A rocket stove is a super-efficient small combustion stove. Its intelligent design makes use of any small fuel sources such as twigs, small branches, pine cones, and dry grass. These small fuel sources are burned in a combustion chamber containing a verticle chimney. The design ensures nearly complete combustion. This means you’re getting more heat output (for warmth or cooking) than traditional firepits or even wood stoves. Rocket stoves are no rocket science, but there is still a science to how they work. Luckily, they do not require elaborate mechanics, and they surely aren’t dependent on either gas or electricity to cook you a delicious meal and satiate your hunger.
