I just built my first beer can stove and it seems to work well (although, I've never used one before this). It brought 16oz of tap water to a roiling boil in 6 minutes in 25-30 degree weather, then burned another 3 minutes with 1 oz of Heet. It weighs .25 oz, and the windscreen/pot support is another .5 oz.
It seems this is fine for boiling water, but what if we catch a fish or two? Has anyone cooked (rather than boiled water) with an alcohol stove? Particularly a beer can stove?
This is the one I built...
Thanks for your comments/suggestions...
