Build a Rocket Stove

The video’s clever design for a dual-burner DIY rocket stove uses only six concrete masonry units (CMU), also known as cement blocks or foundation blocks. By stacking the blocks as demonstrated, you’ll be able to channel enough heat from a small fire to cook food in two separate pots.

rocketstoveTo build the rocket stove featured in this video, you’ll need 3 standard cement blocks, 2 half-blocks and one stretcher unit. As the video demonstrates, the blocks can be arranged quickly, and your rocket stove will be fully operational in a matter of minutes. Start by placing one standard block lengthwise, with its solid surface down, and topping it with the stretcher unit having its openings facing skyward. Flank this arrangement on each end with one standard block, openings turned out to the sides (the side-facing openings will function as fuel magazines into which you’ll feed the flames). Place the half-blocks on top to create two vertical chimneys, over which you can place recycled burner grates to support cooking pots and to allow for a draught. And that’s it: Now you know how to build a rocket stove for cooking.

The video also includes instructions to build a more compact, single-burner rocket stove using just four cement blocks.
