Features:

1. Working Principle: The Stirling engine is a heat engine, and its working principle is to cyclically compress and expand air or other gases at different temperatures so that thermal energy is converted into mechanical work.

2. Superior Performance: The model runs quietly and stably when rotating and can rotate for a long time. Low noise, low pollution, low operating costs.

3. Easy Operation: Add 95% alcohol (we recommend this fuel) to the alcohol burner and light it. Let the flame burn on the piston for about 30 seconds, then give the wheel a slight push, and it will work like magic.

4. Excellent Workmanship: The Stirling engine is made of zinc alloy and glass, which is exquisite and beautiful. There are non-slip pads on the bottom of the model, which is safe to use. The overall shape is exquisite, combining texture and beauty.

5. Great Educational Toy: Transparent glass tube and glass alcohol lamp, convenient for direct observation of the piston. It is the best choice as a special gift for students, teachers, children, friends, and colleagues.
