my buddy just showed me how to make an alcohol stove from 3 beer cans. In 04 he hiked the entire AT in 6 months and ditched his whisper light and used the one he made for almost the whole time. He still has the same one and uses it all the time. It will boil a pot of water with about 2 oz of alcohol. It is very small, bomb proof, weighs almost nothing and uses any alcohol based fuel. Denatured, rubbing, gas line anti-freeze, even 151 proof rum. It has no moving parts, o-rings or lines to break, doesn't soot up pots, flare up or give off many fumes, so it's good for using in tent vestibules. It is what i will be using for my elk hunts.
