[Stoves] "stove-acceptance" of char-making [TLUD] stoves.

[Paul Anderson]

Stephen,

Excellent.    Please note:   There is a major GACC stove meeting in 
Cambodia in March 2013.   Not much there about biochar, so it is 
unlikely that you will attend.   But I will be there and I (and others) 
would like to have your data / results about acceptance of "stoves that 
make biochar" (probably aka TLUDs ).   Please make every effort to make 
the results available in time.

If you need a person for discussions without using list serves (such as 
for commenting on drafts on a confidential basis), I volunteer or could 
help you find others.

Paul
