IIT Madras,

00:06:43

[Prof. Idichandy] Yes. [Prof. Ravindran] and through the Dean, Professor Raju.

00:06:46

So, they said yes.

00:06:48

If at all somebody could develop this institute

00:06:50

only IIT Madras could initiate this;

00:06:53

we will provide the initial infrastructure, administrative support.

00:06:57

[Prof. Idichandy] Ok. [Prof. Ravindran] And they said, we need somebody to lead it.

00:07:02

We will also give you a person to lead it,

00:07:04

without even telling me they proposed my name.

00:07:07

[Prof. Idichandy] Now, that is the type of confidence the IIT system had in [Prof. Ravindran] So.

00:07:10

[Prof. Idichandy] Professor Ravindran's time. [Prof. Ravindran] I wore this tag only to the institute, IIT.

00:07:14

[Prof. Idichandy] And - and you have also proven the confidence that has been, you kow

00:07:17

put on you, ok.

00:07:19

[Prof. Idichandy] Let us go back to the stage one: [Prof. Ravindran] Yes.

00:07:21

[Prof. Idichandy] the childhood, your schooling [Prof. Ravindran] Yes.

00:07:24

[Prof. Idichandy] and upto BE, Mechanical Engineering [Prof. Ravindran] Yes.

00:07:28

[Prof. Idichandy] in PSG. [Prof. Ravindran] Yes.

00:07:30

[Prof. Idichandy] Briefly you can touch upon -

00:07:31

[Prof. Idichandy] it is more a biographical thing. [Prof. Ravindran] Yes.

00:07:33

[Prof. Idichandy] Yeah. [Prof. Ravindran] I came from a very small family

00:07:37

and my father was an accountant.

00:07:40

I studied in a school which was totally free in Virudhunagar

00:07:45

and I studied the pre-university also in a college

00:07:50

which is, you know, this thing.

00:07:52

And I had good academic record.

00:07:55

But ... my father was [inaudible] and he was sick that time,

00:08:01

and then he said "Okay, if you want to study Engineering

00:08:05

you put only one application,

00:08:07

[Prof. V. G. Idichandy laughs] if you get one admission at that time, you know,

00:08:11

go, otherwise we'll do some work here".

00:08:14

So, I applied and I got admission to B.Tech.

00:08:17

That's how I started my career.

00:08:20

Then, there also I involved myself

00:08:25

in learning the subject much better

00:08:28

and did lot of hands-on work

00:08:30

even for the final year B.Tech., BE I mean,

00:08:34

we did - some of our friends together,

00:08:36

we designed a working windmill

00:08:40

at that time, developing 300 watts

00:08:42

and put in the top of our Administrative Building

00:08:44

B.Tech which was working actually.

00:08:46

So, that was first happiness -

00:08:48

we said "We could design a machine".

00:08:50

[Prof. Idichandy] This is sometime in 1966. [Prof. Ravindran]'66.

00:08:53

[Prof. Idichandy] '66. [Prof. Ravindran] So,

00:08:54

[Prof. Idichandy] Yeah. [Prof. Ravindran] that was 66.

00:08:55

[Prof. Ravindran] So, that was long time ago- [Prof. Idichandy] So, before

00:08:56

[Prof. Ravindran] we fabricated. [Prof. Idichandy] windmills were not even

00:08:58

[Prof. Ravindran] known, yeah. [Prof. Idichandy] known at that time.

00:08:59

[Prof. Ravindran] Yeah. [Prof. Idichandy] Yeah, ok.

00:09:01

[Prof. Ravindran] Actually - [Prof. Idichandy] What was the motivation to do..

00:09:03

Actually, it was a funded project by CSIR,

00:09:08

one of the faculty has taken it and he left.

00:09:12

So, the institute was under constraint to complete the project

00:09:16

and the professor requested me

00:09:18

whether we could take it up and complete.

00:09:20

And that was one of the thing;

00:09:22

and it went as a report to CSIR for completion -

00:09:25

we were very proud of that.

00:09:26

[Prof. Idichandy] And ... for example, the blade. [Prof. Ravindran] Yes.

00:09:29

[Prof. Idichandy] You know, probably there were no design,

00:09:32

[inaudible] at that time. [Prof. Ravindran] Yes, yes, yes.

00:09:34

[Prof. Idichandy] How did you - how did you - [Prof. Ravindran] Actually.

00:09:36

[Prof. Idichandy] designed? [Prof. Ravindran] That's why, you know, I was basically - somehow ...

00:09:39

I had an inbuilt interest on turbomachinery.

00:09:41

So, when this request came ... there was a Russian book

00:09:46

and I requested one of the professors, Prof. Kandaswamy.

00:09:50

I said, "Please translate that

00:09:51

because there were no other books to

00:09:53

[Prof. Idichandy] Oh my god. [Prof. Ravindran] design the windmill. So, Russians had a book.

00:09:57

I forgot the name of it, but he translated and then

00:10:00

and there was one more book Putna, I remember that.

00:10:03

So, we designed, and I told, we incorporate a new device

00:10:07

because the - there was a previous model

00:10:10

made by that faculty who left.

00:10:12

[Prof. Ravindran] The base flew off when there were strong winds. [Prof. Idichandy] Oh my god.

00:10:16

[Prof. Ravindran] So, I was thinking you know

00:10:19

somehow we should have a speed limiting device.

00:10:23

[Prof. Ravindran] Something which is automatic. [Prof. Idichandy] Ok.

00:10:26

We thought about that and what we did was you know

00:10:29

we arranged the blades with the, yeah, bearing,

00:10:34

a sleeve bearing at the root, in the hub.

00:10:38

[Prof. Ravindran] So, due to the centrifugal force the blades will be moving

00:10:42

[Prof. Idichandy] Yes. [Prof. Ravindran] at a particular offset radially outwards.

00:10:45

At that time, the blades will have a pin in their axis

00:10:50

and the pin will be guided by a helical screw guide.

00:10:55

So that, as it moves out it will turn the pitch.

00:10:58

[Prof. Idichandy] Oh. [Prof. Ravindran] So, the automatically the angle of attack comes down.

00:11:02

So, the torque at high speeds automatically became less.

00:11:07

So, it was a self-regulating speed control.

00:11:10

[Prof. Idichandy] Technology is even today it is the same probably. [Prof. Ravindran] Similar, similar, yes.

00:11:14

[Prof. Ravindran] It is almost may be. [Prof. Idichandy] Yeah, now they have complicated the

00:11:17

[Prof. Ravindran] vane adjusting mechanisms, it's very expensive.

00:11:20

But on a small blade - machine like 300 watts.

00:11:24

We could afford it

00:11:25

nobody could provide such a complicated mechanism

00:11:28

of vane adjusting mechanism

00:11:30

which is similar to our turbine blades, no?

00:11:32

[Prof. Idichandy] Ok. [Prof. Ravindran] So, with this one itself, you know, it was spring-loaded.

00:11:36

See, it only works when the - the centrifugal force is too high

00:11:39

then they get back to the normals mode,

00:11:41

when the speeds are normal. So, that's what it is.

00:11:43

[Prof. Idichandy] So, it is really automatic. [Prof. Ravindran] Automatic, self-regulating.

00:11:46

[Prof. Idichandy] Ok. What about the generator?

00:11:49

[Prof. Ravindran] Generator we just bought... [Prof. Idichandy] Conversion and -

00:11:51

[Prof. Ravindran] locally - a car dynamometer, DC dynamometer: 300 watts. [Prof. Idichandy] Ok.

00:11:56

[Prof. Ravindran] So, it was a DC,

00:11:57

and it was a simply a

00:11:59

just a demonstration project that we could design

00:12:01

for a given wind speed.

00:12:03

[Prof. Ravindran] So there were some. [Prof. Idichandy] So, it like in similar projects you know

00:12:06

[Prof. Idichandy] you must have connected it to -

00:12:08

[Prof. Ravindran] Lamp load, yes. [Prof. Idichandy] Lamp load, and ...

00:12:10

[Prof. Ravindran] Lamp load. [Prof. Idichandy] And what was your feeling when the - the - the -

00:12:14

[Prof. Ravindran] It was very nice

00:12:15

and all the more happiness we got was our batch,

00:12:18

our group - 3 of us were given the Best Project Award

00:12:22

[Prof. Idichandy] Award. [Prof. Ravindran] by the faculty and we were taken

00:12:25

It was very nice. Professor

00:12:27

and Professor Subramanian, who was later Vice Chancellor of Bharathiar University.

00:12:32

He was my guide.

00:12:33

So, it was a nice feeling that something we have made works.

00:12:37

[Prof. Idichandy] Ok and - [Prof. Ravindran] Works for a long time. It is not that it will run for 2 days and stops.

00:12:42

So, that was a good feeling.

00:12:43

So, that's why when I came to IIT

00:12:45

when the Head of the Department

00:12:47

asked me which lab you want to go,

00:12:50

I said I want to go to Turbomachines Lab.

00:12:52

[Prof. Idichandy] Ok. We will come to that. [Prof. Ravindran] Yeah.

00:12:56

[Prof. Idichandy] But do you still continue your contacts with PSG, I mean some...

00:13:01

[Prof. Ravindran] Yeah, very little, but we have contact

00:13:04

but we have the Alumni Association,

00:13:06

but I am not continuing the technical contact.

00:13:09

So, I was continuing till about 5 years ago

00:13:13

because I was also the Naval Research

00:13:15

Board Chairman [inaudible]

00:13:17

and I was part of the RUTAG of IIT Madras.

00:13:20

So, in these connections, we were going for discussions

00:13:23

with them to do projects for us.

00:13:27

[Prof. Idichandy] Ok. [Prof. Ravindran] And, but they were a bit slow on that.

00:13:33

[Prof. Ravindran] So, they were not coming forward [Prof. Idichandy] Ok.

00:13:36

because they were always busy.

00:13:38

So, we lost interest in them basically, because the PhD people...

00:13:44

[Prof. Idichandy] I think, probably they have their own priorities. [Prof. Ravindran] Priorities, yes.

00:13:47

Because they were mainly concentrating on Undergraduate B.Tech.

00:13:50

[Prof. Idichandy] Yeah. [Prof. Ravindran] And the Mechanical Department was very good,

00:13:53

but they were not very keen on

00:13:55

[Prof. Ravindran] doing sponsored research funding. [Prof. Idichandy] Research funding.

00:13:58

Probably, they wanted to come out

00:14:02

[Prof. Idichandy] with larger number of graduates than... [Prof. Ravindran] Yes.

00:14:05

They are expanding that they have built one more institution,

00:14:08

they are on a - this thing,

00:14:11

expansion mode at the B.Tech. level, maybe little bit of M.Tech.,

00:14:14

but we have this alumni meetings for the last 51 years.

00:14:18

[Prof. Idichandy] Yes, yes. Every year. [Prof. Ravindran] It's still going on - every year.

00:14:21

[Prof. Idichandy] there we have and it is held only in the college itself. [Prof. Ravindran] No, not college.

00:14:25

[Prof. Idichandy] Oh, I see, different places. [Prof. Ravindran] We meet outside; except the 50th anniversary.

00:14:28

And the Silver Jubilee 25th anniversary,

00:14:30

all the other meetings are ... it's a family get-together

00:14:32

[Prof. Idichandy] Ok. [Prof. Ravindran] of classmates, it is nothing technical.

00:14:35

[Prof. Idichandy] Ok. [Prof. Ravindran] We meet, spend 2-3 days together,

00:14:38

and we are planning for a foreign trip this year,

00:14:41

next year - early next year - to Thailand.

00:14:43

[Prof. Idichandy] Oh, I see, ok. [Prof. Ravindran] 70 people are with me, 60 to 62 people, yes.

00:14:48

[Prof. Idichandy] Ok. Do you remember some of your very close friends

00:14:52

who have reached, you know, some stage

00:14:56

wherein you know, who have done very well - in - in - in - in -

00:15:02

[Prof. Ravindran] My BE? [Prof. Idichandy] contributing back ... your - your own batch.

00:15:05

Yes, yeah. There are many of them.

00:15:07

Some of the people were in BHEL Trichy,

00:15:11

they came out and started firms - consultancy firms,

00:15:15

engineering firms like Fishner and the - N. Chandrasekaran.

00:15:21

I think he became a big industrialist.

00:15:24

And in Coimbatore itself there is one Balasundaram,

00:15:29

who was in Electrical branch

00:15:30

and he is with that KG group and then

00:15:35

he is in charge of this Trigger Jeans company.

00:15:39

And he himself runs a stock broking.

00:15:43

[Prof. Ravindran] He has become a financial management man. [Prof. Idichandy] Ok.

00:15:46

And my own namesake, my roommate [inaudible]

00:15:50

they put people as per the alphabetical order.

00:15:52

So, I have another classmate named Ravindran

00:15:55

from a - that too, Mettupalayam - he is a industrialist.

00:15:58

He is making this, you know, paper - newspaper

00:16:01

actually he got in Madras, Andhra,

00:16:04

he a very successful man.

00:16:07

We have some people

00:16:08

employed in industries also: one Ranganathan,

00:16:11

who was given a President's Award,

00:16:12

he was a BAL Chief Executive, my own classmate in Bangalore.

00:16:19

[Prof. Idichandy] Ok, so - [Prof. Ravindran] Like that.

00:16:22

[Prof. Idichandy] That was perhaps, you know, after the graduation

00:16:25

probably you are always inclined to go for higher studies.

00:16:29

[Prof. Ravindran] Yes, that was my interest, actually. [Prof. Idichandy] Yeah.

00:16:31

because somehow you know when I started applying for...

00:16:36

when I started - about Engineering education

00:16:39

I came to know about -

00:16:40

I heard that IIT Madras has started, so I wanted to apply.

00:16:44

Sometime in February, March I was thinking,

00:16:47

then they said oh you fellow, you're

00:16:49

[Prof. Ravindran] too late. I never knew that we have to write an entrance exam. [Prof. Idichandy] Oh, time was over.

00:16:52

So, at that time itself I was thinking,

00:16:54

so IIT is something different, we should go.

00:16:57

But ... middle of my graduation

00:17:00

there was some compulsion from my family

00:17:02

that I should go for work.

00:17:05

So, when I saw this advertisement

00:17:07

for Technical Teacher Training Programme which was

00:17:11

Central Government's Programme, Ministry of Education,

00:17:14

to select candidates for, yeah, teaching career,

00:17:18

at that time itself, when there were

00:17:20

so few engineering colleges, they thought of

00:17:23

developing good faculty for engineering colleges.

00:17:26

So, they started this programme for providing Master’s degree

00:17:32

[Prof. Ravindran] as well as giving them training in teaching [Prof. Idichandy] Teaching.

00:17:35

in standard institution like IIT Madras and Anna University.

00:17:38

So, I applied for it. I was very really lucky to get selected.

00:17:42

So, we got almost double the scholarship compared to our M.Tech.

00:17:46

[Prof. Idichandy] Ok. [Prof. Ravindran] And we were also given an opportunity

00:17:50

to work in institution like IIT, work with German professors.

00:17:55

I think that was the greatest opportunity in my life, I thought.

00:17:58

My interest -so, I am just doing M.Tech., but this opportunity

00:18:01

to work with German professor - even short period,

00:18:05

I think that was a very great experience I could have.

00:18:09

[Prof. Idichandy] What was the year when you came to IIT Madras? [Prof. Ravindran] 1966.

00:18:12

[Prof. Idichandy] '66. [Prof. Ravindran] Immediately after graduation, I worked for 1 month

00:18:15

in a local Karaikudi Engineering College,

00:18:17

I left that, and I joined here - and that professor - that time he was

00:18:22

Professor Vijay Ram, who was later Guindy

00:18:24

[Prof. Idichandy] Oh, ok. [Prof. Ravindran] Principal, he said, "You should go to IIT".

00:18:28

He said, "You don't have to work in Karaikudi,

00:18:29

you please go to IIT.

00:18:31

So, he relieved me and then he said you go, so...

00:18:34

At that time, IIT was a great ambition in life

00:18:38

[Prof. Ravindran] you know 'we should get into IIT'. [Prof. Idichandy] Yes.

00:18:40

And then get M.Tech.

00:18:41

So, that was, so immediately came and joined here, '66.

00:18:45

[Prof. Idichandy] Ok. [Prof. Ravindran] August exactly.

00:18:50

[Prof. Idichandy] And ... probably, you know, you thought -

00:18:53

I - I - don't know whether you were always having an inclination

00:18:57

to work in the faculty of IIT

00:18:58

because after this 3 years of technical teacher-training

00:19:03

[Prof. Idichandy] you will be allotted some college by the [Prof. Ravindran] Yes.

00:19:06

[Prof. Idichandy] Government and- [Prof. Ravindran] Yes, yes.

