Dear
Prof Chakravarthy,
From
IIT –B web site , I found that you worked for L&T (
Switchgear design ? ) between 1988 -94
I
too worked for PSW from 1959-71 and then moved onto Madh / Central
Personnel / GM-Powai and moved to L&T house in 1988 as GM ( Planning ) ,
before retiring in 1990
From
some article , I learned that you guided Avinash Prabhune in design of a Solar Cooker
In
this connection , I thought you might like to look up my following blog
With
regards,
Hemen

Solar Chulha : Where can I buy ?
On 3rd Nov 2017 , ONGC came
out with a half page advt , inviting public to :
“………come up with innovative ideas to design and develop “ Solar Chula “
[ See
original Advt at :
Not finding in that advt or
on ONGC web site , any “ Specifications “ for that
chulha , I sent following email to ONGC [ cmd@ongc.co.in ]
Solar Chula ?
Some Unanswered Questions [ 03 Nov 2017 ]
Extract of
my Email :
Nowhere
on the web site , there are any SPECIFICATIONS ,
against which ONGC will
carry
out those “ Performance Tests “ to decide “ Successful
Demonstration “
In total absence of
any SPECIFICATIONS , will this ( ONGC ) expensive / time – effort
consuming exercise boil down to , “ It is MY word against YOURs “ ?
Hence , the
SPECIFICATIONS for Solar Chulhas would need to be :
# Chulha should be capable
of cooking a meal for 4 persons ( will need to sharply
define “ MEAL “ ) , in 30 minutes , solely drawing its power
from a SOLAR
POWER
STORAGE device , which collects / stores solar power , from solar panels
mounted
on the terrace / roof top .
Solar
Storage Device should have adequate storage capacity for cooking 2 meals
before needing re-charge and should be capable of being re-charged
from
standard 210 V / 5 Amp domestic electric outlet
# Chulha should be
of XYZ dimensions , for easy accommodation inside a kitchen
# Chulha should not cost more than Rs
10,000 / - to manufacture ( which
would be
excluding the cost of SOLAR POWER STORAGE device )
# ONGC will not have any IPR ( Intellectual Property Right )
for the winning designs
, which will vest in the INNOVATOR .
However
, the innovator would be required to license any party / person for the
manufacture , without any licence fee / royalty
Apparently , my email did
have some effect , since ONGC , later on ,
came out with the following “ performance
features“ on its website :
1. The broad performance features
expected from Solar Chula among other things
include
:
i. Solar
Chulha should work on solar energy ( solar thermal or PV )
or any other
renewable
energy as source of energy which can be easily accessed or made
available
in any house hold kitchen.
ii. It
should be possible to keep the chulha all time inside
the kitchen for cooking
purposes (
including frying, baking and chapati making ), similar to traditional
commercially
available cook stoves which work on LPG or other fuels.
iii. It
should be possible to use the Solar chulha on need basis any time
during the
Day / night ( 24X7 ) basis.
iv. It should be
suitable for built up of materials which are easily available and can be
disposed safely and can be mass produced
with economies of scale.
v. It can be used
independently or in conjunction with the grid, as the case may be.
vi. The solar
chulha must meet safety requirements for use in any house hold.
vii. It should be
able to provide sufficient meals for a family of five.
During the night time
it will work on
stored energy with energy storage, having a life of around 2500
cycles.
2. The estimated cost of the solar chulha
along with the energy source preferably
not
exceed Rs. 10,000/- per unit. ( For a volume of few lac units ).

Dear ,
Shri Dharmendra
Pradhanji ( min.png@nic.in / d.pradhan@sansad.nic.in )
Shri Shashi Shankerji – CMD -
ONGC ( cmd@ongc.co.in )
At the outset , hearty
congratulations on this initiative having a revolutionary potential
This solar chulha is the
answer to save the lives of millions of women in rural India
It is possible that private
sector industries may not think of getting into the manufacture / distribution
of this product , since it may not be adequately profitable
But , if government can give
subsidies for Electric cars ( FAME ) and Electricity connections to villages (
SAUBHGYA ) , then why not for Solar Chulhas ?
Would that not be far better
than giving subsidy for LPG ?
Of course , the opposition
will cry : You are trying to bribe village women for 2019 !
Please ignore them
They don’t have to worry
about crude oil price crossing $ 100 / barrel !
