InStove rocket stove gas flow diagram... At the heart of these stoves is an advanced, insulated metal combustion chamber built from high-temperature 310 stainless steel and 601 nickel alloys. The “rocket stove” design concentrates heat and mixes combustion gasses to create operating temperatures in excess of 1100 degrees Celsius, which allows the stoves to literally “burn up the smoke.”

A Stirling engine is a heat engine operating by cyclic compression and expansion of air or other gas, the working fluid, at different temperature levels such that there is a net conversion of heat energy to mechanical work.[1][2] Or more specifically, a closed-cycle regenerative heat engine with a permanently gaseous working fluid, where closed-cycle is defined as a thermodynamic system in which the working fluid is permanently contained within the system...
