Biochar

OK here it tis=biochar farming :)back t firing kilns like when I made pottery but instead of clay=we will fire biomass mmm=could get gas exploisons I hear but I am lookin foreward to those hahah :) All joke aside=biochar farming could be the answer for small sustainable communities who dont have a lot of soil or space. The biomass needs to be fired to around 500-600c with total reduction=no 02.
