A rocket cook stove is a super-efficient stove that can use just about anything for fuel — including small twigs, scraps of wood or even dried dung if you’re really in a pinch.
The principle behind the operation of the rocket stove is quite simple: a direct-to-cooking-surface insulated combustion chamber ensures nearly complete combustion of the fuel, giving off more heat, and burning the material quickly and intensely.
Although often used as portable cook stoves, rocket stoves are great alternatives to barbecues and fire pits, using much less fuel. This means you collect less wood. It also means you save money by not having to purchase propane.
Let’s get right into how you can make your own rocket cook stove with minimal time and money. In fact, you probably have most of what you need to build the stove laying around the house, and if not, you can cheaply buy the materials. Assuming you already have a drill and most of the essential parts (like a wheel barrow), you likely can build this for under $10.
