How to Make A 16-Brick Rocket Stove
Here, “Dr. Larry Winiarski makes a clean burning rocket stove using 16 adobe bricks at the Rotary International-sponsored Integrated Cooking Workshop in Tlautla, Mexico.”
Important points: The advantages of this kind of stove – rocket stoves are easy to construct, burn wood extremely efficiently, so a little wood goes a long way, generate very little smoke, and burn hot.
The stove he demonstrates is made with unfired adobe brick that was made with plant material (straw) as a binder. This makes for light but very well insulating bricks.
solarwindmama who posted this video to YouTube says that she made a similar stove with fired red brick from Home Depot and it worked but that she thinks that the heat would have been more concentrated with unfired adobe brick.
Point 2: Rocket stoves have to be used outside or carefully and properly vented, otherwise you risk carbon monoxide poisoning.
