Aibecy Mini Hot Air Stirling Engine Motor Model Heat Power Electricity Generator Mchine with LED Light

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.
It is also an electricity generator, the power can light up mini LED light.
The teaching and learning process will be more intuitive and more interesting.
Well assembled, you just need to install the LED light and prepare the alcohol.
The biggest advantage of external combustion engine is that its' output and efficiency won't be affected by altitude, even at high altitude it works well.
Made of exquisite aluminum alloy and glass.
