A Rocket Stove Made From a Five Gallon Metal Bucket
The principle behind a rocket stove is simple–rather than cooking on an open fire, you burn wood in an insulated chimney. Rocket stoves are highly efficient and easy to make. They run on twigs, so you can avoid cutting down a whole tree just to cook dinner. We’ve had a rocket stove made out of brick in our backyard for several years. The post we wrote on it in 2007 is–oddly–the most frequently searched post on this site. I figured that since there was so much interest in the topic it would be good to offer one that didn’t require masonry work. Using a piece of 4″ vent pipe and a 90º elbow, I made the chimney. I traced the outline of the vent pipe on to the lid of the bucket and cut this hole out with a jig saw. Using the vent pipe as a guide again, I cut out a 4″ hole near the bottom of the bucket. I used one part clay (harvested from the yard) to six parts vermiculite as my insulation material. I found a barbecue grill at Home Depot that rests on the top of the bucket to support a pot.
