What is the stirling engine?
A Stirling engine is a heat engine that operates 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. The engine is like a steam engine in that all of the engine’s heat flows in and out through the engine wall.

How it works?
This is traditionally known as an external combustion engine in contrast to an internal combustion engine where the heat input is by combustion of a fuel within the body of the working fluid. Unlike the steam engine’s use of water in both its liquid and gaseous phases as the working fluid, the Stirling engine encloses a fixed quantity of permanently gaseous fluid such as air or helium. As in all heat engines, the general cycle consists of compressing cool gas, heating the gas, expanding the hot gas, and finally cooling the gas before repeating the cycle.

IMPORTANT:
1.Please adopt 95% to highgrade alcohol to be the fuel to make sure the air tank can get more temperature, and drive the stirling engine.
2.The temperature of Candle’s light is not workable for this toy, please pay attention.
