Demo of making biochar
The demo includes some interesting tidbits about the properties and uses of biochar. It's a little visually confusing because they show different stages of building the char-making unit but not in order of construction and use. Have absolutely no idea why they show it wrapped with insulation a couple times near the beginning of the video,when they don't show that later. Might have been part of one of their experiments.
One thing they found was that wood is _not_ one of the best things to char -- too dense. All those leaves one rakes in the fall in New England however, might have possibilities...
