Those are some neat looking stoves. I used to use a coffee can, when I was a kid, for a stove, when, some Friends and I went camping. Just a Coffee can with holes made with a "Church Key" (old style bottle opener, with can hole opener, for cans without pop tops, and juice cans.) around the bottom sides. Just fill it with whatever would burn.
My Brother showed me how, and then, I saw a show, that showed the Koreans, that lived outside of town, who lived in small huts, with a big hole in the ground under the hut, and during the winter, they stayed there, they heated it with a coffee can, with holes in the perimeter of the bottom, and then put tightly rolled up card board in it, and soaked it with kerosene, and it not only served as a cook stove, but as a very efficient heater. I have one of Eddies little stoves, and they are really neat, and very effective!
I still need Eddie to get the guy to show how he makes them. It is supposed to be a really easy method. But when it heats up, it comes out around the can, through the tiny holes, like little jets!
