Build a Super Efficient, Portable Wood Burning Stove

If you're looking for a cheap, efficient stove you can take camping, William Abernathy at Make can show you how to make one out of an aluminum can.



Abernathy uses a never-filled, 1-quart paint can for his design, and you can make it with just a can opener, punch, and a rock. Using just a handful of scrap wood, the stove creates enough heat to easily boil a pot of noodles or some tea. Abernathy describes how it works:



This TLUD [top-lift updraft] stove works in batches: fill it up with twigs and woody bits, and light it from the top. As the fire burns, it makes a layer of hot coals, and as this burning mass descends into the can, it becomes starved for air. Enough oxygen comes up from below to keep the embers alight, but not enough to sustain a flame.



We've shown you how to make a simple camping stove before, but this one uses wood scraps and twigs for fuel as opposed to alcohol. This stove is incredibly efficient because it practically sustains itself on the ashes and gases its producing. The ashes recirculate after primary combustion and stay lit like charcoal. The flammable gases created in primary combustion rise to the top to combine with preheated air and cause a secondary burn that consumes some of the methane, soot, and carbon monoxide leftover.

It's important to note that you should not use one of these indoors, as it produces carbon monoxide. The stove will also get very hot, so do not use it on any wooden surface or it will burn a ring into it. Your best bet will be a dirt patch with no vegetation nearby or a rock.
