[Stoves] the price of bottled gas

Sun May 5 13:11:20 CDT 2013

Was there not in Kenya that Cornell University test project... biochar, and
liquid fuel, from biomass with really small scale production. I wonder if
that worked well... and would it easily produce also gas that could be used
to refill those small gas bottles ?
