Re: Cool idea for a camp stove
Those are pretty cool and work well. I have a friend who hiked the CDT, and when they were preparing and figuring out what gear to take he experimented with a stove like this. We referred to them as "penny stoves" as there was a penny on top of a flat burner with holes in it that regulated the pressure in the stove. A few of us built them and had contests of who's custom design would run the longest. Ultimately he decided they were not efficient enough for a through hike.
But definitely a cool and fun thing to build and have!
