Aibecy Mini Hot Air Stirling Engine Motor Model Electricity Generator Wooden Base Physics Science Educational Toy

Features: A Stirling engine is a heat engine that operates by cyclic compression and expansion of air or other gas (the working fluid) at different temperatures, such that there is a net conversion of heat energy to mechanical work. The electric engine generate enough power and light up the mini lamp after it reach a certain speed. Inspires students' curiosity, make teaching more intuitive and interesting. With high-quality wooden base, a fashion decor for home/ office. A great gift for all ages.
