Hot Air Stirling Engine 2 Cylinder Colorful LED Education Toy Electricity Power Generator Model (M14-22-S) - A Fascinating Mechanical and Educational Experience

Explore the intriguing world of Stirling engines with the M14-22-S model, a captivating educational toy that demonstrates the principles of external combustion engines through its innovative design and colorful LED lighting.

How It Works:

  • The M14-22-S Stirling Engine operates as an external combustion engine, using an external heat source to cycle a fixed quantity of gas through compression, heating, expansion, and cooling phases. This differs from internal combustion engines and steam engines in its unique method of operation.
  • To achieve optimal performance, it is recommended to use high-grade alcohol (at least 95% concentration) as fuel, ensuring efficient and powerful operation.


  1. Electricity Generation: This model generates power between 4-9v, complemented by vibrant LED lights. The rapidly spinning flywheel creates a mesmerizing display of flickering LEDs, making it an eye-catching addition to any setting.
  2. Exquisite Craftsmanship: The model boasts two cylinders made from quartz tube material, with a base, bracket, and dual flywheels constructed from bamboo. The power cylinder and piston, made from SUJ2 material, are finely ground for high durability and extended life span, surpassing 20 years.
  3. Secure Packaging: Each glass tube is individually packed in bubble bags to prevent damage during shipping. The alcohol lamp is carefully wrapped for safe handling.
  4. Perfect Educational Gift: Ideal for kids' science projects, physics and mechanics learning, this model is a brilliant tool for enlightening learners about scientific concepts. Its design and craftsmanship make it suitable for enthusiasts of all ages and backgrounds, offering a delightful and educational gift option.
