Ron,
Thanks for the report.
I would be interested in reading your presentation, "Specifying Stove
Performance in Climate Terms".
Interesting to read about the "emphasis on China" that Dean refers to...
and that ~1800 or so Stove manufacturers in China might be making
"gasifiers"... that could also possibly be producing Biochar.