00:19:08

But ... still you had interest in continuing in IIT in the faculty.

00:19:15

[Prof. Ravindran] It was like this. You see, the ... one of the conditions of the

00:19:19

selection for the Teacher Training Programme was that

00:19:22

we should serve at least 3 years in any engineering college

00:19:26

[Prof. Idichandy] Anywhere. [Prof. Ravindran] decided by the Ministry anywhere in India.

00:19:30

So, we had accepted that.

00:19:31

So, I had accepted the condition.

00:19:35

But I had a very lucky break, I should tell you now itself

00:19:38

because I don't know how many people had this opportunity.

00:19:41

During these 3 years, you know,

00:19:43

I was given ... very very tough task of

00:19:47

erecting certain test rig, very complicated test rigs;

00:19:51

fabrication, erection, testing by the German professor.

00:19:55

[Prof. Idichandy] This is in addition to your [Prof. Ravindran] To the

00:19:57

[Prof. Idichandy] course work. [Prof. Ravindran] yes yes, course work.

00:19:59

He said, "Your course work is your own personal benefit"

00:20:02

because that was - he was a very tough -

00:20:03

that's why not many people

00:20:05

[Prof. Ravindran] wanted to work under this Professor Scheer. [Prof. Idichandy] And [inaudible]

00:20:07

[Prof. Ravindran] I have great respect for him. [Prof. Idichandy] ... has a German attitude.

00:20:09

German. And he said, you know,

00:20:11

at that time there were many German professors

00:20:13

in IIT Madras - in Mechanical and Civil there were.

00:20:17

But what they did was

00:20:18

they brought equipments and erected them.

00:20:21

So, they could develop the laboratories fast.

00:20:25

Well, this Professor Scheer said "No, I want you guys

00:20:29

to design, fabricate, and erect and operate."

00:20:35

So, this was a very slow, painful process.

00:20:38

And it was very tough;

00:20:39

not many people wanted to do this - faculty.

00:20:42

So, the initial faculty ran away from him.

00:20:47

So, let’s say when I told you other day that

00:20:49

when Head of the Department

00:20:51

asked me where do you want to go,

00:20:52

I say I want to do Turbomachinery.

00:20:53

He said "Don't come and cry to me

00:20:55

that I ruined your career."

00:20:57

I said, "What is wrong with Turbomachines Lab?"

00:21:00

Later only, I knew that because of his very tough attitude

00:21:04

that doing work is only thing,

00:21:06

he will never give leave,

00:21:08

you have to do all the drawings yourself,

00:21:10

you go to the central workshop, get them fabricated,

00:21:12

erect, everything we had to do

00:21:14

like a very factory-level

00:21:15

which many of the initial faculty didn’t want.

00:21:18

[Prof. Idichandy] And most of it were done by you, alone? [Prof. Ravindran] No, there was a -

00:21:22

[Prof. Idichandy] Probably technical help. [Prof. Ravindran] That - that was the advantage, you know

00:21:25

the German design was that each laboratory -

00:21:28

we had at that time 10 laboratories in Mechanical Engineering -

00:21:30

had its own full quota of technical staff and equipment

00:21:35

[Prof. Ravindran] like lathe, milling machine, shaping machine. [Prof. Idichandy] Yeah yeah.

00:21:38

Small milling machine for tool making, this one;

00:21:41

drill - huge drilling, radar drilling machines.

00:21:43

So, we were well-equipped

00:21:45

to do the fabrication within ourself.

00:21:47

Whatever could not be done could be done in central workshop.

00:21:50

[Prof. Idichandy] Yeah. [Prof. Ravindran] So, most of the equipment like all the welding equipment

00:21:54

gas welding, arc welding, everything was provided to us

00:21:58

and this professor will come and supervise that

00:22:01

we are doing it correctly.

00:22:03

So, that is the best training period I ever had.

00:22:06

Then he will say, "I am going to teach Turbomachines.

00:22:09

All you guys come and attend."

00:22:11

So, me, along with Professor Venkatrayulu

00:22:14

who was at that time my batchmate,

00:22:17

we used to carry all the equipment

00:22:19

of turbomachinery models, you know,

00:22:21

to the class and he will explain,

00:22:24

I one of the best teacher in practical things.

00:22:26

So, compared to what I learnt in undergraduate,

00:22:30

I learnt more attending his lecture in IIT

00:22:34

by Professor Scheer on Turbomachines: on theory,

00:22:38

design, fabrication, and performance test.

00:22:42

Complete, it was a total course.

00:22:45

[Prof. Idichandy] Which - which university in Germany he was associated?

00:22:48

He was associated with Braunschweig.

00:22:50

[Prof. Idichandy] Braunschweig. [Prof. Ravindran] Technical University of Braunschweig.

00:22:52

And he was - he was - he was a war veteran,

00:22:56

then he has completed his Ph.D.

00:22:59

and when he came here none of [inaudible] were available,

00:23:02

so he was teaching Drawing.

00:23:04

He was also designated as Professor of Drawing.

00:23:07

So, he used to be a very meticulous instructor for drawing.

00:23:13

So, he will say: everything should have a drawing,

00:23:16

even if you make a chalk piece holder,

00:23:18

there should be a drawing.

00:23:20

So, he designed a system of designation of drawings,

00:23:23

numbering of drawings, storing them and assembling them - he got,

00:23:27

get - got his equipment to keep drawings properly.

00:23:30

All those things are still available after almost 50 years.

00:23:34

[Prof. Idichandy] Ok. [Prof. Ravindran] You can even [inaudible].

00:23:37

So, that this way, he taught us meticulously.

00:23:40

I was in charge some of the keys, you know,

00:23:42

every key in the laboratory,

00:23:43

every table key, every door key, every cupboard key

00:23:46

will have a duplicate, it will be in a central key board.

00:23:48

I was a key manager in that - key-in-charge,

00:23:50

like that, you know.

00:23:51

About everything, there was perfect discipline,

00:23:54

he taught us, yes.

00:23:56

[Prof. Idichandy] No wonder that you transfered many of these things, you know.

00:23:59

[Prof. Ravindran] So, that is the best part of my learning

00:24:02

in my life, was that 3 years

00:24:04

I went to Professor Scheer.

00:24:07

[Prof. Idichandy] Now, with Turbomachines Laboratory which you have completed

00:24:10

[Prof. Idichandy] your Master's in 3 years. [Prof. Ravindran] Yes. Yes.

00:24:15

Before I come to a very pertinent question which is

00:24:20

about the situation of laboratories

00:24:22

in - in - in IIT Madras in the present.

00:24:28

Was there any offer from the Government of India

00:24:30

for to you to go to some college after completion of it?

00:24:35

[Prof. Ravindran] That is - I was just -

00:24:37

I was about to say that, you know,

00:24:39

after I submitted my Ph.D. thesis with the

00:24:42

fabrication of test rig for the axial flow welding machine,

00:24:47

then I took an extra project title

00:24:50

of studying the inlet flow region of axial pumps.

00:24:54

So, that was also experimental, theoretical.

00:24:56

So, when I put all this work together -

00:24:58

in the 3 years of work, together -

00:25:00

it became so thick

00:25:01

and I presented the entire result to the committee,

00:25:05

Professor Thirunarayanan was the examiner,

00:25:07

[Prof. Ravindran] Head of the Department of IAC. [Prof. Idichandy] Ok.

00:25:10

In Mechanical Engineering - was the exam,

00:25:11

that - that - that was the level

00:25:12

[Prof. Ravindran] at which M.Tech. exams were held at that time. [Prof. Idichandy] Ok.

00:25:14

[Prof. Ravindran] Even though I - I don’t think we get those people in for [Prof. Idichandy] No, no.

00:25:18

[Prof. Ravindran] Ph.D.s now. He came and asked

00:25:20

"What, Ravindran, after all you are going to be -

00:25:22

after all you are going to be a teacher,

00:25:24

why have you done so much of work -

00:25:26

design, fabrication, experiments, making probes, calibrating them."

00:25:30

Then, I told - at that time, I had the offer from Calicut University

00:25:33

[Prof. Ravindran] to go, I had the offer. [Prof. Idichandy] Ok.

00:25:35

[Prof. Ravindran] I told him, "Sir,

00:25:38

any teacher should have the capability and confidence

00:25:42

to design machines, fabricate them, erect them,

00:25:46

and make them work successfully

00:25:48

for the design specification as made.

00:25:50

I have done this. I have this confidence

00:25:53

so wherever I go, I will be a good teacher

00:25:56

because I can teach the students how to

00:25:58

design, fabricate, commission, with all practical knowledge.

00:26:02

So, wherever I will go I will be a good teacher," I told him.

00:26:05

Then, the Head of the Department was present:

00:26:07

Narayan, he was Head of the YOC.

00:26:09

[Prof. Idichandy] Oh, board. [Prof. Ravindran] Board.

00:26:11

He said "He need not go anywhere,

00:26:14

myself and Venkatrayulu, my batchmate,

00:26:19

they can join us as faculty tomorrow."

00:26:22

Just like that. On the viva examination day,

00:26:25

he said they can join on ad hoc basis

00:26:28

[Prof. Ravindran] and which was at the time - Dr. Ramachandra was the director. [Prof. Idichandy] Ok.

00:26:31

He got us [inaudible] as a faculty few months later.

00:26:35

That's how I entered as a faculty, my transition from

00:26:39

teacher trainee to faculty happened in

00:26:41

'69 August - September - on the viva day.

00:26:45

I don’t think many people would have had this lucky chance

00:26:51

[Prof. Ravindran] to become a - [Prof. Idichandy] No, I do not think there will be any comparison account anywhere anytime, later also.

00:26:54

Because to get into this, you know,

00:26:55

[Prof. Ravindran] you have to go through so much of process. [Prof. Idichandy] Yeah.

00:26:57

[Prof. Ravindran] Whereas, just like that we got into IIT. [Prof. Idichandy] Ok.

00:27:01

[Prof. Idichandy] Now, you are a person who has been down to earth. [Prof. Ravindran] Yes.

00:27:05

So, you know working in the laboratory,

00:27:07

designing your own stuff,

00:27:10

getting it fabricated, I mean, totally hands-on.

00:27:15

What do you think about the present engineers?

00:27:18

I am not asking about IITs at all.

00:27:23

If you go to a typical engineering college

00:27:25

wherein, you know, graduates are produced,

00:27:29

do you think they get - they are lucky to get into

00:27:32

[Prof. Idichandy] you know, such type of an education? [Prof. Ravindran] No, not, except in few institution.

00:27:37

[Prof. Ravindran] Bulk of the present engineering students

00:27:40

do not get this opportunity.

00:27:43

One of the reason being, in the last decade has been that

00:27:46

the IT companies came and selected them,

00:27:49

and gave them some jobs

00:27:51

totally unconnected with what they study.

00:27:53

So, slowly the students lost interest in hands-on work.

00:27:56

The faculty also thought it was unnecessary to train them

00:28:00

[Prof. Ravindran] because anyway they get a job. [Prof. Idichandy] Correct.

00:28:02

[Prof. Idichandy] And that has nothing to do with what they learn. [Prof. Ravindran] Yes.

00:28:05

[Prof. Ravindran] So, sometime the offers came in the 3rd year itself,

00:28:08

so 4th year they never learned anything.

00:28:11

So, now, that's why some of the ...

00:28:13

the government rule has come that

00:28:14

you should come for campus only in the 4th year.

00:28:17

I think this is a very negative aspect

00:28:19

because, what for we train engineers,

00:28:22

they should have a problem-solving capability

00:28:26

for their own interest is around them,

00:28:30

[Prof. Ravindran] you can also do R and D. [Prof. Idichandy] Yes.

00:28:33

Excellence, then you publish, take patents,

00:28:35

that's one way of going up in your career.

00:28:38

But otherwise you are supposed to transfer your capability

00:28:42

to problem-solving practical industries,

00:28:45

[Prof. Ravindran] develop something what society needs. [Prof. Idichandy] Yeah.

00:28:47

[Prof. Idichandy] Can somebody design a machine?

00:28:50

So, that capability is totally missing.

00:28:52

So, many people ask me to come and teach,

00:28:55

I say I don’t want.

00:28:56

But one of the college now I am going I am stressing this,

00:29:00

I making them do hands-on work,

00:29:03

you know, all the few institution

00:29:05

where I am just mentoring. I am stressing,

00:29:07

but 85 percent of the students

00:29:10

who are getting undergraduate degrees,

00:29:15

they don't get this hands-on experience at all.

00:29:17

[Prof. Idichandy] Unfortunately, teachers are also not

00:29:19

very - very much inclined to take that type of offer.

00:29:22

[Prof. Ravindran] Because they have never seen an industry. [Prof. Idichandy] Yes.

00:29:25

[Prof. Ravindran] I can give you one disastrous situation.

00:29:28

I will not tell the institution.

00:29:30

I was talking to a faculty

00:29:31

who was a student of the same college.

00:29:35

It seem one student asked: "Sir" - Electrical student -

00:29:39

"Sir, I have not seen a induction motor".

00:29:42

This faculty, he said, I myself has not seen one".

00:29:46

[Prof. Ravindran] You - this is the status of the faculty. [Prof. Idichandy] Yeah.

00:29:49

[Prof. Ravindran] What good is the degree of the

00:29:52

undergraduate student studying under him?

00:29:54

So, I think it's very very important that

00:29:58

we should come back to this hands-on experience

00:30:01

by making it compulsory for the institutions

00:30:04

to work with industries

00:30:05

[Prof. Ravindran] and for students to work with industrial problems. [Prof. Idichandy] Yeah.

00:30:09

[Prof. Ravindran] That is my - that is the sad part of the Engineering education today.

00:30:14

[Prof. Idichandy] Don't you think that to some extent that has also

00:30:17

come into the IIT system, you know wherein probably

00:30:21

[Prof. Idichandy] they are little better off than the normal in various - [Prof. Ravindran] Yeah.

00:30:26

[Prof. Ravindran] My own experience - see, because

00:30:30

that was very clearly expressed by the ...

00:30:33

some of the visiting professor who came for the

00:30:36

50th anniversary of the Indo-German collaboration.

00:30:39

Some of - Professor Scheer himself was there,

00:30:42

his assistants were all there,

00:30:43

but some of the remarks were very very painful to hear.

00:30:51

Saying that the facility which they have created in the

00:30:54

late '60s, early '70s, were all

00:30:57

coming down in its quality and effectiveness,

00:31:01

and IIT Madras never took an initiative to upgrade them.

00:31:05

[Prof. Idichandy] Ok. [Prof. Ravindran] Especially, Professor Lutz was

00:31:08

almost crying. You see, his boilers and steam turbines

00:31:12

[Prof. Ravindran] have disappeared. [Prof. Idichandy] Yes.

00:31:14

And our own lab, even though some physicists are working

00:31:17

the original he brought, some turbines product,

00:31:22

they were all corroded and - this thing - they were not replaced.

00:31:26

So, and the - the - the - workshop manpower not there.

00:31:33

So, the students were very reluctant to take up

00:31:36

Master's and Ph.D. programmes in such labs.

00:31:38

[Prof. Idichandy] Yeah. [Prof. Ravindran] I think that has killed the initiative on

00:31:44

hands-on experience for the people

00:31:46

plus we did so much of work: we used to work in the lathe,

00:31:48

and the milling machine ourselves to manufacture, weld ourselves,

00:31:52

we had training in welding because number of pipelines were,

00:31:55

14 is pipeline, we used to weld for the test rigs.

00:31:58

So, that type of experience our students are not being given

00:32:03

by default, you know, because we don't have the manpower.

00:32:06

So, people are staying away, okay, if we go for equipment work,

00:32:10

I have to get all the things in -

00:32:12

fabricated outside, it is time consuming, it is expensive,

00:32:16

easy way to sit before the computer to do some modeling.

00:32:20

Easily you can publish papers, you can get your M.Tech. or Ph.D.,

00:32:24

that seems to be the trend nowadays.

00:32:26

[Prof. Idichandy] Yeah. [Prof. Ravindran] Even in IITs.

00:32:27

I am not very happy with that because that may be good for

00:32:33

getting our admissions abroad and

00:32:35

going thing but that is not expected

00:32:37

for engineer to contribute to the local industries.

00:32:42

I am very - very very particular about that

00:32:44

that IIT is not contributing enough

00:32:48

to the hands-on experience of students.

00:32:50

Even the number of those days we used to have

00:32:52

[Prof. Ravindran] workshop week completely. [Prof. Idichandy] Yeah.

00:32:55

Whole week they used to work in all the lab,

00:32:58

Workshops at Central Workshop,

00:32:59

Carpentry, Smithy, Machine Tools lab, Welding lab.

