Youtube is replete with plans for these alcohol burning mini camping or emergency stoves. Given my interest in stoves, not to mention other gadgetry, I decided to have a look into this intriguing area. Needless to say, I was pleasantly surprised. I just made a very basic one, using the bottom inch or so of 2 Pepsi cans. For the "alcohol", I used gas line antifreeze. As a fuel, alcohol is relatively safe as it's not too volatile. However, once you heat it a bit and get it to vaporize, it burns with a roar not unlike that of a Coleman stove. I think I'll make a more deluxe model later.

place water on top
This was just a quick conceptual test, but I'm going to make a better one...more to come :)
