[Stoves] Request for technology proposals - Clean Stove Initiative, Indonesia

[Frank Shields]

Dear Ron, 

 

I believe the approach you are taking is wrong and likely to go nowhere.  

 

When boiling water there are lots of waste products from the process: Smoke
and tars, char, ash and left over biomass too small to re-use. 

When making Biochar to add to a soil there are waste products:  gases that
are flared off, ash etc.

 

All are waste products because they are not used for the intended purpose or
product and, before they can be used for something else they need to have
the quality suitable for that purpose. 

 

I think it is good enough to just market a stove for 1) boiling water or 2)
boiling water and produce char for possible other purposes. If the char is
something someone will be able to use they will buy the stove that gives
that added benefit. They can sell it or use it should it have the right
properties. There can be no addition to the formula. There is no winning or
losing.  Just marketing. But we need to make sure it is mentioned char is
produced. 

 

AND I am not so sure the efficiency of a Rocket is all the better than the
TLUD when the right formula is used (E450c). : )   Should the TLUD be
slightly less efficient than the Rocket I think marketing for char will take
it to the top of the list of preferred stoves. 

 

Regards

 

Frank

Crispin:

 

            I think TLUD companies might find it interesting to enter on the
water-boiling side of this RFTP.   But it is not clear how charcoal will be
counted.  I can see at least three formulas for calculating the efficiency;
one ignoring the char, by which no TLUD could ever win if they wanted to
save the char.  The two formulae that count char as a useful co-product
could either (or both) place the char in the numerator or the denominator.
One of these formulas will make the proscribed efficiencies quite
achievable.  I can't find the intended formula(e) in what you have sent.

Dear Friends

 

The RFTP has been placed on the GACC website at the following address:

 

 
<http://www.cleancookstoves.org/funding-opportunities/grants/request-for-tec
hnology-proposals-indonesia.html>
http://www.cleancookstoves.org/funding-opportunities/grants/request-for-tech
nology-proposals-indonesia.html

 

in a slightly shortened version to meet the space requirement.

 

Many thanks Barbara Kerr