00:33:04

[Prof. Ravindran] Nowadays, that workshop also is reduced. [Prof. Idichandy] Yeah.

00:33:10

And one of the contributing factors is

00:33:12

that the 5-year programme came - became 4-year programme.

00:33:15

They expect lot of work to go into the plus 2.

00:33:17

[Prof. Idichandy] Yes. [Prof. Ravindran] But that didn’t happen.

00:33:20

We lost something in this process.

00:33:24

Engineering education lost some

00:33:26

very precious time in educating them and

00:33:28

this is because we lost 1 year of the instruction period.

00:33:32

[Prof. Idichandy] Ok. But coming to the students' point of view

00:33:35

because once, one of my

00:33:39

friend's son who joined Computer Science here,

00:33:44

he asked me: "Why should I do Workshop because in my lifetime

00:33:50

I will never even look at any of these machines

00:33:52

because it is not necessary."

00:33:55

And slowly from Computer Science the same question

00:33:58

is being asked even by Mechanical Engineers

00:34:00

you know: "Why should I do Workshop,

00:34:03

why should I dirty my hand

00:34:05

when I can get, you know, complete my courses

00:34:08

and also complete my project without -

00:34:11

[Prof. Ravindran] Yes. [Prof. Idichandy] -dirtying my hands and all."

00:34:13

That is looking ... very narrow approach to life.

00:34:17

You see, you can be a Computer Science Engineer

00:34:19

be a Computer Science man all the time,

00:34:21

look at servicing of computers

00:34:23

or develop computer language, hardware, software all that;

00:34:26

that means, your part of life is restricted

00:34:28

to a very small group of experts.

00:34:33

But in a field like Mechanical Engineering,

00:34:37

you can do computer simulations, test analysis,

00:34:40

software pactice all that you can - be -

00:34:42

do with only with computer knowledge.

00:34:43

[Prof. Ravindran] But finally, who will make - hardware?

00:34:46

[Prof. Idichandy] Yeah. [Prof. Ravindran] Somebody has to produce things,

00:34:49

things around us - who is manufacturing them,

00:34:51

who designs the machines to manufacture them,

00:34:53

who - machines the - who manufactures the tools

00:34:56

dyes, tool bits, to machine this,

00:34:59

material development, machining process,

00:35:02

finishing process - who does that?

00:35:05

He has to be a practical engineer.

00:35:08

Who developed that - interface is - totally, that's why

00:35:11

we are not making any new machines in our country.

00:35:14

[Prof. Idichandy] Yeah. [Prof. Ravindran] We buy and use them.

00:35:16

[Prof. Idichandy] Yes. [Prof. Ravindran] Are we making new machines?

00:35:19

Are we designing new machines?

00:35:20

Are we developing new technologies?

00:35:22

Are we taking new patents which are possible to be made

00:35:25

for our own industry? That is our weakness,

00:35:28

unless we improve upon this

00:35:31

physical hands-on experience for our own engineers,

00:35:36

we are going to be always a

00:35:38

second generation of machine users.

00:35:41

So, to make our Make in India

00:35:43

successful you think that the entire

00:35:46

engineering education has to be revamped.

00:35:49

Definitely. See, nowadays Make in India is import technology,

00:35:53

[Prof. Idichandy] Yeah. [Prof. Ravindran] use the factory - you are using our

00:35:55

cheap labour - that is not Make in India.

00:35:58

Make in India is really that you design,

00:36:00

make our R and D laboratories,

00:36:02

technology laboratories - you - to make mistakes and design,

00:36:06

give them time, and a chance to make mistakes and learn

00:36:10

hands-on experience, develop their own machines,

00:36:14

support them. Where do we support them -to make?

00:36:17

[Prof. Idichandy] Yeah, unfortunately that is the situation.

00:36:20

[Prof. Ravindran] Unfortunately, in Defence also,

00:36:21

the same thing is happened.

00:36:23

I have seen in Defence Laboratory,

00:36:24

you have seen in Defence Laboratories.

00:36:26

Lot of work is done, but they will never buy the final product.

00:36:30

There are some Western interest, difficulties,

00:36:34

maybe some of them are not reliable,

00:36:36

materials are not the best, but

00:36:38

we should give them a chance to improve.

00:36:41

In many case like space,

00:36:43

we have proven that we can do wonders.

00:36:46

[Prof. Idichandy] Yeah. [Prof. Ravindran] Why the same chance is not being

00:36:48

given to other industries?

00:36:51

The support that ISRO enjoys today

00:36:53

or Atomic Energy enjoys today,

00:36:56

Science and Technology Bombay is not enjoying.

00:37:00

Human Resource Department is not enjoying

00:37:04

that is why our education system is suffering.

00:37:06

Science and technology is suffering.

00:37:09

Technology development is suffering.

00:37:11

Because our education systems also fall into that trap

00:37:15

that we make people more computer-based,

00:37:17

not hardware-based at all, thanks for the [inaudible].

00:37:20

[Prof. Idichandy] See, unfortunately the - the - ultimately what happens is

00:37:23

even the faculty who are joining,

00:37:26

many of them do not have - any - any hands-on experience at all.

00:37:30

Yes. Similar thing will happen, I told you

00:37:32

one faculty said in one of the - "I have not seen induction machine".

00:37:36

Same thing will happen to some of these people.

00:37:39

High-tech Computer Science engineers or high-tech

00:37:42

Chemical engineer, he may - he may not see a

00:37:45

lathe or this thing, he may not be able to do any work.

00:37:48

So - that should not - we should not allow this

00:37:52

degradation of the practical knowledge to happen

00:37:55

in our hands-on experience

00:37:58

Yeah, let us hope that I mean your -

00:38:00

this voice will reach some stage wherein, you know, there will be some -

00:38:04

[Prof. Ravindran] That is my sadness here, that - [Prof. Idichandy] Like many [inaudible]...

00:38:06

[Prof. Ravindran] Because I started my career

00:38:07

with so much of this thing and all

00:38:09

I see before my eyes, yeah, change of trend.

00:38:15

Many people thinking that we don’t have to do this.

00:38:18

The younger generation thinks that

00:38:19

hands-on experience is not required,

00:38:21

that is my saddest feeling as a engineer,

00:38:25

as a Mechanical Engineer, or Ocean Engineer.

00:38:30

[Prof. Idichandy] Shall we stop for some time or -

00:38:33

[Mr. Kumaran Sathasivam] We - we cannot, sir. [Ms. Mamata Dash] 10 minutes,

00:38:34

[Ms. Mamata Dash] another 10 minutes. [Mr. Kumaran Sathasivam] We have another 10 minutes

00:38:36

[Mr. Kumaran Sathasivam] which we can use. [Prof. Idichandy] 10 minutes.

00:38:37

[Mr. Kumaran Sathasivam] Yes. Ok

00:38:38

[Mr. Kumaran Sathasivam] before we need to stop.

00:38:39

[Prof. Idichandy] Now, I can understand your, you know, hard feeling

00:38:42

because you have done so much to the laboratory,

00:38:47

it has been brought to a certain stage,

00:38:49

have you visited the laboratory again -

00:38:52

not before - or after that 50th Golden Jubilee here?

00:38:57

I have been visiting especially, Ocean Centre I have visited,

00:39:00

but Turbomachines Laboratory

00:39:02

I think once or twice I have gone.

00:39:04

But things are not very

00:39:10

very well because the number of faculty.

00:39:12

[Prof. Idichandy] Yeah. [Prof. Ravindran] See, for example,

00:39:14

I am attached to the Turbomachines Laboratory

00:39:16

because no institution or country

00:39:19

is teaching the turbomachines similar to what

00:39:22

the German system has introduced here.

00:39:25

Pumps, turbines, steam turbines or gas turbines,

00:39:28

they all are taught in a unified theory

00:39:33

and special fluid related properties are solved separately.

00:39:36

So, we have two groups of turbomachines.

00:39:38

And the knowledge those days

00:39:41

we used to have Turbo Machine lectures for 2 years

00:39:43

in the 5 year stream. So, a person could

00:39:48

without any knowledge of pumps or turbines earlier

00:39:52

could design the turbine, fabricate.

00:39:54

So, all of M.Tech. students those days

00:39:57

do a fabrication of a pump or a turbine and do the testing,

00:40:01

that was our standard at that time.

00:40:03

[Prof. Idichandy] Ok. [Prof. Ravindran] That - that means, when they could

00:40:05

[inaudible] what does industry need

00:40:08

the R and D department, we

00:40:10

develop engineers for R and D department.

00:40:11

So, we want him to be capable of designing a new system

00:40:16

or modify the existing impeller to a new application,

00:40:20

modify the materials to a new fluid being handled,

00:40:23

a slurry pump or a turbine.

00:40:25

So, even the faculty: Professor Prithviraj or

00:40:29

everybody was able to design hands-on things.

00:40:35

I think that - what is - is - helping

00:40:37

the development of new machines, new ideas

00:40:40

can be transformed into new hardware;

00:40:43

if you have that practical knowledge of doing that,

00:40:45

but if you are sitting before a computer

00:40:48

only, that becomes very difficult.

00:40:53

Because I - I - I forgot to tell you also that turbine

00:40:57

the research, obviously, I did it on a reversible pump turbine,

00:41:01

actual turbine - developing about 50 kilowatts of power

00:41:06

the entire rotors were machined by me right from scratch

00:41:10

from a bronze metal. I cast the material [inaudible]

00:41:14

Deckel Milling machine because they didn’t have labour

00:41:16

I worked in the [inaudible] I brought in my personal suitcase all these

00:41:19

machine components and assembled here and tested it.

00:41:22

I tested for 9 months, day and night.

00:41:27

My thesis will be ... external work is so much;

00:41:29

all the associated message systems calibrating them.

00:41:33

Nowadays, these people do not know what is an error analysis,

00:41:37

what is fabrication of a probe, 3-dimensional probe or

00:41:41

how do you measure the flow field in a

00:41:44

impeller - nobody knows. They can do maybe a

00:41:48

computer simulation, but how do you validate your -

00:41:51

[Prof. Idichandy] Yeah. [Prof. Ravindran] Computational Fluid Mechanics.

00:41:53

[Prof. Idichandy] That is something missing in our [Prof. Ravindran] That is something...is very

00:41:57

[Prof. Ravindran] much missing in our present training programme. [Prof. Idichandy] Ok.

00:42:02

Immediately, after you know, the initial stages I think

00:42:06

you had an opportunity to go - go to Germany

00:42:08

[Prof. Idichandy] on a - under a DAAD scholarship. [Prof. Ravindran] Yes.

00:42:11

Yeah, that was immediately after joining in 1971

00:42:14

after I finished my M.Tech.

00:42:16

there was an opportunity: I applied for a scholarship

00:42:20

to the Government of India, at that time there was a

00:42:22

all India quota and IIT Madras enjoyed a -

00:42:25

[Prof. Idichandy] Special [Prof. Ravindran] private quota, but I was too junior.

00:42:27

So, I could not get that.

00:42:29

So, I applied - I was lucky to get that lucky break I had.

00:42:32

So, I went along with senior people of my faculty

00:42:35

who were my teachers,

00:42:36

I went with them to Germany for training

00:42:39

and worked in a laboratory. There also, I had an opportunity

00:42:42

where the professor said we should teach - learn -

00:42:47

speak to me only in German language,

00:42:48

learn the language very nicely and do the work here.

00:42:52

You start an all these lectures in German language.

00:42:55

So, that also and they gave me total freedom

00:42:58

to develop the - even though I didn’t know

00:43:00

how computer program at that time.

00:43:02

Those days IBM 370 was the only computer

00:43:05

in IIT Madras and the telephone equivalent was there.

00:43:09

We used to have 2000 cards for the code.

00:43:13

So, all that was learned by me, newly in Germany

00:43:16

they supported me and when I wanted

00:43:19

to fabricate the turbine, they said, ok, I approached a private

00:43:24

company called Deckel Mill, actually we have lot of

00:43:26

copy milling machines from them.

00:43:28

When it was - I'm from IIT Madras, I would like to go, he said

00:43:31

we don’t have people, but you are welcome to

00:43:33

[Prof. Ravindran] come and use our machines. [Prof. Idichandy] I see.

00:43:35

I worked there, machined myself, 4 months, like maybe about

00:43:40

26-27 different types of blades, assembled them.

00:43:44

[Prof. Idichandy] It is not a copying - [Prof. Ravindran] Copying only, means

00:43:46

[Prof. Ravindran] but different types you know. [Prof. Idichandy] Ok.

00:43:48

13 blades of guide blades, axial for guide blades

00:43:51

and then 3 different rotors with 3 different profiles.

00:43:54

Each rotor having 6 blades.

00:43:57

I have to make them. So, cast them,

00:44:00

then copy mill them, finish them, check their profile,

00:44:04

if necessary, modify it.

00:44:06

I brought them, ok, assembled them;

00:44:08

[Prof. Ravindran] random at 2000 rpm which is not that you know. [Prof. Idichandy] Yeah.

00:44:11

[Prof. Ravindran] It is a real pump, real turbine what kind of pump

00:44:14

and turbine it was a machine for tidal performance.

00:44:18

So, associated planning of the

00:44:20

performance: how is the flow

00:44:23

distribution, 3-dimensional flow,

00:44:26

3-dimensional components of velocity

00:44:28

static pressure, dynamic pressures,

00:44:30

flow rates, completely measured,

00:44:34

then mechanical power, speed, torque, accurately.

00:44:40

So, that was the work - that was the...

00:44:43

[Prof. Idichandy] How long you were there in Germany?

00:44:45

[Prof. Ravindran] Nearly 2 and half years I was there.

00:44:47

[Prof. Idichandy] That was [Prof. Ravindran] Apart from language course;

00:44:49

[Prof. Ravindran] no, including language course. [Prof. Idichandy] Including language,

00:44:51

[Prof. Idichandy] Yeah. It was completely in a Technische University

00:44:54

[Prof. Idichandy] that [Prof. Ravindran] Munich, Munich, it was in the Munich.

00:44:56

And it was totally, it was a very nice experience

00:44:59

because there I could really see

00:45:02

the total advancement of

00:45:04

technology, experimental technology;

00:45:07

to measure things in a rotating machine,

00:45:12

that is measure the flow velocities static pressures.

00:45:15

On the rotor blade, transfer them through the slip rings

00:45:20

physically and then take the signal out and

00:45:22

it's ready for our interface, those days.

00:45:24

And even the 3-dimensional velocity probes

00:45:28

where you have the radial common velocity

00:45:30

[Prof. Ravindran] in water had minute as you know the cool it once. [Prof. Idichandy] Yeah.

00:45:38

6 of them in a 5 millimetre base

00:45:42

such was the quality of manufacture.

00:45:45

So, that was - that was real learning.

00:45:50

And since I could speak German language fluently,

00:45:52

I could talk to them and learn lot of this

00:45:55

very nicely because there I had my family with me - wife,

00:45:57

[Prof. Ravindran] son, so, we enjoyed ourselves. [Prof. Idichandy] I am surprised you know, how can -

00:46:01

[Prof. Idichandy] you said you got in Deckel, no.

00:46:03

[Prof. Ravindran] Deckel Milling Machine, yes.

00:46:06

How is that, you know, the...totally, you know, a strange

00:46:11

person from a very strange country

00:46:13

they just leave the equipment to you to

00:46:16

[Prof. Idichandy] you know fabricate whatever you want. [Prof. Ravindran] Yes.

00:46:18

That - that - that is what you know, the

00:46:19

universities had such a big respect from industries

00:46:24

[Prof. Ravindran] so, when somebody from a [Prof. Idichandy] Sure.

00:46:25

institute wants to come and work for their research,

00:46:28

they offer the facilities.

00:46:30

They like to involve with work.

00:46:32

[Prof. Idichandy] Ok. [Prof. Ravindran] With industries, you know.

00:46:34

I had a person from

00:46:36

who make automatic gears - car,

00:46:41

he is a CEO of the company.

00:46:44

So, when the university requested him to

00:46:46

come and take lectures on Hydraulic Systems

00:46:49

because it was the Hydraulic Torque Converters no,

00:46:52

he left half the job and then he said

00:46:55

1 hour per week only he will be take class,

00:46:58

but he said, I should be called only professor.

00:47:01

So, they have such a major

00:47:03

[Prof. Idichandy] Yeah. [Prof. Ravindran] respect for university systems.

00:47:06

And he used to take all the students to his company,

00:47:09

take them around give them good gifts

00:47:12

of tool kits, I still have those [inaudible] which is

00:47:14

[Prof. Ravindran] 55 years old. [Prof. Idichandy] Ok.

00:47:17

So, that was the respect of the

00:47:20

university by the industrial people.

00:47:24

So, you were in Munich two and half years

00:47:28

and you know Munich is most famous for its beer.

