Regun Low Temperature Stirling Engine Model, Steam Heat Electricity Generator Machine Education Model Toy, for Kids Craft Ornament, Birthday, New Year Gift

【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.
【Great gift】Good-looking Low Temperature Stirling Engine could be a great gift for your friends or families or yourself. It is almost ready to run: you will only have to install the flywheel. After 30 seconds of installation, put it on a cup of hot water, then it will run like Forrest Gump.
【How it works】Electricity Generator Machine Model is traditionally known as an external combustion engine in contrastto 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'suse of water in both its liquid and gaseous phases as the working fluid,the Stirling e
