GENYUU Mini Hot Air Stirling Engine Model - External Combustion Physics Science Experiment Kit for Adults & Teens - Educational STEM Toy for Home, Office & Classroom Demonstrations

Metal

Fine Workmanship: The main parts are made of aluminum alloy and brass, with a wooden base, highlighting the high-end atmosphere; the heating cylinder is made of thick quartz glass, which is sturdy and durable, resistant to high temperatures, and is not easy to wear after long-term operation

Low Noise: When the Sterling engine is running, since the combustion of fuel is continuous, it avoids the detonation work and intermittent combustion process similar to the internal combustion engine, thereby achieving the advantage of low noise.

Lasting Performance and Safe Package: It can run many hours continuous without any broken which can be tested by one customer. And We have carried out a comprehensive packaging for the product, which can prevent the product from being damaged during transportation.

Working Principle: Stirling engine is an external combustion engine. It only needs to be heated by an alcohol lamp and the flywheel can be operated stably. The side knob can adjust the amount of air flow to control the speed of the Stirling engine, which is convenient for observing the dynamics of the piston

Best Gifts: This amazing product can be suitable as a holiday gift for technology fans, family, friends and teenagers for studying the working principle of external combustion engines, inspiring curiosity and creativity. And it also can become a cool desktop decoration.
