Hot Air Stirling Engine 2 Cylinder Colorful LED Education Toy Electricity Power Generator Model (M14-22-D)

This Stirling is an interesting model toys, this Stirling engine mode uses the heat by alcohol lamp to generate electric. The electric will light the led light to emit different colors. It is a great opportunity for you to investigate how Stirling engine works. It can inspire your curiosity and creativity.

How it works?
This Stirling Engine 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.
We suggest you adopt at least 95% high grade alcohol to be the fuel. Because 95% high grade alcohol can produce enough hot power to drive the engine. By the heat from high grade alcohol, the engine will run madly and create the electricity.

1, Stirling Engine Generate Electricity ---- The Stirling engine model power generation voltage is 4-9v and match colorful LED light. The flywheel rotating faster, which will make the generator's LED lights flickering wildly. When the machine works, it will be very shocking and attracting eyeballs.
2, Superb Craftsmanship ---- The two cylinder is made of quartz tube material, The base, bracket and 2 flywheels are made of 6061 aluminum alloy(High strength, weld-ability and corrosion resistance); Power cylinder and the power piston is SUJ2 material fine grinding surface of special treatment, high hardness. Heating cylinder of quartz glass- the heat resistance is better than ordinary glass. Durable, the life working time is more than 20 years.
3, Strict Packing ---- glass tube is packaged separately with bubble bag to avoid damage during shipment. easy to take off the package, and put it back to the place. The packing bag of alcohol lamp cotton wear into the metal cap lamp.
4, Great Gift for Everyone ---- It's a vivid model displaying basic principle of external combustion engines. People bought it for kids' science project, physics/mechanics learning, etc., enlightening them to explore more scientific knowledge. This engine is also a well-designed and crafted mechanical toy suitable for people of all ages from all works of life. It will definitely be a fantastic gift for those you love and SELDOM will our machine fail to cheer them up!
