Dear Michael
My experience of that stove is that it produces nearly no char at all which is why the fuel efficiency is so good. It also happens to have low emissions. Char can only be made from raw fuel. In the Eastern Cape there is a serious fuel shortage and many people have to cook with dung in desperation. Regards Crispin Do these stoves produce any biochar?
