And if you bury the carbon char, work done in the amazon shows it stays in the soil for 1000+ years. (Get the carbon out of the air and into the soil.) http://www.eprida.com/hydro/yahoo2004.htm
I have been looking into this idea since I have accumulated piles of ivy and blackberry roots, upper portions and brush, small limbs and branches etc... I would rather make bio char than burn it. The contraptions that I have seen on utube and other internet sites either are small demos or sophisticated large equipment. I would love to see this happen in the willamette valley of central oregon where grass seed farmers burn debri after seed harvest. In HawaII where sugarcane debri along with plastic irrigation pipe go up in smoke. Another term used is pyrolysis. TE
