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.
