[Terrapreta] Village or Household scale Charcoal/Wood gas production

[Gary Frase]

I have only just bumped into these ideas which I can see have immense potential for the poor farmers of the world who are actually most of us.  I get the impression that many around the world are working in this direction, and that likely many have come up with simple small scale apparatuses that can make this technology readily available to the people who need it desperately.  I'd like to hear what others are getting to.  Thanks, Gary Frase, USA
