This is an interesting idea. Not sure what kind of a lifespan the stove might have....but if ammo cans are cheap.... There are also rocket stove versions of the ammo can stove....just google search them. Via: survival | Last Minute Survival Edit: There looks to be enough room for a two burner rocket stove...with fuel feed tubes from both ends. Perhaps the second rocket being of slightly smaller diameter...
Nice post @chelloveck .... ammo cans are indeed cheap... come in all sizes and are tough as nails... same concept and you can build yourself a nice portable forge as well....
Nice post and interesting ideas. I must admit my personal OCD tendencies made it hard to listen to him continually refer to a ".20 caliber" can instead of 20MM...
