Dear Crispin, Thanks for highlighting me on that issue.Is such a stove to complicatied or expencive for the low income households of Africa? If you put a natural draft gasifier in an enclosure to get the primary air prehated using dry fuel, I would guess that you could use fuel of higher moisture content, later on. I understand that very dry fuel might burn so fast, that PM might enter the indoor air.I also think a fan driven gasifier might speed up that process and make it even worse? Otto
