I like gadgets. As a Scoutmaster I have the opportunity to go camping a lot. I don't have a stove.
So I built one.
I started looking into "pop can stoves" on them internets a while ago and decided to make one. My first attempt was mildly successful.
The basic theory is that you make some enclosure that will hold alcohol. This enclosure self-heats and the alcohol vaporizes and comes out of some holes or jets.
I used the bottoms of two pop cans. You fit one inside the other and poke some holes around the top one. Add a fueling hole and you're ready to go.
Well I want quite satisfied with my first one; it used too much fuel and wasn't very efficient. So I built a second one.
It looks nice, but the jets point out sideways too much, which expends most of the heat on the sides of the wind screen. Not ideal. But with fewer jets it burns much longer. Much more efficient than my first attempt even.
I'll make another one soon using a narrower diameter can (the new small Coke cans look perfect). Fiberglass inside seems to help moderate the flame a little, too.
