You should try a "Cat-Stove." Tis made out of a cat-food can and a tuna can. You should be able to find plans for it on the net. I use one. They are supposed to be the best. I had a cook-off, against my propane stove, and it beat my propane stove.

They are easy to make and the only thing that you need is two old cans and some insulation.
