This seems like a pretty good tutorial on how to make a small stove. I don't have any experience with stoves but according to this video if you had one gallon of denatured alcohol it would last for about 22 hours of cook time. What do you guys think? Could something like this be done with a old stainless steel thermos? It seems like a SS thermos would hold up longer than a coke can would. Do the times seem pretty good for one ounce of fuel or can you get better performance with a store bought stove? I like the idea of using so many different fuels in a stove like this.
