BioChar stoves

I got to see a demonstration of a Biochar Stove- which is very similar to a Rocket Stove, which I have made, but this one cam be used inside- providing you monitor for carbon monoxide. Biochar-producing stoves are potentially much cleaner, with lower emissions of carbon monoxide, hydrocarbons, and fine particles. Biochar-producing stoves have lower greenhouse gas (carbon dioxide and methane) and black carbon emissions, create biochar that can be used to sequester carbon in soils, and reduce the use of fossil-fuel based fertilizers. Don't know that I will make one, but Great news for TEOTWAWKI type folks. Also great for Disaster preperations
