[Stoves] Gathering data on TLUD stoves was Re: Last? Alternative to Charcoal

[Paul Anderson]

Dear AD,

Below is the data for your stove.   It is GREAT for our discussions.

1.  Making a PROFIT from the charcoal means that the fuel is actually 
better than free!!!!   As long as the fuel supply is sustainable, this 
is BETTER THAN any consideration of fuel efficiency or energy efficiency.

2.  The emission of
> CO = 8.1 gm
> Particulate Matter = 69 mg
may or may not be excellent.   We do not know how to interpret those 
number when the cooking task was only stated as
> Emission Results    (for cooking 2.5 lit of food)
You can help interpret that, but until we have some uniform way of 
reporting and comparing, we only have non-comparable numbers. That is a 
big part of OUR problem (Our meaning all of us.)

Perhaps the agency that did the testing can help interpret the result.   
It that cooking task something standardized in India?

Thank you for your data of results.   It is not the same as providing 
the RAW data as collected, but it is progress.

Is there some Stover or Biochar Buff who would like to undertake 
compiling the results from TLUD stoves?
