A rocket stove is a portable stove that cooks food quickly and efficiently. Unlike an open fire that burns great quantities of fuel, the rocket stove burns very little. You can cook a whole meal on it just by burning a few sticks. Rocket stoves can be made very easily with a few simple materials, and are a great resource when the power fails.

Things you need
- Large metal can (with lid)
- 1134gr. can (with 4-inch opening)
- Metal duct elbow (4-inch opening)
- Tin snips
- Insulating material
Cut a hole 4 inches in diameter in the side of the large can, with the bottom of the hole 2 inches from the bottom edge of the can. Using the 1134gr. can as a template, draw the hole with a permanent marker, then carefully cut out with tin snips.
Insert the duct elbow through the hole from the inside so that approximately 2 inches of one end is sticking through the front. The other end of the elbow should point upwards towards the top of the can and be relatively centred inside. Place a stone or piece of brick underneath the elbow to support it from the bottom of the can for stability.
Fill the body of the large can on the outside of the duct elbow with insulating material, such as vermiculite, perlite or sand, until it's within 1 inch of the top of the duct elbow.
Cut another hole 4 inches in diameter in the middle of the large can lid and place over the top of the duct elbow, until the lid rests on the insulating material.
Cut the bottom out of the 1134gr. can. Slide this can over the horizontal end of the duct elbow until snug.
Gather your fuel source. The rocket stove burns very efficiently on twigs and small pieces of scrap wood. Light a few twigs and feed the wood through the front can until the fire is burning at the curve of the duct elbow. Continue to feed slowly to keep the fire at a steady level. Set a grill over the top of the rocket stove and place the cooking pot on top of it.
Tips and warnings
- To cook a whole meal at once, make two rocket stoves.
- Be careful to not touch the hot surfaces of the stove while cooking.
- Food will cook quickly on the rocket stove. Stir foods frequently that are prone to burning.
- Check food frequently to ensure it is not burning.