00:47:32

[Prof. Ravindran] Yes. [Prof. Idichandy] And the Oktoberfest.

00:47:34

[Prof. Ravindran] Yes. [Prof. Idichandy] I still wonder

00:47:38

how you have not even tasted beer.

00:47:41

[Prof. Ravindran] Yeah. At that time,

00:47:43

yeah, the problem was that, you know, that German beer

00:47:46

is the purest beer in the world. [Prof. Idichandy] Yeah

00:47:49

[Prof. Ravindran] By law they have prevented any

00:47:52

[Prof. Ravindran] flavors being added. [Prof. Idichandy] Added.

00:47:54

[Prof. Ravindran] So, so the German beer is very bitter.

00:47:57

I never loved the taste for German beer. [Prof. Idichandy] Ok.

00:48:07

to Oktoberfest where they drink from

00:48:09

11 o’clock in the morning to 11 o’clock in the night,

00:48:12

it is fun. People drink, eat, drink and then play music.

00:48:17

[Prof. Idichandy] Yeah. [Prof. Ravindran] It’s called the Oktoberfest music.

00:48:18

[Prof. Idichandy] Yeah. [Prof. Ravindran] All trumpets only.

00:48:20

So, in a tent there are about 30,000 people

00:48:24

sitting and eating and drinking and dancing.

00:48:27

[Prof. Idichandy] Yeah. [Prof. Ravindran] Great fun

00:48:30

but beer itself we never had a taste,

00:48:32

[Prof. Ravindran] but that beer is really bitter. German beer is [Prof. Idichandy] Ok.

00:48:36

[Prof. Ravindran] really bitter. [Prof. Idichandy] And they always consume

00:48:39

[Prof. Idichandy] the beer in 1 litre. [Prof. Ravindran] 1 litre.

00:48:41

[Prof. Ravindran] They don't sell anything less than 1 litre these - Oktoberfest time.

00:48:45

[Prof. Idichandy] Ok. Yeah. After your

00:48:49

very successful teaching, research, as well as

00:48:56

doing your - completing your Ph.D., everything,

00:48:59

after completing in the Turbomachines Laboratory, you joined

00:49:05

or shall I say you were forced to join Ocean Engineering Department.

00:49:10

No, not that way, but something

00:49:12

really happened, you know, at that time

00:49:14

the Director was Professor P. V. Indiresan. Indiresan.

00:49:18

And the Head of the Laboratory was Professor Raju.

00:49:21

So, Professor Indiresan is one person who wanted

00:49:25

the different faculty from different departments to work

00:49:28

together and take up major projects for

00:49:31

industries as interdisciplinary projects.

00:49:36

So, you will give me a thrust.

00:49:37

In this process, he formed a number of interdisciplinary

00:49:42

[Prof. Idichandy] Research groups. [Prof. Ravindran] research groups from [inaudible] faculty from

00:49:46

Electrical, Mechanical, Civil, Computer Science etcetera;

00:49:51

when they were taking up lot of projects, industrial projects

00:49:54

like the micro project in Shivaganga and all that.

00:49:58

So, they were doing that and at that time

00:50:01

there was a special interest on

00:50:06

renewable energy from the oceans

00:50:10

and Professor Indiresan felt that if at all anybody

00:50:15

could do the work on ocean energy,

00:50:20

it could be only IIT Madras Ocean Engineering Centre

00:50:22

and we should take initiative.

00:50:25

So, he took the interest to call for a

00:50:29

formation of a group of industry - faculty

00:50:33

to work on renewable energy sources from the ocean.

00:50:38

So, from the turbomachinery side, myself and Venkatrayulu were...

00:50:43

we volunteered to work

00:50:45

on the design of pumps and turbines, aspects of both

00:50:49

Ocean Thermal Energy and Wave Energy.

00:50:53

And there were people from

00:50:55

Ocean Engineering Centre like Professor Vendhan,

00:50:59

an instrumentation group like yourself and

00:51:02

Professor Bhattacharya, and Civil Engineering group

00:51:07

people maybe Professor Aravindan was

00:51:09

very - this thing - Electrical group,

00:51:12

Professor Laxmi Narayana. And Jagadeesh Kumar.

00:51:19

[Prof. Idichandy] Okay. [Prof. Ravindran] They were all ... involved.

00:51:21

So, we started working on very very preliminary

00:51:25

designs of Ocean Thermal Energies [inaudible] to start with.

00:51:30

And at that time, the Government of India started the

00:51:33

[Prof. Ravindran] new department of ocean development [Prof. Idichandy] Development.

00:51:36

[Prof. Ravindran] under the Ministry of Science and Technology.

00:51:39

Dr. Qasim, who went to Antarctica for the first

00:51:42

time taking the group from us, was made the secretary

00:51:46

and Professor Indiresan was always in touch with him.

00:51:50

And then Professor Indiresan

00:51:54

said that we are going to start this initiative

00:51:57

and Dr. Qasim said he will support that.

00:52:02

So, at that time the ministry of - or the department of

00:52:07

non-conventional energy source also was there

00:52:10

who had interest on Ocean Energy.

00:52:14

So, from these two departments of

00:52:17

Ocean - Ocean Development and

00:52:20

Ministry of Non-Conventional Energy Sources,

00:52:23

Professor Indiresan arranged some funding to be given

00:52:27

and formulated...created a cell called Ocean Energy Cell

00:52:31

[Prof. Ravindran] as a part of the Ocean Engineering [Prof. Idichandy] Centre.

00:52:33

[Prof. Ravindran] Centre of IIT Madras with industrial faculty.

00:52:37

So, at that time because we were

00:52:41

taking active part from Mechanical Engineering group on

00:52:44

pumps and turbines, aspects of both the

00:52:46

wave energy and this thing.

00:52:48

And he was also requesting us to develop the - or to

00:52:56

complete the wavemaker insulation,

00:53:00

[Prof. Ravindran] at that time which was bought from Germany and the installation was delayed. [Prof. Idichandy] Ok.

00:53:08

[Prof. Ravindran] As a person interested in turbomachinery,

00:53:10

especially there was a special

00:53:12

bi-directional airflow uni-directional turbine

00:53:15

called Wells turbine, which was of tremendous interest

00:53:18

for the Wave Energy Programme.

00:53:20

I wanted to work further on that.

00:53:22

So, we volunteered to commission that

00:53:24

wave energy, wavemaker in Ocean Engineering Centre.

00:53:28

So, first our job was - my job was to

00:53:31

commission as a faculty of Mechanical Engineering.

00:53:33

I offered support to commission that wavemaker

00:53:35

which was commissioned in about 6 months; we worked

00:53:39

day and night. Then, Professor Indiresan said, "Ravindran

00:53:42

now we know because there were no Mechanical Engineers

00:53:44

part of the faculty of Ocean Engineering at that time,

00:53:47

they were all only Civil Engineers,

00:53:49

structural engineers and instrumentation group headed by you.

00:53:53

So, there was no Mechanical Engineer there."

00:53:56

So, he said "We need you."

00:53:58

I was bit hesitating, saying that I had research students working in

00:54:01

Turbomachines Laboratory, then they said you could be a

00:54:03

adjunct faculty and all.

00:54:06

Then, when this funding came, specifically from both the ministries

00:54:10

to create a cell, he wanted somebody to head that

00:54:13

and he wanted me, I was bit reluctant, but he forced me to

00:54:17

apply - appear for it even though I didn’t apply.

00:54:19

So, I was given the opportunity to start this activity on

00:54:24

renewable energy from the oceans

00:54:25

and he could recruit more younger faculty, research staff

00:54:32

from other IITs also, from IIT Kharagpur, example

00:54:35

and then we started major activity

00:54:38

to study the different aspects of wave energy conversion,

00:54:43

the system which is practically useful for India,

00:54:47

for the type of wave climate we have in India.

00:54:50

The components of the system

00:54:52

where we select this system called Oscillating Water Column System,

00:54:55

there was work for optimizing the

00:54:57

hydrodynamic shape of that wave absorbing.

00:55:00

This converts the energy from the wave from the

00:55:04

waves to the air trapped in a chamber under [inaudible].

00:55:09

Then from the air to a mechanical shaft

00:55:12

through a turbine which is this bi-directional airflow turbine,

00:55:16

then a generator for it which will convert this mechanical energy

00:55:19

into air flow energy and pump power to the grid.

00:55:22

So, we had to design the total loop.

00:55:25

So, even though Professor Indiresan was a bit

00:55:28

in a hurry to do that we recommended that we have

00:55:32

3 research groups, independently,

00:55:34

to work on the hydrodynamic gas turbine energy

00:55:37

conversion of wave to water, air, hydrodynamic part of it.

00:55:42

Then, the mechanical turbomachine aspect of the

00:55:44

design of a special turbine

00:55:45

for pneumatic to mechanical conversion

00:55:48

and advice from electrical engineers to

00:55:51

select the right type of

00:55:53

machinery to convert cheap machinery to convert

00:55:57

mechanical to electrical engineering.

00:55:59

So, we had 3 different research topics given to Ph.D.

00:56:03

[Prof. Idichandy] Students. [Prof. Ravindran] students and we did a very good work

00:56:06

and based on that confidence,

00:56:09

then, we told Professor Indiresan we can go for a

00:56:11

field plant and we selected a site

00:56:14

at Vizhinjam, Kerala. We built one,

00:56:17

one of the first of its kind in the world, you know,

00:56:20

to generate 150 kilowatts. That was also a very big

00:56:27

learning crosses for us because it consisted of a caisson

00:56:33

3000 tons in weight. We built it on the - on the

00:56:39

harbour, Vizhinjam harbour, towed it to the site

00:56:42

and seated it 10 metre. Our first attempt failed

00:56:48

because of many reasons: we didn't have right tug,

00:56:50

we use some prefabricated

00:56:52

technology for slabs connecting them,

00:56:54

it started leaking, so...

00:56:56

[Prof. Idichandy] Probably, you could not also get contractors who can do

00:56:59

[Prof. Ravindran] Yes so [Prof. Idichandy] this type of -

00:57:01

Professor Raju used his contact with Larsen Toubro.

00:57:04

He said it is a national programme,

00:57:06

so they have to help us. So, like that

00:57:10

the Vice President of Larsen Toubro,

00:57:13

[Prof. Ravindran] Dr. Ramakrishnan. [Prof. Idichandy] Ramakrishnan.

00:57:15

Ramakrishnan was there and he agreed, even though

00:57:19

it was not a profitable business for them - it was

00:57:21

a technology demonstration capability of Larsen Toubro

00:57:25

for this project. First of its kind there caisson; fabricated

00:57:31

and floated out and then rest of the equipments

00:57:33

assembled on it, built a bridge to the shore which has

00:57:36

seated 50 metres away from the near breakwater.

00:57:40

So, that was also a tremendous

00:57:42

learning process and demonstration of capability of IIT Madras

00:57:45

on all the aspects and we commissioned that,

00:57:48

that's how I got involved then.

00:57:51

When we did that Professor Indiresan said

00:57:55

we want you to permanent -

00:57:55

I was a deputation of Mechanical to

00:57:57

this thing; then he said, "No, we want you to

00:58:00

permanently be in Ocean Engineering Centre."

00:58:01

So, I became a permanent faculty

00:58:03

of Ocean Engineering Centre.

00:58:05

And at that time only, also,

00:58:08

we have commissioned the second stage of German

00:58:13

support to us. We expand our facility to include

00:58:16

multi-element wavemaker. We formed a group of

00:58:19

multidisciplinary faculty from IIT, Ocean Engineering Centre,

00:58:23

your group and Sundaravadivelu's group doing the structural connections

00:58:28

and we did the mechanical part of that

00:58:31

[inaudible] running the sophisticated wave-making facility,

00:58:36

3-dimensional wavemaking

00:58:37

facility which was full of hydraulics.

00:58:39

Very complicated system of first of its kind installed.

00:58:42

And that way that time it was a

00:58:44

first thing which happened that

00:58:46

2 million German marks were used

00:58:49

[Prof. Ravindran] to buy an equipment not from Germany. [Prof. Idichandy] Yes.

00:58:52

[Prof. Ravindran] We bought that from Denmark. [Prof. Idichandy] Denmark.

00:58:55

So, that was also another thing we could,

00:58:57

because I was Head of the Department

00:58:59

we could convince the German representative

00:59:01

who was staying with us, one Dr. ?? We want the

00:59:05

best equipment which is affordable.

00:59:07

The German equipment was very very expensive.

00:59:09

An extension of a 4 metre flume would have been very expensive

00:59:13

which is hydraulic-based, this was servo motor base one.

00:59:17

So, that's how we got that equipment.

00:59:18

And it was a cooperation. We gave - IIT gave

00:59:22

20 million rupees, for the associated

00:59:25

structure facilities and infrastructure

00:59:28

[Prof. Ravindran] they gave us 2 million German marks [Prof. Idichandy] German marks.

00:59:31

for the especially imported equipment.

00:59:33

That's how we could commission this

00:59:37

[Prof. Ravindran] special facility which is unique in this part of the world. [Prof. Idichandy] Yeah.

00:59:41

[Prof. Idichandy] In fact, Ocean Engineering Centre at that

00:59:45

[Prof. Idichandy] time was probably the only one of its kind in South-East Asia [Prof. Ravindran] Yes true.

00:59:50

[Prof. Idichandy] which had most of the facilities under one roof.

00:59:55

[Prof. Ravindran] That too, even Germany did not have, you know.

00:59:57

[Prof. Idichandy] Yes. [Prof. Ravindran] And see there were facilities

00:59:59

under commercial or private this thing like

01:00:02

[Prof. Ravindran] National Hydronus Laboratory in Trondheim. [Prof. Idichandy] Yeah.

01:00:06

They were all privately owned laboratories.

01:00:08

Under a university system,

01:00:10

I think this was the first of its kind of the unique

01:00:12

facilities, so many facilities under one group.

01:00:15

I think that showed the success of our initiative in IIT Madras.

01:00:18

And Germans supported us very much.

01:00:21

I think that was a brainchild of

01:00:24

Professor Indiresan to develop this and

01:00:27

he had special interest in oceans.

01:00:29

[Prof. Idichandy] Yeah. [Prof. Ravindran] Because before he came to IIT Madras, he was in

01:00:33

Centre for Applied Research in Electronics.

01:00:35

There he has worked a lot of things on underwater

01:00:38

[Prof. Ravindran] acoustics, electronics, etcetera. [Prof. Idichandy] I think...

01:00:40

[Prof. Ravindran] So, he had a special interest in Ocean Engineering Centre. [Prof. Idichandy] Yes.

01:00:42

Even after his retirement he came and stayed with us

01:00:45

[Prof. Ravindran] as a faculty of Ocean Engineering Centre. [Prof. Idichandy] Just like us.

01:00:47

I think a lot of great support for him we developed this

01:00:50

in disciplinary group. I - now I think we have

01:00:53

lot of Mechanical Engineers and there are other

01:00:55

people in Ocean Engineering Centre. [Prof. Idichandy] Yes, correct.

01:00:56

[Prof. Ravindran] I think that was a vision of Professor Indiresan we should review. [Prof. Idichandy] Yeah.

01:00:59

[Prof. Idichandy] And he is totally a multidisciplinary. [Prof. Ravindran] Yes, yes.

01:01:04

[Prof. Idichandy] Coming back again to the - I think, no wonder the

01:01:07

[Prof. Idichandy] President of Germany himself came and [Prof. Ravindran] Came, yes.

01:01:10

[Prof. Idichandy] inaugurated it. [Prof. Ravindran] Yes. That was one of our

01:01:12

best achievement because till that time Ocean Engineering Centre

01:01:15

[Prof. Ravindran] never had any recognition even within India. [Prof. Idichandy] Yeah.

01:01:18

Even though we had done 1 or 2 projects for ONGC and all that.

01:01:22

The whole facility, the uniqueness

01:01:23

of Ocean Engineering Centre was not known to anybody

01:01:26

outside our Ocean Engineering Centre.

01:01:27

So, we sent, we requested the German department of GTZ

01:01:34

[Prof. Ravindran] German agency for technical cooperation. [Prof. Idichandy] Technical cooperation, yes.

01:01:37

To support us and they were also thrilled that

01:01:39

you know, they could bring the President

01:01:41

to inaugurate such a very important

01:01:43

example of that cooperation to us.

01:01:46

Even though Ocean Engineering Centre came very late into the

01:01:48

German aid program, and we have become a - such a

01:01:52

big advertisement for them

01:01:53

or, this thing we've achieved a very major result within a short time.

01:01:56

That was the happiness of German agency also.

01:01:59

They will like to also support us

01:02:01

[Prof. Ravindran] and that was a very good thing yes. [Prof. Idichandy] In fact, it was

01:02:03

[Prof. Idichandy] also a big news for the German media. [Prof. Ravindran] Yes.

