In the aftermath of a natural disaster such as an earthquake or tornado, there will probably be a lot of biomass and wood debris laying around. Suppose you have to boil water or cook, using whatever materials are available.
If you can salvage some bricks, you can make this stove. It is simple to build, and is easily fueled with bits and pieces of wood debris or biomass. It is sturdy, so the top will hold heavy pots and pans easily. It is also very fuel efficient, and works under a variety of challenging circumstances.
