Paul, Point taken. My goal is to promote the idea of the value of using biomass other than wood as stove fuel. I see this as a strong point of pyrolytic stoves and a dis-advantage of simple combustion stoves. As many have pointed out, this advantage is generally greatly under-valued. I believe that pyrolytic stoves, such as TLUDs, should get credit where credit is due, especially as this is a key point of differentiation between the two approaches.