01:02:08

[Prof. Idichandy] For the President came. And one of the aspects

01:02:11

which they projected was such a facility is not available in Germany.

01:02:15

[Prof. Ravindran] Yes. [Prof. Idichandy] Whereas, the government has supported,

01:02:17

[Prof. Idichandy] want to be created in the... [Prof. Ravindran] You know and

01:02:19

that was the greatness of German,

01:02:20

[Prof. Ravindran] they agreed to that otherwise. [Prof. Idichandy] Correct, correct.

01:02:22

normally a donor agency

01:02:24

never allows such a major equipment,

01:02:27

money to be spent outside Germany.

01:02:30

[Prof. Ravindran] They will like to use it for their own industrial support. [Prof. Idichandy] Correct.

01:02:33

[Prof. Ravindran] But this was - I mean, when we convinced them

01:02:35

they accepted that. I think that was a very magnanimous

01:02:40

[Prof. Ravindran] way in which they accepted. [Prof. Idichandy] Ok.

01:02:43

[Prof. Idichandy] I think the caisson - again it was rebuilt [Prof. Ravindran] Yes.

01:02:47

[Prof. Idichandy] second time. [Prof. Ravindran] Yes. After the first failure

01:02:49

when we could not place it

01:02:51

at the right place at the right tide.

01:02:56

We... it got damaged also during the big monsoon time.

01:03:00

We designed a stronger caisson little bit

01:03:04

[Prof. Ravindran] more of more surplus [Prof. Idichandy] Ok.

01:03:07

strength - that is factor of safety was slightly more.

01:03:10

And this was slightly constructed in a slightly different

01:03:17

procedure that the - only the basic raft was

01:03:21

[Prof. Ravindran] built on the shore. [Prof. Idichandy] Shore.

01:03:23

On the beach. Then we pulled the raft into the sea

01:03:27

and then built the super structure

01:03:29

of nearly 20 metres in the floating water.

01:03:33

[Prof. Ravindran] The whole raft was floating. [Prof. Idichandy] Yeah.

01:03:35

And that was a big challenge because

01:03:38

when we put concrete on one side

01:03:40

because of the floating mode it used to tilt.

01:03:42

So, keeping the right angle and the

01:03:44

strength and uniformity was a

01:03:46

big challenge to Larsen Turbo.

01:03:48

But still it was a very good demonstration of the

01:03:54

new capability of building this huge caisson

01:03:58

which was ballasted with 3000 tonnes of sand

01:04:01

to make it sit on the floor.

01:04:03

It became a gravity structure.

01:04:05

No foundations were added

01:04:07

and all - it was just sitting on a

01:04:09

prepared rubble bed which was prepared by divers.

01:04:13

And we built the turbine and

01:04:15

the generator afterwards, after building a connecting bridge

01:04:19

where there was no crane. It was purely, it was another

01:04:22

learning experience how to build a

01:04:25

50 metres long bridge from the breakwater to the

01:04:28

[Prof. Ravindran] caisson sitting in 10 metres water depth. [Prof. Idichandy] Ok.

01:04:31

So, without big crane, without a Harley crane of 2 tonnes capacity,

01:04:35

so, slowly like they build this a road, railway bridges now,

01:04:39

[Prof. Ravindran] we built extension; extension we built over the oceans. [Prof. Idichandy] Yeah yeah yeah.

01:04:44

[Prof. Ravindran] Yes, that was - [Prof. Idichandy] I think the second caisson worked

01:04:47

[Prof. Idichandy] probably about 15 years later. [Prof. Ravindran] Yes,

01:04:50

that is one of the longest

01:04:51

[Prof. Ravindran] working wave enery plant in a whole world. [Prof. Idichandy] World.

01:04:53

The Belfast people started one,

01:04:55

but that fell into the sea within about 2-3 years.

01:05:00

So, that way ours was the longest surviving.

01:05:02

We commissioned in 1989 that was the last eve,

01:05:06

[Prof. Ravindran] New Year Eve success, December 31st. [Prof. Idichandy] Oh, yes.

01:05:09

It was ... a happiness. After initial

01:05:12

failure it was a very great joy for all of us

01:05:14

when we seated it properly and then

01:05:16

slowly we added the turbine and generator,

01:05:18

we pumped power to the grid. Then, after the initial

01:05:23

system was commissioned with induction generator

01:05:27

that is induction motor, very conventional rendered machine,

01:05:31

Kirloskar machine, run at a speed higher than the

01:05:34

synchronous speed to work as a generator,

01:05:36

cheapest possible generator. But that was

01:05:39

very stiff, you know, torque slip characteristics

01:05:42

3 percent when speed is the

01:05:43

power went from 0 to 100 percent.

01:05:46

The wave characteristics didn’t match that very much.

01:05:49

We looked out for a very simple and rugged machine.

01:05:51

So, slowly we involved the faculty from

01:05:56

[Prof. Ravindran] Electrical Engineering like this fellow, Professor Jagadish Kumar. [Prof. Idichandy] Yeah.

01:05:58

He started a variable speed induction motor,

01:06:00

then control of the speed in line with the

01:06:03

power availability from the waves. We did lot of

01:06:05

research on the electrical machine also

01:06:08

plus which slowly change the type of

01:06:11

turbine from adjustable guide blades,

01:06:15

we have put adjustable guide blades,

01:06:16

then we fixed guide blades.

01:06:18

Then, we said that during monsoon

01:06:21

the power availability is so high

01:06:24

we designed for average power.

01:06:25

The peak power was nearly

01:06:27

[Prof. Ravindran] 10 times that of the average power. [Prof. Idichandy] Oh.

01:06:30

So, we said, "Why we should lose that peak power?"

01:06:33

So, we changed the type of design of the turbine from

01:06:36

reaction turbine, low pressure reaction to

01:06:38

high pressure impulse turbine,

01:06:40

similar to the work done by Japanese,

01:06:42

we have cooperation with Germany.

01:06:43

Then, we involved the faculty from Aeronautics Department

01:06:47

[Prof. Ravindran] the Professor Santhakumar. [Prof. Idichandy] Santhakumar.

01:06:51

[Prof. Ravindran] I think you are right.

01:06:52

He came and he developed a test rig also, done for the

01:06:55

Bio Nuclear Lab. So, it was a really

01:06:58

a wholehearted cooperation from faculty, we developed

01:07:01

new machines. We developed and we attained a very high

01:07:04

overall efficiency compared to anybody else in the world.

01:07:08

Only: our sadness is that we could not

01:07:15

put that in the harbour that was being built in the

01:07:18

[Prof. Ravindran] Valiyathura harbour. [Prof. Idichandy] Ok.

01:07:21

Near Kollam, there was a harbour project coming

01:07:23

not Valiyathura, near Kollam.

01:07:27

But...they said we are having stones which are very

01:07:31

cheaply available in the nearby hills.

01:07:34

So, our caisson was little more expensive.

01:07:36

So, we had planned all this, that this

01:07:39

path will be part of the breakwater,

01:07:40

as a multipurpose breakwater -

01:07:42

that we could not achieve because they could get -

01:07:45

because there's still; hills are available in Kerala to break.

01:07:49

So, you know environmentally it was not nice, but they said

01:07:52

this is the cheapest way we have the money only for this.

01:07:55

So, even though it was the best wave energy device we could develop,

01:07:58

we could not put it in a commercial ...

01:08:00

[Prof. Idichandy] Yeah. [Prof. Ravindran] production mode.

01:08:03

[Prof. Idichandy] Speaking about the economics of, you know, wave energy,

01:08:06

I think it is definitely not

01:08:09

comparable with the conventional energy

01:08:11

[Prof. Idichandy] that is probably the case with the - any - any - you know, [Prof. Ravindran] Yes.

01:08:16

[Prof. Ravindran] Yes, that is true. [Prof. Idichandy] non-conventional energy.

01:08:18

Because the two main reason is that, that the

01:08:22

wave energy varies; wave energy potential

01:08:25

of the wave varies continuously from

01:08:28

very low, almost 0 during calm period,

01:08:31

during the non- in between months like December and all.

01:08:34

It was very lull, you can see that it, like a lake,

01:08:37

compared to the monsoon it is June, July in Kerala,

01:08:40

it is peak we have 6 metre waves and 7 metre waves.

01:08:44

So, it's quite high. The ratio,

01:08:46

peak to average power is more than 10 to 15.

01:08:51

We have to design the structure to withstand the peak waves

01:08:53

[Prof. Ravindran] which is there for few days in a year [Prof. Idichandy] Correct, correct.

01:08:56

[Prof. Ravindran] whereas, you have to design the equipment for the average

01:08:58

for which is - so, that is the most difficult thing

01:09:01

[Prof. Ravindran] in a wave energy device in an country like India. [Prof. Idichandy] Ok.

01:09:05

That’s why we designed our system

01:09:07

as a multipurpose device where this caisson

01:09:10

when you put number of them in a row,

01:09:12

[Prof. Ravindran] it becomes a breakwater. [Prof. Idichandy] Yeah.

01:09:13

Instead of a stone breakwater with tetrapods

01:09:16

which dissipates the energy of the waves

01:09:19

to create a calm water behind in a harbour,

01:09:22

we said this will absorb and convert into electricity.

01:09:25

[Prof. Idichandy] In ... the same purpose. [Prof. Ravindran] So, this way it will be a

01:09:28

multi-purpose we can offset the extra cost

01:09:30

from the cost of breakwater.

01:09:32

[Prof. Ravindran] That's what we wanted to put in the Neendakara port. [Prof. Idichandy] Ok.

01:09:37

And somehow they said, still it is not

01:09:41

cheaper for them compared to stone breakwater.

01:09:43

So, in spite our best effort to convince the

01:09:48

Fisheries Ministry which was building,

01:09:50

[Prof. Ravindran] it was a fishing harbour, [Prof. Idichandy] Ok.

01:09:52

we could not do that.

01:09:53

But we are very confident that it is the best

01:09:55

device anywhere in the world [inaudible] see with our generators.

01:09:58

And Dr. Jayashankar who came in later,

01:10:00

unfortunately I should pay our respect to him, he is no more,

01:10:04

he was working on so many simulations of optimizing into

01:10:08

various components, electrical, mechanical, turbine,

01:10:11

hydrodynamics, etcetera, he was working much longer period

01:10:14

as a faculty he came from NIOT to IIT faculty.

01:10:18

And then, he has come with a very solid modelling proof

01:10:23

that the government system could be cheaper.

01:10:26

[Prof. Idichandy] Right. [Prof. Ravindran] any time.

01:10:27

So, he was negotiating with some people abroad for the project

01:10:33

and somebody was even willing to take his advice for certain funding.

01:10:42

They asked him: not to public?

01:10:43

He said, no, this technology is available,

01:10:46

is to be used by everybody

01:10:48

who is interested in renewal energy.

01:10:50

[Prof. Ravindran] So, he was not willing to sell this or restrict this technology [Prof. Idichandy] Right.

01:10:54

[Prof. Ravindran] to a particular agency. So, he didn’t do that.

01:10:59

He didn’t give the technology to them

01:11:02

and unfortunately, he passed away because of certain illness

01:11:07

[Prof. Ravindran] due to cancer. [Prof. Idichandy] Yeah.

01:11:08

So, I think that initiative has come down to this.

01:11:12

So, we are waiting still for a oil price to increase or

01:11:16

this place to come down.

01:11:18

[Prof. Idichandy] Yeah. I think later on the

01:11:21

power produce sort of so been used for desalination work.

01:11:25

[Prof. Ravindran] Yes, in order to demonstrate the multipurpose capability,

01:11:29

the Vizhinjam harbour has lot of fishermen who use lot of ice.

01:11:34

And also they need drinking water,

01:11:36

because during the previous monsoon, the

01:11:38

daily [inaudible], they have severe drought in these fishing harbours.

01:11:41

So, we had put desalination plant run by purely wave energy.

01:11:48

And demonstrated that we could give them everyday

01:11:51

at least 5000 litres of water from this small plant

01:11:53

[Prof. Idichandy] Ok. [Prof. Ravindran] purely run by wave energy and it was running for quite some time.

01:11:57

Well, I guess the - the - the total expenditure on this

01:12:03

like security because that is on the harbour.

01:12:05

Then, maintenance and because this is in the

01:12:08

corrosive one, environment, so that was bit high,

01:12:11

even though it could have been done.

01:12:13

So, we wanted the Kerala Government to take over

01:12:15

somehow they didn’t want to take over

01:12:17

because of the expense, they said we don't have budget.

01:12:19

So, after we were very confident that we have enough technology,

01:12:22

demonstration capability, demonstration done,

01:12:26

and then any day we can design a

01:12:28

commercial system, we said: ok, we will stop

01:12:31

and then we said we will dismantle the system.

01:12:34

So, after nearly 25 years, we have dismantled the system.

01:12:40

[Prof. Idichandy] Yeah. See, it's - it’s unfortunate, you know

01:12:43

you've put in so much of effort because lot of technology,

01:12:46

lot of, you know, knowledge has been generated from it,

01:12:50

but ultimately you know it could not be

01:12:53

used on a - on a commercial scale.

01:12:56

[Prof. Ravindran] Yeah. [Prof. Idichandy] Even if it is little expensive.

01:12:58

[Prof. Ravindran] Yeah, that is a tragedy in India I will say, this is my personal opinion.

01:13:02

You see, tidal power plant, the first ever plant was commissioned in

01:13:06

France, Rance, in 1966. 50 years it is working, still working.

01:13:13

Initially, it was known it is expensively - barrier,

01:13:17

the civil engineering construction cost of the barrier is expensive,

01:13:19

but now, having seen how much energy it has produced.

01:13:24

[Prof. Idichandy] Yeah, it's - [Prof. Ravindran] and now people want to build,

01:13:27

but India which has got a tremendous potential in Gulf of Cambay,

01:13:30

Gulf of Kutch, and feasibility

01:13:33

studies have been done for the last 20 years repeatedly.

01:13:37

Government have never took a decision

01:13:39

[Prof. Ravindran] to go for a tidal power plant [Prof. Idichandy] Tidal power.

01:13:42

which would have helped the Saurashtra region,

01:13:44

Marashtra region very much.

01:13:45

They were very clear designs done for a

01:13:49

[Prof. Ravindran] 800 megawatt plant in Gulf of Kutch. [Prof. Idichandy] Oh.

01:13:52

[Prof. Ravindran] 25 years ago. [Prof. Idichandy] Oh my god.

01:13:54

In the Ministry of Water Resources

01:13:56

there was a dedicated Chief Engineer, one Mr. H. R. Sharma

01:14:00

who got frustrated, he went to Mauritius,

01:14:03

really, after having done so much of work.

01:14:05

Similarly, we did a feasibility study after NIOT was started, oceans engineering centre.

01:14:08

We, ourselves, Professor Raju

01:14:10

was the coordinator, we did a feasibility [study] for Sundarbans.

01:14:13

We said we'll put a small plant, entire technology will be ours.

01:14:17

3 megawatt plant at the cost of about 3 crores or 4 crores

01:14:23

with a standby diesel power plant for the hospitals to be started.

01:14:27

Government, they worked on it for years, they didn’t take a decision.

01:14:31

So, somehow I feel that there is a reluctance

01:14:36

to go for a renewable energy plant in our country,

01:14:39

always quoting that it is expensive, expensive;

01:14:42

expensive from what sense? In a place like Sundarbans

01:14:45

[Prof. Ravindran] when there is no other power available. [Prof. Idichandy] Correct.

01:14:48

Like ... the first the Chairman, Atomic Power Commission

01:14:54

said, you know, no energy is costly than the position of no-energy,

01:14:59

[Prof. Ravindran] that our people have never understood. [Prof. Idichandy] Ok.

01:15:01

And we have been also highlighting the water plant

01:15:04

which was later - there also similar thing happened.

01:15:07

They were always asking where is the -

01:15:09

first plant they want to be commercially viable.

01:15:11

[Prof. Idichandy] Yeah. [Prof. Ravindran] See, same yardstick is not used for all ministry.

01:15:16

For example, ISRO they have put so many rockets

01:15:19

which was not commercially viable

01:15:20

or it was not technologically successful.

01:15:23

[Prof. Idichandy] Yeah. [Prof. Ravindran] Slowly, they have taken 30-40 years to

01:15:27

[Prof. Ravindran] come to a commercially viable stage. [Prof. Idichandy] Yeah.

01:15:29

That lead time was not coming to ocean technology or ocean energy,

01:15:32

that is my personal disappointment from the - our ministries.

