LTD Stirling Engine: This model is a fantastic intelligent machine made of aluminum alloy and brass metal CNC, featuring bearing rolling friction pairs for all moving parts in a γ-type air displacement piston type and gear transmission structure design. The side of the base is processed with a mirror design, making it both exquisite and beautiful.

Simple Operation and Easy-to-use: Simply place the engine on a water cup or coffee cup with a temperature of 90 degrees Celsius or more. After half a minute of preheating, the swing flywheel will operate magically, making it an enjoyable desk toy.

Durable and Continuous Operation: After extensive testing, the engine can run for at least 100 minutes continuously. It operates silently and is not easy to damage. As long as the temperature difference is maintained, it will run for a long time without stopping, making it a perfect long-term addition to your desk.
