		Rocket stove combustion systems deserve attention for a few reasons:
- they offer close to complete combustion of the wood, meaning they are hyper-efficient and burn super-clean
 - they can reach very high temperatures, and can be hooked up to almost anything we want to use that heat for
 - they can use wood typically considered too small to call firewood
 - they are easily built from common materials.