01:15:40

[Prof. Idichandy] Yeah. And it’s - it's very strange you know

01:15:42

sometimes when it comes to political will,

01:15:46

it lacks because of I don't know

01:15:48

whether they have no confidence,

01:15:50

always in a 'I can blame, that it is not commercially viable,

01:15:53

so therefore, we are not going to - not going to support.'

01:15:56

[Prof. Idichandy] I think it is [Prof. Ravindran] Yes.

01:15:58

[Prof. Idichandy] very unfortunate. [Prof. Ravindran] We always trust first we have to prove

01:16:01

[Prof. Ravindran] technical viability first. [Prof. Idichandy] Yeah.

01:16:02

It takes few years of lead time -

01:16:05

till that is technically feasible, don’t ask about commercial viability.

01:16:08

[Prof. Idichandy] Yeah, exactly. [Prof. Ravindran] Because by that time maybe the commercial, like deep sea mining.

01:16:12

Even yesterday’s paper there was a report on deep sea mining.

01:16:16

We have been working on 20 years, and I was working on;

01:16:18

slowly we see that in this 20 years time it has became a viable.

01:16:22

[Prof. Idichandy] Yeah. [Prof. Ravindran] The cost of the cobalt, nickel, and this thing has gone up,

01:16:25

but if we start with technology we'll not be there, we'll be

01:16:27

[Prof. Ravindran] demonstrating next year. [Prof. Idichandy] That's correct.

01:16:29

Because if start with technology today

01:16:31

would have been another 20 years to mine this.

01:16:33

See, this is what our government is not accepting or understanding.

01:16:38

Always there is a lead to prove the technology

01:16:42

till it is proven commercially viable.

01:16:47

[Prof. Idichandy] Ok. Let us hope that there will be some change in the mindset of [Prof. Ravindran] Yes.

01:16:51

[Prof. Idichandy] the government. [Prof. Ravindran] Yes.

01:16:53

[Prof. Idichandy] Ok. Let us probably start with NIOT, next phase. [Prof. Ravindran] Yes.

01:17:00

I think the talk for starting a National Institute of Technology

01:17:06

or Ocean Technology for quite some time.

01:17:09

[Prof. Ravindran] Yes. [Prof. Idichandy] Because National Institute of Oceanography is there

01:17:15

[Prof. Ravindran] '66 onwards. [Prof. Idichandy] Yeah.

01:17:16

It was started long back, but then there is nothing on technology.

01:17:21

Every time there is, something is talked about, the - the - the -

01:17:25

I mean, the - the government or the department has to come to IIT

01:17:28

and probably the navy to some extent.

01:17:32

So, then this National Institute of Ocean Technology was thought of.

01:17:40

Probably, again Indiresan was behind it

01:17:44

and East Coast was taken was one of the places where it is

01:17:51

likely to come up. And then considering

01:17:54

all aspects especially the proximity of

01:17:56

IIT Ocean Engineering Department,

01:17:58

it has been decided to establish the centre

01:18:02

in - in Chennai to start with an IIT itself.

01:18:07

[Prof. Idichandy] That's a very wise decision, of course. [Prof. Ravindran] Yes.

01:18:09

[Prof. Idichandy] Both NIOT as well as IIT got benefitted

01:18:12

[Prof. Ravindran] Yes. [Prof. Idichandy] because of it.

01:18:13

[Prof. Idichandy] I think you were in the thick of -

01:18:15

[Prof. Ravindran] Yes. [Prof. Idichandy] you know, the entire establishment of the institute.

01:18:19

I think you should elaborate a little on that.

01:18:22

Yeah. Ever since the Ministry of Ocean Development was was started in 1982,

01:18:29

there was talk about ocean ... Dr. Qasim,

01:18:33

who felt the need for this.

01:18:35

Till that time, you know, from '66 when

01:18:39

people started talking about oceanography,

01:18:43

ocean technology need was not appreciated

01:18:46

till the offshore platform started coming.

01:18:48

[Prof. Idichandy] Yeah. [Prof. Ravindran] The entire technology for offshore oil

01:18:53

exploration was higher technology.

01:18:55

There was nothing indigenously available.

01:18:57

For every small thing, we have to pay through our nose

01:19:00

and ONGC slowly started developing

01:19:04

its own core strength from its [inaudible] team engineers.

01:19:07

And another thing is that the people, who knew oceans, the naval people,

01:19:14

they never understood the deepwater technology.

01:19:18

There was no need for them to understand deepwater technology.

01:19:20

For them the submarine operation depth was

01:19:23

[Prof. Ravindran] less than 300 metres. [Prof. Idichandy] That's correct.

01:19:25

So, they were happy.

01:19:27

So, the authorities or the advisors for the government authorities

01:19:34

never felt the importance of developing a capability

01:19:37

in deep sea technologies or offshore engineering proper.

01:19:40

[Prof. Idichandy] Yeah. [Prof. Ravindran] Till they realize, ok, offshore oil is one

01:19:43

but there are so many other thing

01:19:44

which are more - also equally important in offshore engineering

01:19:48

other than offshore oil platforms.

01:19:50

I think that came known to them

01:19:52

only after Ocean Engineering Centre was started.

01:19:54

[Prof. Idichandy] Yes. [Prof. Ravindran] When even before the [inaudible] could be commissioned,

01:19:57

I think you are the first to do demonstrate the launching capability of

01:20:00

offshore platform indigenously from our own platform.

01:20:05

So, people started understanding here;

01:20:06

capability is being built in Ocean Engineering Centre

01:20:09

and there is a need to go to

01:20:11

other unknown areas of deepwater technology.

01:20:14

So, that way, again, Professor Indiresan’s

01:20:17

idea was there. He had a very close

01:20:21

personal equation with Dr. Qasim

01:20:24

[Prof. Ravindran] because I think Indiresan daughter went to Antarctica. [Prof. Idichandy] Yeah.

01:20:27

And at day - at that time when Dr. Qasim proposed

01:20:32

in the first instance I think the end of 6th 5-year plan or something,

01:20:37

they'd prepared a totally green field, the institute budget with multiple,

01:20:42

I think about 80 or 100 crores.

01:20:48

Government had said no, no,

01:20:49

we don’t have money to start a green field institution.

01:20:51

So, they just closed it.

01:20:54

Then, it was lying low, then Professor Rama Rao came,

01:20:58

N. P. Rama Rao who was the

01:21:00

Secretary of Science and Technology, who was also in charge of

01:21:03

Ocean Development, Department, Ocean Development.

01:21:06

So, our Professor Raju and Professor Swamy

01:21:10

who was the then Director

01:21:14

when they went for discussion sometime with

01:21:16

DST said, we should take over.

01:21:18

I think Professor Raju was the main trust

01:21:20

that we should have a Institute of Ocean Technology

01:21:23

and we should do that.

01:21:24

And they say we don’t have much money.

01:21:27

So, then the Director offered that,

01:21:30

we offer the administrative support;

01:21:32

it could be started within the IIT campus,

01:21:34

they can use all the facilities of IIT in the R and D because

01:21:37

it is the interdisciplinary technology development institution.

01:21:41

They can use all our existing facilities.

01:21:43

So, we don’t have to create immediately a

01:21:45

huge infrastructure and other administrative support

01:21:49

we can give; security administration and other things.

01:21:52

So, you give us minimum money, we will start.

01:21:55

Then they said, where is the director?

01:21:57

we said: we also give one of our faculty

01:21:59

with that only it came in to be

01:22:01

[inaudible] was promoted - submitted by Dr. Rama Rao.

01:22:07

And for the first year, the budget was hardly 40 lakhs.

01:22:14

IIT accepted that, ok, give us 40 lakhs

01:22:16

maybe give us something more for the other 2 years the - initially

01:22:19

remaining parts of that 5-year plan

01:22:21

I think 7.5-year plan was hardly 2 crores

01:22:25

or so, for the entire 2 and half years or so.

01:22:28

IIT accepted that. They said we will provide our facilities to start.

01:22:33

So, give us project to individual departments

01:22:35

and then we will start working.

01:22:36

That’s how the NIOT came into being,

01:22:40

[Prof. Ravindran] otherwise NIOT would not have been started at all. [Prof. Idichandy] Started.

01:22:44

So, that real - this thing - thanks to go to IIT Madras,

01:22:49

the then Directo,r and Professor Raju.

01:22:51

And then, it so happened that they recommended my name

01:22:58

that we we will depute; even without my - they didn’t discuss

01:23:01

with me the idea. So, and at that time only the...

01:23:03

I just completed my term of Head of the Department.

01:23:05

And I was had more time. He said: ok, we will give Ravindran.

01:23:10

Even though it was a surprise to me,

01:23:12

it was not discussed with me,

01:23:13

I accepted because I just committed.

01:23:15

So, I was thankful for the confidence they had in me.

01:23:18

So, I said: it is a big challenge starting on Ocean Technology.

01:23:22

So, we have to right from

01:23:23

beginning, we need to look for land onwards, you know,

01:23:25

right from scratch we have to start

01:23:27

that was a big challenge, we accepted that,

01:23:29

and with all the cooperation from the Ocean Engineering Centre

01:23:34

and this thing, we started. And then within two years

01:23:38

the secretary of Ocean Development changed,

01:23:42

we got Dr. Muthunayagam who was the

01:23:47

senior person from ISRO. He came into the Oceans

01:23:51

and he is a man of the hardware type

01:23:55

because they are used to having projects

01:23:57

[Prof. Ravindran] with that time-bound delivery. [Prof. Idichandy] Yeah.

01:23:59

With no restraint on expenses, time frame,

01:24:03

they are all always project - time-based project.

01:24:07

So, when he took over in '95,

01:24:11

[Prof. Ravindran] we started in '93, November, [Prof. Idichandy] Yeah.

01:24:13

He said, he told me: Ravindran, why not we expand?

01:24:19

As long as we are restricted to this one

01:24:22

floor in ICSR building which built with that 40 lakhs first year,

01:24:27

he said you will still remain only as a pure R and D.

01:24:32

You cannot explain your activity.

01:24:35

There are so many different activities

01:24:37

to be taken up and this place is not sufficient.

01:24:40

So, we should look for a place at least 50 acres,

01:24:43

look for a place. So, we took a policy decision, ok.

01:24:46

Look for a place and build it.

01:24:50

As he said: no, we should build it within 2 years,

01:24:54

we don't have even a land you know at that time,

01:24:56

we didn’t have the money, but we took this challenge.

01:24:59

And then we asked the Government of Tamil Nadu

01:25:05

to give us some land. They wanted to give us some

01:25:08

land very far away or give us only

01:25:09

few grounds you know less than a acre for the institute.

01:25:13

We said no, give us the land which nobody else wants.

01:25:17

So, we got this garbage dump area

01:25:19

in Pallikaranai which was a marshy land with 7 feet of water.

01:25:23

We said: ok, give us, we will develop it.

01:25:25

So, that time the Commissioner of Land Administration

01:25:28

one Mr. Narayan IAS, very nice gentleman,

01:25:31

who later became Chief Secretary.

01:25:33

Within a very short time, he allotted 50 acres of land within

01:25:39

Madras city which was a very big gesture on the

01:25:42

part of the Tamil Nadu government.

01:25:45

And now, we could build this campus in

01:25:49

18 months as required by our secretary.

01:25:53

And that was the first time we committed

01:25:55

in writing to Planning Commission:

01:25:56

there will be no cost escalation

01:25:58

and time escalation and we did that.

01:26:01

So, there was a tremendous appreciation from

01:26:03

everybody concerning the Planning Commission

01:26:04

everybody, and that was one of the

01:26:06

nicest campus ... we have developed

01:26:08

from a garbage dump area with so much of facilities.

01:26:11

Even before the official commissioning we started work there like deep sea

01:26:14

mining technology, all works were started,

01:26:16

many projects were started in the ocean

01:26:18

apart from OTEC: data buoy programme, deep sea mining technology,

01:26:23

marine instrumentation, you know, to the activities there.

01:26:26

Then, later we added the data buoy programme

01:26:29

and they we built ships for ourself.

01:26:33

Go into the sea, because

01:26:34

without going into the sea, what do they learn?

01:26:37

So, we said we should survey and take sample from deep sea,

01:26:41

see, we built two small ships, later we built two big ships

01:26:46

which became really the best ships

01:26:49

[Prof. Ravindran] in our part of the country as a technology demonstration vessel. [Prof. Idichandy] Ok.

01:26:53

Which goes almost our - to southern oceans.

01:26:55

[Prof. Idichandy] Yeah. [Prof. Ravindran] To about 60 degrees South

01:26:58

and all that, it has gone.

01:26:59

So, such capability we have developed

01:27:00

[Prof. Ravindran] within a short time. [Prof. Idichandy] Yeah.

01:27:02

Yes. That is how the ocean technology...

01:27:04

and I took retirement in 2004.

01:27:07

It is 10 years, we did all these

01:27:08

the budget increase from 40 lakhs per year

01:27:11

first year - to more than 100 crores per year

01:27:13

when I retired and we had about 300 people

01:27:16

working for the institute. Nice campus, nice campus,

01:27:19

beautiful, with excellent facilities

01:27:22

technology-wise, capability-wise during the time.

01:27:27

[Prof. Idichandy] Ok. NIOT, to tell something about the

01:27:32

the these technology demonstrators

01:27:35

[Prof. Idichandy] done by the NIOT. [Prof. Ravindran] Yes.

01:27:39

Because they only even starting with water

01:27:41

[Prof. Ravindran] desalination. [Prof. Idichandy] Yes.

01:27:44

The first project which we came into

01:27:47

actual service to the humanity

01:27:50

in - in - in India is the data buoys programme

01:27:54

in which we have deployed data buoys floating around

01:28:00

in the Arabian Sea and the Bay of Bengal,

01:28:02

number of them, 12 of them.

01:28:03

They have all the ocean parameters and the

01:28:06

air parameters above the ocean.

01:28:08

One of the important requirements for

01:28:10

predicting our rainfall, cyclones, and storms was that the

01:28:19

[Prof. Ravindran] air-sea interaction, the weather or the [Prof. Idichandy] Yes.

01:28:22

air parameters just above the sea.

01:28:25

We didn’t have any offshore stations earlier.

01:28:28

So, we have to depend only from islands

01:28:29

like Andaman or Lakshadweep, in between we didn’t have

01:28:32

any measurement station. So, IMD was handicapped,

01:28:34

MET department was handicapped.

01:28:36

So, this data buoys give very very well information on the

01:28:41

energy coming from the oceans which are being

01:28:44

transferred to the air or the atmosphere

01:28:47

and change into rain or hurricanes or monsoon.

01:28:50

So, that became a very important contribution,

01:28:53

within I think '97, we commissioned that.

01:28:56

Our whole institute was started in '93,

01:28:59

that was one of the first solid contribution

01:29:02

to our society to understand the oceans - understand -

01:29:07

safeguard the coastal population from

01:29:09

hazards like hurricanes and storms.

01:29:12

That was the first one.

01:29:15

Then we started the Ocean Thermal Energy

01:29:17

conversion against the opposition

01:29:20

by Ministry of Non-Conventional Energy Resources

01:29:21

because that you are supposed to do, it

01:29:23

is not economical, they were opposing, opposing, opposing.

01:29:26

Actually, our Ministry Dr. Muthunayagam fought and took up this project.

01:29:31

With so much of opposition from many people

01:29:34

I - I don't want to name the people or the organization

01:29:37

who were opposing, when whole thing -

01:29:40

it was again a 2-year project, you know that we draw water

01:29:46

from 1000 metre water depth through a

01:29:48

[Prof. Ravindran] vertical pipeline hanging from the barge. [Prof. Idichandy] Yes.

01:29:50

Where all the equipment, power plant equipments are there,

01:29:52

all the plants, all the equipments about the barge, specially built

01:29:58

barge Sagar Shakti, which was built in Goa shipyard

01:30:02

within 18 months was tested.

01:30:05

Only the coded well could not be tested because

01:30:08

we have to go to the ocean to ... testing it.

01:30:10

It is tragedy that our country doesn't have

01:30:14

any offshore crane, even today.

01:30:17

We have to handle 200 tonnes of the anchor for the cold water pipe.

01:30:20

So, because like ONGC and all they hire this

01:30:24

crane from offshore for that season between December to April.

01:30:30

Then they go back to Dubai or Singapore.

01:30:32

So, when I went to Singapore and asked

01:30:35

for these people to come and place it,

01:30:38

yes, we erect with warranty, but the Defence Department

01:30:45

totally refused to give security clearance for this.

01:30:49

And he said: I want advance payment of

01:30:52

1 million dollars for the entire contract

01:30:55

because the payment delays are unacceptable to me.

01:30:59

I have seen from other experience. So, I want it.

01:31:02

These two conditions were

01:31:05

[Prof. Ravindran] refused by the Ministry. [Prof. Idichandy] Ministry.

01:31:08

They said use some other equipment which is available.

