We've featured DIY wood gasifiers before, but this how-to video—created by survival and outdoors expert Paul Osborn of BCoutdoorsurvival—for building a miniature stove for backpacking purposes is about as good as DIY make-our-own videos get. Using little more than two tin cans, and a few readily available tools, you can build a stove that boils water in minutes for next to nothing.

Making the Wood Stove

(The ring of upper holes injects hot air into the top of the stove, essentially acting to reignite gases that would otherwise be wasted.)

The addition of a pot stand, also made from an old can, allows you to place a pot of water (or whatever) on top, and according to the video you can boil a few cups of water in 8 minutes or so. Pretty darned neat. I'd love to hear from anyone who has tried this.

Here's the full video (found via the ever excellent Permaculture Magazine), which you really need to watch to get the full details on how to build. Please be sure to also check out our other posts on how to build a rocket stove and a rocket stove water heater too.
