A constant pursuit in backpacking is finding ways to lighten your load. One way you can do this is by getting your cooking fuel from nature as opposed to carrying it in all the time. In this video I demonstrate how to make a lightweight wood gas backpacking stove. This design has been around for a while and is constructed in such a way that causes the wood to reach a state of secondary combustion whereby the smoke / wood-gas is burned up due to the super-heated air flowing through the walls of the stove. This completely burns up the wood into a fine white ash afterward. It is incredibly efficient, puts out a lot of heat, puts out very little smoke, and saves you from having to carry liquid fuel in your pack.
One of the coolest things about this type of stove is that it takes very little fuel to boil 2 cups of water. And all of this fuel can be picked up right off the ground so long as the fuel is dry.