01:31:10

We have to hire a A frame without a - even a

01:31:13

crane possibility using a winch which failed,

01:31:17

which was supposed to have been tested by -

01:31:19

supposed to have been tested by Lloyd's.

01:31:21

So, we lost the cold water pipe.

01:31:23

So, everybody was objecting to the project said, we know

01:31:29

this is what will happen. It was a very very

01:31:33

unsympathetic remark by the officials,

01:31:37

and the other ministries, we felt very sad.

01:31:39

And out of, I don't know whether I should say that

01:31:44

total project about 30 crores, this damage was only 5 crores. We could have

01:31:48

[Prof. Idichandy] Ok. [Prof. Ravindran] renewed because the entire platform,

01:31:51

everything was tested and ready.

01:31:53

They said we will not give any more money.

01:31:55

So, we have to close the project.

01:31:57

That was one of the saddest part of my career in NIOT

01:32:01

[Prof. Ravindran] but we didn’t stop there, [Prof. Idichandy] Yes.

01:32:02

[Prof. Ravindran] Yes. [Prof. Idichandy] You know, it’s very sad, you know.

01:32:05

[Prof. Ravindran] Yes. [Prof. Idichandy] Some - I do not know whether it is bureaucrats or technocrats,

01:32:10

it take decisions without looking every aspect and then...

01:32:14

So, when other ministries were given

01:32:16

[Prof. Ravindran] so much time and money to prove the capability. [Prof. Idichandy] Yes.

01:32:19

They expect our first plan to be commercially successful,

01:32:22

commercially, say 1 megawatt

01:32:23

which have been the first commercial plan in the whole world

01:32:26

[Prof. Ravindran] they didn’t give us a chance to prove. [Prof. Idichandy] Ok.

01:32:28

Except one common fail, as it wind up the project.

01:32:32

The then Finance Minister wrote: good money for a bad project,

01:32:38

it was very very sickening to read.

01:32:41

[Prof. Idichandy] From the Finance Minister.

01:32:43

[Prof. Ravindran] What does he understand?

01:32:45

[Prof. Idichandy] Yeah, that's what. [Prof. Ravindran] Very unsympathetic remark

01:32:49

and this thing and based on that we were not given any money.

01:32:52

So, the entire 30 crores was left unutilized, scrapped.

01:32:58

[Prof. Idichandy] So, in fact, the real loss is only about 5 crores. [Prof. Ravindran] Yes.

01:33:03

Not - not even you know.

01:33:04

If we were allowed that crane to have been hired,

01:33:07

the right equipment to be hired at the right time,

01:33:09

we could have done that for same.

01:33:10

[Prof. Idichandy] Yeah. [Prof. Ravindran] We were not allowed.

01:33:12

So, we were asked to fight with our folded hands.

01:33:15

You have to work with whatever is available. And we failed.

01:33:20

[Prof. Idichandy] Okay. [Prof. Ravindran] So, but we didn’t

01:33:23

keep quiet. We...took up the other projects of

01:33:26

deep sea mining to mine polymetallic nodules

01:33:32

which are lying on the surface of the seabed at 5000 metre depth.

01:33:35

[Prof. Idichandy] Yeah. [Prof. Ravindran] And they are 2 kilo - 1000 kilometres away

01:33:38

from the Kanyakumari - South - Central Indian Ocean Basin.

01:33:42

So, we said we'd programme in steps.

01:33:46

First, you know, we develop a crawler,

01:33:49

and because we have never worked

01:33:51

more than 300; nobody has touched bottom and work.

01:33:55

So, as we should demonstrate capability

01:33:58

to work about 150-200 metres,

01:34:00

develop a crawler machine which will move on the seabed,

01:34:04

do some work and pump that

01:34:07

[Prof. Idichandy] Yeah, slurry, whatever it is. [Prof. Ravindran] soil up.

01:34:09

So, our technology was that we would pick up the nodules

01:34:11

crush it and send it through a hose, flexible risers.

01:34:14

So, we wanted to prove in stages. So, that was proven first.

01:34:18

We developed a crawler, first in - in this part of the world,

01:34:21

demonstrated off Tuticorin. Then re-demonstrated 500,

01:34:26

first 150 metres then 500 metres on West Coast

01:34:29

then we deployed because the nodules

01:34:32

are available only in 5000 metres.

01:34:34

[Prof. Idichandy] Ok. [Prof. Ravindran] So, to prove that availability, we

01:34:37

made artificial nodules and picked up these nodules.

01:34:40

Capability of picking up these nodules,

01:34:43

crushing, pumping, we demonstrated.

01:34:44

So, all those sub stages gone. So, now, we have to design - the NIOT -

01:34:48

designing the final version for 6000 metres

01:34:53

which is capable of pumping something like

01:34:57

[Prof. Ravindran] 8 kg of nodules [8 tonnes*] per hour [Prof. Idichandy] Ok.

01:35:01

with the slurry of about 10 percent by volume and which is

01:35:06

[Prof. Ravindran] pumping through a host 6000-metres long, [Prof. Idichandy] Yeah.

01:35:10

getting power supply also through a cable 6000-metres long.

01:35:14

So, how to install it, how to recover it, it is a big technology.

01:35:18

[Prof. Idichandy] Yeah. [Prof. Ravindran] So, slowly our engine start working. And we are hopeful that

01:35:23

the first the crawler we demonstrated in 2018,

01:35:26

and the full integrated test will be in 2020, that is our project.

01:35:31

So, we start work something like 10 years ago.

01:35:35

15 years ago, preliminary work was started, but

01:35:38

this we are done, it's a very tough technology because

01:35:40

[Prof. Ravindran] components are all not available [Prof. Idichandy] Yeah.

01:35:43

internationally, so, we have to develop most of the thing ourselves.

01:35:46

To prove the success of these things in deep sea water

01:35:50

because environment is very difficult

01:35:51

[Prof. Ravindran] 600-times atmospheric pressure, you know. [Prof. Idichandy] Yeah.

01:35:53

[Prof. Ravindran] 1000 times denser than the air. [Prof. Idichandy] Yes.

01:35:56

So, the forces are high, depths are unreachable.

01:36:00

So, the - no components is proven in

01:36:03

6000 metres, so far industrially.

01:36:05

So, we buy equipments and

01:36:08

[Prof. Ravindran] provide special casings [Prof. Idichandy] Casing.

01:36:10

to withstand and test about 900 bar.

01:36:12

50 percent more pressure.

01:36:13

So, that facility has been created, infrastructure.

01:36:16

So, these are the new type of the - such a facility doesn’t

01:36:20

[Prof. Ravindran] exist anywhere in this part of the world. [Prof. Idichandy] Exist.

01:36:22

[Prof. Ravindran] Even defence, you know, they have only 600 metres depth testing. [Prof. Idichandy] Yes.

01:36:25

Then fuel has, you know, like that.

01:36:27

So, building and creating facility itself is

01:36:30

a technology by itself.

01:36:32

Then, to go and survey this,

01:36:34

we have developed a remotely-operated vehicle.

01:36:37

Now, people know Titanic and people have gone in a -

01:36:39

people do not know: in India we have developed a

01:36:42

much better version to go to deeper waters.

01:36:46

We have published but now,

01:36:47

people are not really appreciating.

01:36:49

[Prof. Idichandy] Yeah. [Prof. Ravindran] See, your capability and we have done

01:36:52

underwater, ROV to work in Antarctica,

01:36:55

we went under the ice and bored at the bottom.

01:36:57

So, these capabilities we have developed, very unique facilities

01:37:01

which was never existing in our country.

01:37:02

So, we are - NIOT is very proud of this

01:37:04

capability and now after the tsunami...

01:37:08

[Prof. Idichandy] Yeah, 2004. [Prof. Ravindran] It was said that

01:37:12

yes, 2004, there was a strong need felt,

01:37:16

understandably, that we should have a warning system

01:37:19

even though it was very difficult to

01:37:20

have a very long advanced system.

01:37:22

Even 2 hours warning will be good enough.

01:37:24

So, we have put tsunami warning system

01:37:26

that is the special sensors, you are aware,

01:37:29

pressure sensors which sense the

01:37:31

surface variations of that. Once we recognize that,

01:37:34

nature immediately gives a warning.

01:37:36

[Prof. Idichandy] Yeah. [Prof. Ravindran] Through our data buoy system

01:37:38

acoustically from the bottom 4000 metres to the surface buoy

01:37:43

[Prof. Ravindran] from there through satellite communication to our [Prof. Idichandy] Satellite.

01:37:45

standard data buoy system, we are able to. So, we have made

01:37:48

4 such system and installed on the Arabian Sea

01:37:51

because that is the direction in which the most of our tsunami

01:37:54

[Prof. Ravindran] waves are coming periodically. [Prof. Idichandy] Tsunami is likely to have.

01:37:56

So, apart from US, we are

01:37:58

the only country manufacturing these devices.

01:38:01

I think you have tested some of them also the

01:38:03

[Prof. Idichandy] Yeah. [Prof. Ravindran] pressure sensors.

01:38:04

So, I had - NIOT has proven capability to prove this

01:38:08

special equipment in deeper waters

01:38:10

[Prof. Ravindran] which was never there in our country. [Prof. Idichandy] Yeah.

01:38:12

We - they were all imported.

01:38:13

So, we are slowly indigenizing this capability.

01:38:18

[Prof. Idichandy] In fact, you know, it's a totally unexplored area

01:38:22

with not much information, not much technology,

01:38:25

but I think anybody has, can be proud that

01:38:28

especially you can be so proud that

01:38:30

you could achieve, you know;

01:38:32

most of these things in a very very short time.

01:38:36

It is not that - and with very limited resources.

01:38:39

[Prof. Ravindran] Yeah. That too, that's right. Yes. [Prof. Idichandy] I think that is the - you know.

01:38:42

That is true; also in addition to this

01:38:44

in deep sea technologies, we are also we are providing

01:38:46

special benefits like you know,

01:38:48

we also have biotechnology-related activities.

01:38:52

For fishermen we gave technology of lobster

01:38:56

[Prof. Idichandy] Yes. [Prof. Ravindran] being grown in cages in 2 metre water depth.

01:39:00

[Prof. Idichandy] Yes. [Prof. Ravindran] So, they don't have to go into deeper waters and

01:39:02

be demonstrated in - we gave technology to

01:39:04

fisherman in near Thoothukudi, Tharuvaikulam, Erwadi, and all that.

01:39:09

We give them baskets which will survive the waves and currents.

01:39:14

So, it is in 2 metre; people can walk or they can

01:39:18

go and pick up this. It is like a bank you know where

01:39:21

these lobsters are there. Whenever you need money,

01:39:24

go and be - sells per kilo 800 rupees, 1000 rupees

01:39:28

those days, before 10 years.

01:39:30

So, people have - can save diesel, but only thing is

01:39:35

they come in - grow easily in shallow - clean waters.

01:39:39

[Prof. Idichandy] Yes. [Prof. Ravindran] So, unless people maintain clean

01:39:42

beaches we cannot grow lobsters or mud crabs.

01:39:46

[Prof. Idichandy] Ok. [Prof. Ravindran] So, this technology also we have developed.

01:39:48

Now, we are working on medicine

01:39:53

from the sea that is biodiesel also.

01:39:55

These are many activities. Now, new technology, now,

01:39:58

we have ventured into is that

01:40:01

the aquaculture farm land is polluting the land you know,

01:40:04

[Prof. Ravindran] they are losing the coastal aquifers. [Prof. Idichandy] Yeah, yeah.

01:40:07

So, now, like Norway has done,

01:40:09

we go into the deeper sea, put huge cages.

01:40:13

[Prof. Idichandy] Yeah. [Prof. Ravindran] 10 metres, 20 metre diameter cages and

01:40:16

50 metres high and grow fishes there,

01:40:20

big fishes which go up to 30 kg, 50 kg.

01:40:24

[Prof. Ravindran] We have already done this in Mandapam and Andaman area. [Prof. Idichandy] I see, Ok.

01:40:29

And we have demonstrated about 12 kgs.

01:40:31

So, now, this is going to be a major blue water economy

01:40:34

for our country, that, you know, we like to develop

01:40:38

this offshore fish farming technology which was never existent.

01:40:41

[Prof. Idichandy] Yeah. [Prof. Idichandy] So, that for that you know we need lot of

01:40:44

mechanical design like, you know, offshore designs

01:40:47

[Prof. Ravindran] of these cages which would survive [Prof. Idichandy] Survive.

01:40:50

in our monsoon weather conditions.

01:40:52

So, moorings, feeding devices,

01:40:55

so, really, even though its a fishes related,

01:40:58

[Prof. Ravindran] it is a interdisciplinary technology. [Prof. Idichandy] Yeah.

01:41:01

So, that actually also has come up and

01:41:03

[Prof. Ravindran] we have put a office in Andamans [Prof. Idichandy] Yeah.

01:41:07

to study the island environment and give them support,

01:41:12

survey into lot of other engineering work which, of course,

01:41:15

Ocean Engineering Centre also is doing - so, like that -

01:41:17

but most of the projects are

01:41:20

engineering-oriented, not stop with R and D. Provide a -

01:41:24

[Prof. Idichandy] Yeah. [Prof. Ravindran] solution to a problem in which we can harvest the

01:41:27

resources from the sea: either it is energy or food

01:41:33

or save the people from natural hazards.

01:41:35

[Prof. Ravindran] Hazards. [Prof. Idichandy] Like hurricanes, tsunami.

01:41:38

And then keep a complete warning system for monsoon protections.

01:41:43

[Prof. Idichandy] Yeah. [Prof. Ravindran] So, these are all the services being

01:41:45

[Prof. Ravindran] offered. [Prof. Idichandy] No, there is something very unique about

01:41:47

NIOT that... it is not just the R and D alone but

01:41:51

[Prof. Ravindran] Yes. [Prof. Idichandy] you always demonstrated in the industry.

01:41:55

[Prof. Ravindran] Yes, that is the thing, no? [Prof. Idichandy] Yeah.

01:41:56

[Prof. Ravindran] Unlike NIO, you know, people have studying for research's sake. [Prof. Idichandy] Yeah.

01:42:01

They study about the oceans, understand oceans,

01:42:05

but we do engineering projects for the benefit of the people.

01:42:10

So, that is the difference.

01:42:11

So, we need lot more people but we need support.

01:42:14

[Prof. Idichandy] In fact, there is something which [Prof. Ravindran] That support is not yet coming.

01:42:16

[Prof. Idichandy] Yeah that. [Prof. Ravindran] Large numbers.

01:42:18

[Prof. Idichandy] Ocean, if the - if the - it is something which is totally neglected.

01:42:25

[Prof. Ravindran] Yes. [Prof. Idichandy] In fact, we don't even have sufficient data.

01:42:29

[Prof. Ravindran] Yes. [Prof. Idichandy] Only after, you know,

01:42:31

[Prof. Ravindran] Yes, yes, yes. [Prof. Idichandy] the data buoy is

01:42:32

[Prof. Ravindran] Yes, yes. [Prof. Idichandy] collecting data only we have something like

01:42:36

you know, some data is available at this - so, right from that...

01:42:40

[Prof. Ravindran] Yes, yes. Even fisheries not fully exploited. [Prof. Idichandy] Yeah.

01:42:42

There is a joke saying that you know: one -

01:42:44

Indian waters' fish die of old age because they are never caught.

01:42:48

Yes, because we don’t have deep sea fishing trawlers.

01:42:52

[Prof. Ravindran] We don’t have deep sea fishing harbours. [Prof. Idichandy] Yes.

01:42:55

That - that is a policy lacking, lacuna there.

01:42:59

[Prof. Idichandy] Yes. [Prof. Ravindran] for deep sea fishing.

01:43:01

[Prof. Idichandy] It's a - it's a big tragedy, I mean.

01:43:03

[Prof. Idichandy] And - [Prof. Ravindran] Recently there was a conference of one forum

01:43:07

called Forum for Integrated National Security

01:43:13

for the country organised by- supported by

01:43:16

Ministry of HR Affairs and Norway,

01:43:19

and there we are talking about ocean security.

01:43:21

See, we are working now all over the place

01:43:22

[Prof. Ravindran] our ship goes all over the place. [Prof. Idichandy] Yes.

01:43:24

Now, Chinese are watching;

01:43:25

wherever we go Chinese are behind us.

01:43:28

We have to provide security.

01:43:30

[Prof. Ravindran] How are these offshore activities safe [Prof. Idichandy] Yeah.

01:43:33

from these people? People have totally

01:43:36

[inaudible] the threat coming from deep sea.

01:43:39

See, when you go on deep sea mining,

01:43:41

[Prof. Ravindran] you're 2000 kilometre away from coast. [Prof. Idichandy] Coast, yes.

