The wood gas stove

So this thing is pretty sweet. Fairly small, no fuel needed. You stuff it full of sticks, then through in a fat stick and light her up. Once it gets to the right temp the real fun starts. There is no oxygen in the bottom, just intense heat. The heat breaks down the wood into the flammable gases which rise and mix with the oxygen coming in the holes and ignites. All the ash, particles and smoke that normally fly up when wood combusts just stay nicely in the bottom. It has a fan (powered by double As) that has two speeds to increase the flow of oxygen to the holes on top which really heats up the burning of the gases, but if there is a bit of a breeze it actually works very well without the fan. With the heat transfer coil pot (the jetboil one) it boils water super fast, and with no smoke in your face nor ash flying around in your food. And you never have to worry about fuel. This one is pretty big, but I think they have smaller ones, and I have seen designs to make your own out of 2 tin cans. Pretty sweet.
