The Army has a multi-fuel stove. I'm too lazy to look up the nomenclature, but we used it in Alaska. It burns straight gas, gas and diesel mixture, or straight diesel. In a pinch, it can burn wood too.

This is not a backpacking stove. It probably weighs about 25 pounds. Made to fit in a 10 man arctic or larger tent. It heated stuff up, not cooked it.

Gas worked the best, although you end up changing gas cans more frequently. Gas/diesel was pretty good, good heat, more burn time, at about a 2/1 gas to diesel ratio. Pure diesel sucked, took forever to get it going and then the heat output was poor.

No matter what you burned, clean up was a pain.