01:43:44

Any health emergency, we don’t have support.

01:43:46

Any threat, security threat, we don’t, so.

01:43:48

So, in some of the ships, we carry gunmen,

01:43:51

hired from abroad, paying through our nose.

01:43:54

So, that's aspect also is not been taken seriously,

01:43:58

so far by Government of India. Now only they are talking about it.

01:44:03

So, we have 7000 kilometres of coast, how are we protecting them?

01:44:07

[Prof. Idichandy] And the huge area. [Prof. Ravindran] Like the 26-11 disaster

01:44:09

[Prof. Ravindran] can take place anytime. [Prof. Idichandy] Yes, correct.

01:44:12

How are we protecting?

01:44:13

So, we should understand oceans,

01:44:15

how do we protect our coast?

01:44:17

Not only look for resources,

01:44:19

how do you protect this science and technology activities?

01:44:22

[Prof. Idichandy] Yeah. [Prof. Ravindran] Resource harvesting activities.

01:44:25

[Prof. Idichandy] Great wealth - wealth is, you know,

01:44:26

[Prof. Idichandy] Lying below. [Prof. Ravindran] Lying below, yeah.

01:44:28

First, we don’t know we don’t know how to protect them.

01:44:30

[Prof. Idichandy] Yeah, that's correct. [Prof. Ravindran] Others are harvesting.

01:44:33

[Prof. Idichandy]I think it should be a complete policy change is required...

01:44:36

[Prof. Ravindran] Yes, the ocean technology needs much more investment

01:44:39

[Prof. Idichandy] Yeah. [Prof. Ravindran] and in terms of finance and manpower.

01:44:44

[Prof. Ravindran] I think - till the Ocean Engineering Centre was, nobody knew what was oceans.

01:44:47

[Prof. Idichandy] Correct, yeah. [Prof. Ravindran] Nobody knew what was offshore structure even.

01:44:49

[Prof. Idichandy] Yes. [Prof. Ravindran] So, Ocean Centre was the beginning

01:44:53

but a small group - we are doing within the

01:44:56

institutions and doing consultancies but

01:44:58

this set of activity, 2000 kilometres away: we need institutions,

01:45:03

we need infrastructure like big ships, standby ships, helicopters.

01:45:07

See, we go to Antarctica, we take 2 helicopters with us.

01:45:11

But when you go to CIOB which is also far away

01:45:14

it is 20 days journey, we don't take helicopters.

01:45:18

We take all of the risk.

01:45:20

So, we need investment, we need more ships,

01:45:22

more supporting systems, more manpower.

01:45:26

Another more important is: the policy making.

01:45:30

[Prof. Idichandy] Yeah. [Prof. Ravindran] Officials.

01:45:31

[Prof. Idichandy] That is - [Prof. Ravindran] They don’t understand oceans.

01:45:32

[Prof. Idichandy] Yes. [Prof. Ravindran] More important, we do not teach anything to our school boys.

01:45:35

[Prof. Idichandy] Exactly. [Prof. Ravindran] In one of the colleges, we asked: how are the

01:45:38

waves made - we are creating awareness about ocean,

01:45:41

we just asked, how do you get waves?

01:45:44

Ships are moving, so we get waves.

01:45:46

This is the knowledge of people about waves.

01:45:48

Nobody knows, even the teacher,

01:45:51

school teachers do not know about oceans.

01:45:53

[Prof. Idichandy] So, it's a - [Prof. Ravindran] So, we have to have a awareness

01:45:55

[Prof. Ravindran] even at the school level [Prof. Idichandy] School level.

01:45:56

about the oceans, then only

01:45:58

[Prof. Ravindran] our officials will know what oceans are. [Prof. Idichandy] Yeah.

01:46:00

So, that's why I said

01:46:01

way forward is to educate our policy-making bodies:

01:46:05

[Prof. Ravindran] officials and ministers. [Prof. Idichandy] Yeah, I think it should start in the school itself because

01:46:08

now there is absolutely nothing.

01:46:10

You know, when a student, 12th standard, when he passes, you know,

01:46:13

I do not think he knows anything about ocean.

01:46:14

I was telling you, this engineering college student said

01:46:17

waves are made by ships, so, like...

01:46:21

[Prof. Idichandy] Ok. I think, I know you can go for hours

01:46:23

[Prof. Ravindran] Yeah. [Prof. Idichandy] talking about NIOT and its programme.

01:46:27

Why did you suddenly decide to say...

01:46:34

[Prof. Ravindran] Yeah. [Prof. Idichandy] That is a.

01:46:35

I was 60, even though there was a request both

01:46:38

by Dir - you know, Professor Ananth came and

01:46:40

requested me to come back as a Professor Emeritus,

01:46:42

you made a request formally, Government of India

01:46:44

also said that. I said the last 12 years of

01:46:51

NIOT, it was a tremendous work, even my wife

01:46:53

was complaining that I don't have time even to talk to her.

01:46:57

[Prof. Idichandy] Ok. [Prof. Ravindran] Really, I used to travel so much,

01:46:59

day night spending the time.

01:47:01

So, she said, let us do something other than technology.

01:47:07

[Prof. Ravindran] So, no more coming to a permanent institution. [Prof. Idichandy] Ok.

01:47:10

So, at that time, we were starting a

01:47:13

parallel activity of social service to a

01:47:17

[Prof. Ravindran] tribal community in Dharmapuri district in the reserve forest. [Prof. Idichandy] Ok.

01:47:22

So, with our doctor friends, we were trying to establish a hospital.

01:47:26

They needed manpower, not only money,

01:47:29

but they needed people to work with them.

01:47:31

Even though they were willing to stay,

01:47:32

but they need lot of support to collect money,

01:47:35

get some approvals, construct the hospital,

01:47:37

bring equipments and bring people administratively.

01:47:41

So, we said we'll go and help them.

01:47:43

And I was also working with Gandhigram,

01:47:45

[Prof. Ravindran] designing small small machines for them [Prof. Idichandy] Yeah.

01:47:47

[Prof. Ravindran] for minimizing the manual effort of rural ladies

01:47:52

who are working in some of our

01:47:54

[Prof. Idichandy] Ok. [Prof. Ravindran] spinning, weaving, and ayurvedic medicine preparations,

01:47:58

soap-making, etcetera. So, I thought I would spend more time,

01:48:01

something different and then spend more time with

01:48:04

the family because I - which I never was able to spend

01:48:06

right from the day 1 - heavy work you know,

01:48:09

in the Turbomachines Laboratory, see

01:48:11

[Prof. Ravindran] I was in charge of major fabrication erection. [Prof. Idichandy] Yes.

01:48:14

And my PhD also was very [inaudible] and then

01:48:16

Ocean Engineering Centre was also a tough [inaudible]

01:48:18

erection, lot of facilities, when we came, in NIOT,

01:48:22

totally different work. So, I started to spend more time.

01:48:27

Went home, and then spend time with these people

01:48:29

where you see immediate benefit, where ocean technology

01:48:33

has got lot - time-relevant for

01:48:36

success. Lead time is there;

01:48:37

[Prof. Ravindran] Yeah. [Prof. Idichandy] Even after 2 years we don't see this.

01:48:39

[Prof. Idichandy] Correct. [Prof. Ravindran] Somebody whereas, here instantly within few weeks,

01:48:43

few months, teaching the small kids who are school drop-outs

01:48:47

doing something with their own hands:

01:48:48

repairing a motor, repairing a pipeline, water pipeline, welding,

01:48:53

[Prof. Idichandy] Yeah. [Prof. Ravindran] constructing, we have trained small kids to build -

01:48:59

[Prof. Idichandy] Masonry work. [Prof. Ravindran] masonry work with compressed bricks without any cement.

01:49:03

[Prof. Idichandy] Yeah. [Prof. Ravindran] You should see the hospital

01:49:06

and the guesthouse building which they have built.

01:49:08

The kids whom we have seen with 15-16

01:49:12

we have taught them and - and they have built -

01:49:14

they have become masons.

01:49:15

So, that really, it's a real

01:49:18

[Prof. Ravindran] happiness which we - [Prof. Idichandy] That is a different type of satisfaction you know.

01:49:22

[Prof. Ravindran] Yes, [inaudible]. [Prof. Idichandy] Nothing like -

01:49:25

And then we gave our small machine to decorticate groundnut,

01:49:28

at sometimes they used to, they used to sell cheaply

01:49:30

[Prof. Ravindran] because they cannot process them. [Prof. Idichandy] Yes, yes.

01:49:32

So, post-harvesting using machine. So, when we gave the one

01:49:35

we can see the happiness in the whole village

01:49:40

that now they are able to use

01:49:41

that groundnut because they are able to decorticate,

01:49:44

they can make chutney, they can make sweets,

01:49:47

they can go and get it crushed, and make oil,

01:49:50

they don't have to sell as a raw material

01:49:52

to somebody who sells the -

01:49:53

brought it back to them at a 3 times cost.

01:49:56

That you know is something - capability building.

01:49:59

Now, the people whom - fellow who did not know

01:50:01

how to speak English or anything is the electrician for the EV.

01:50:05

For the entire village.

01:50:08

We have taught them how to rewind motors, how to repair pumps,

01:50:12

how to lay pipeline, now all hospital: our wiring,

01:50:15

everything is done by these kids whom we have trained.

01:50:19

And in fact, the skill development, you know, it's a

01:50:21

mission of the Central Government; it should happen like this,

01:50:25

I mean, at the - at the grassroot level,

01:50:27

you go there and stay with them and then teach them.

01:50:30

So that, you know, they are independent and they

01:50:34

don't have to depend on anybody else.

01:50:36

So, I would like to tell you something very - my bad experience

01:50:38

with so-called skill development of tribals.

01:50:41

I applied for the project with Ministry of Science,

01:50:44

they have special money and lot of money.

01:50:47

We said: this is what we want to do,

01:50:49

this school dropout kids, we want to train and

01:50:51

we want welding machine, a lathe, and these things,

01:50:54

and a small dormitory because they walk down from hills,

01:50:57

they cannot go back, they will be with us at least for 3 months.

01:50:59

[Prof. Idichandy] Ok. [Prof. Ravindran] So, we want to give them some food and shelter.

01:51:02

Yeah, dormitory accommodation: you know, the committee

01:51:06

of Science and Technology came: Sir, you are a professor from IIT,

01:51:10

why are you asking for such low-grade equipment

01:51:14

like lathes and welding machine?

01:51:16

You ask for project with [inaudible] we will give you

01:51:18

because we know you - you are not going to stay there.

01:51:21

You will go - something will -

01:51:22

I said, I have a house, I have a commitment to live with them.

01:51:25

You come and see my house there. People said no.

01:51:30

I told the then secretary: no,

01:51:32

I said something is wrong with your approach to the tribal.

01:51:35

They have a training fund; skill-development fund.

01:51:38

I was asked to submit a project.

01:51:40

After that the expert committee ask these questions.

01:51:44

I said: I don't want your money.

01:51:47

I want only if you give me. I am not

01:51:48

something, any another project - that was my personal experience.

01:51:52

So, we don't get anyway;

01:51:53

all this effort is done by private money.

01:51:56

There is no government and their money or

01:51:59

Government of Tamil Nadu money, you know.

01:52:00

[inaudible] worked with tribals, even the lot of

01:52:03

[Prof. Ravindran] projects. [Prof. Idichandy] Is there any appreciation from either the government or?

01:52:08

[Prof. Ravindran] Government? No. Government, there is no appreciation,

01:52:11

but lot of other agency which recognize us,

01:52:13

they are give us some awards here and there.

01:52:18

Now, we because we also do organic farming

01:52:20

[Prof. Idichandy] Ok. [Prof. Ravindran] with certification.

01:52:22

So, that's a, even in hills where there is no rainwater

01:52:27

we have to keep them to grow millets and

01:52:29

you know post-harvesting machines; that is

01:52:33

what we want - they stopped worrying because

01:52:35

they could not do like millets, they cannot dehusk them.

01:52:39

They are very hard.

01:52:40

So, we have a small small machines to dehusk them.

01:52:43

And we mark it down further.

01:52:46

So, that way you see the - in the last 20 years,

01:52:50

the tremendous development has taken place in that village,

01:52:53

among women we taught them embroidery.

01:52:59

You do at home and then earn

01:53:00

[Prof. Ravindran] 100 rupees more from embroidery. [Prof. Idichandy] Oh.

01:53:05

Women at home; empowering women

01:53:07

[Prof. Ravindran] it's really the empowering women. [Prof. Idichandy] Yeah.

01:53:09

Then we have these people, we give them free

01:53:12

as - because we collect many 100 rupees from each individual,

01:53:15

[Prof. Ravindran] give them 1 year of free medical help, both [Prof. Idichandy] Ok.

01:53:20

inpatient, outpatient, all medicines free, 100.

01:53:23

[Prof. Ravindran] Just to make them to come to hospital. We have nearly

01:53:27

40 bed hospital with extremely good facilities,

01:53:31

with all facility, ECG, this thing, monitoring, everything.

01:53:35

It is much better than a district hospital in the middle of the village.

01:53:41

And we run a school now for the staff children.

01:53:45

[Prof. Ravindran] They said [Prof. Idichandy] Ok.

01:53:46

our children must speak English like you.

01:53:49

They were kids when we started the hospitals,

01:53:51

when we trained them, the girls, you know

01:53:53

all our nurses are only local girls, tribal girls.

01:53:56

[Prof. Ravindran] Our doctors have trained them. [Prof. Idichandy] Ok.

01:53:59

And now the children are grown up

01:54:01

and [inaudible], built a school for them, teach them English.

01:54:07

[Prof. Ravindran] We are doing that. That is happiness. [Prof. Idichandy] Okay.

01:54:11

[Prof. Idichandy] Great, with Professor Ravindran, we have been on a

01:54:14

very long journey in small 1 hour;

01:54:19

I don’t know how many minutes we have taken about 100 minutes.

01:54:23

[off-camera] Yes. [Prof. Idichandy] Or little above that.

01:54:24

[off-camera] Yes yes. [Prof. Idichandy] I am sure that this message will go to many many

01:54:31

people once it comes out as a project of the

01:54:36

Heritage Centre of IIT Madras.

01:54:38

I hope some of the remarks that you have made

01:54:40

reaches the people to whom it is meant and

01:54:45

with that note let me take -

01:54:48

Thank you very much.

01:54:49

I think, thanks for your time and I think I'll thank the Heritage Centre,

01:54:53

Mr. Kumaran and Mrs. Mamata for the

01:54:57

effort they are taking to talk to the alumni and faculty together.

01:55:03

[Prof. Idichandy] Senior people. [Prof. Ravindran] Senior people who have spent a lot of time

01:55:06

[Prof. Ravindran] to get a feedback of their experience. [Prof. Idichandy] Yeah.

01:55:10

Now and then. Make it public, I think,

01:55:13

[Prof. Ravindran] if people I think they have been, yes. [Prof. Idichandy] Yeah, I am sure it will go.

01:55:16

I think, I have said lot of things, they are purely my opinion.

01:55:19

[Prof. Idichandy] Yeah. [Prof. Ravindran] Not meant to hurt to people, but my personal feeling

01:55:23

because we have worked so much: 50 years in this business

01:55:25

of education and technology.

01:55:28

So, certain times, you know, I used to really get frustrated

01:55:31

because of somebody not supporting, not understanding.

01:55:35

So, whatever I said is because of that frustration,

01:55:38

but it is not meant to hurt anybody,

01:55:40

[Prof. Ravindran] but really, I - what. [Prof. Idichandy] No, I think whatever you have said will be

01:55:44

taken in - in the - true spirit of it.

01:55:46

But I am really thankful to, really, my career growth

01:55:50

opportunities, especially the final great opportunity of NIOT came

01:55:55

[Prof. Ravindran] because of my association with IIT Madras [Prof. Idichandy] Yeah.

01:55:58

Ocean Engineering Centre because I never expected

01:56:01

that I become a Ocean Engineer,

01:56:04

and especially my association with Professor Scheer

01:56:08

in Turbomachines Laboratory,

01:56:09

the support, given on the training [inaudible] so.

01:56:14

And that has helped me in other parts of life, you know,

01:56:16

you became a better overall well-rounded person.

01:56:19

And then, we are able to help people.

01:56:21

So, the hands-on experience, everywhere helpful,

01:56:24

[Prof. Ravindran] either in our rural technology or hospital [Prof. Idichandy] Ok.

01:56:28

or Ocean Technology, we able to see through a

01:56:31

wide spectrum of activities because of that

01:56:34

great experience from IIT Madras.

01:56:36

[Prof. Idichandy] I thank - [Prof. Idichandy] Ok, I think one thing I forgot is

01:56:39

[Prof. Idichandy] asking something about the family, yeah.
