Actually, I do have a catalytic propane heater. I'm just intrigued by this backwoods sort of coffee can heater device. When I was in Desert Storm back in '91, we used to mix diesel and sand together in a coffee can, then ignite it to heat up water or whatever. Was very sooty though.

I had an alcohol stove on my boat once. That 'lil stove was a hot little burning device...
