[Stoves] Last? Alternative to Charcoal

Sun Apr 21 03:25:45 CDT 2013

Otto,

I agree fully with what you say here: Just bring the "Micro" kiln into the
kitchen and produce your own char while cooking".
While one cooks a meal, one makes biochar, and this biochar in many cases
has a greater value than the fuel put into the stove. Biochar in this case
becomes the economic driver behind cook stove technology. It allows many
poor people to earn money each time they cook a meal.

Thanks.
Paul
