Vertical Flywheel Stirling Engine

This engine is driven by the temperature differential between the top and bottom plates. To create enough temperature differential, simply put it on a cup of hot water. The rotation speed depends on the temperature differential: the higher, the faster.

When in good condition, that is, after working for a while and being lubricated, it can reach a speed around 220-250 RPM driven by boiling water. 

Features:

• DIY Low Temperature Flywheel Stirling Engine Model Motor Power Generator Physical Kits
• Theory - Similar to internal combustion engine: the burning alcohol lamp provides heat power to make the expansion of gas inside, then the gas molecular internal power increasing and working strongly to the flywheel. With the help of the flywheels, heat energy will convert into mechanical work, then into electric energy
• With the help of the flywheels, heat energy will convert into mechanical work
• Great educational toy, classroom or laboratory experimental teaching aids, cultivate children's interest in physics, more intuitive and easy to understand
• Great gift for your friends or families; also a super addition for home decor
• A Stirling engine is a heat engine that operated by cyclic compression and expansion of air or other gas (the working fluid) at different temperatures, such that there will be a net conversion of heat energy to mechanical work
