Stirling Engine Kit: Low-Temperature Educational Toy Model

This low-temperature Stirling engine is designed with an optimized and compact structure. Its convenient portability allows you to bring it to various settings like home, schools, or offices.

  1. Exceptional Construction: The engine is built with premium materials, guaranteeing durability and elegance. Its base features a polished stainless steel surface, a glass cylinder liner, precision bearings, steel shafts, and a zinc alloy flywheel. Surface treatments ensure rust prevention, and it operates oil-free.
  2. Effortless Operation: Place the Stirling engine on a cup filled with hot liquid. After preheating for 30-60 seconds, gently push the flywheel clockwise to initiate rotation. The engine will operate automatically, and its speed can be adjusted by varying the liquid temperature. When the liquid cools down, its optimal temperature for consumption will be reached.
  3. Extended Endurance: Under continuous power supply, the engine can operate for over 24 hours without any interruptions. One user successfully operated the Stirling engine on a USB hot plate (not included) for several weeks while it remained functional.
  4. Versatile Gift: With its affordable price and elegant presentation, the Stirling engine is an ideal gift for science projects, physics and mechanics demonstrations, teacher’s aids, birthdays, etc.
  5. Engaging Conversation Starter: The Stirling engine sparks curiosity and amazement among observers. When gently fueled by hot liquid, its intricate mechanism comes to life, creating a captivating display that leaves guests in awe, generating delightful conversations.

Important Safety Precautions:

  • Allow the engine to cool naturally after operation.
  • Avoid touching high-temperature parts to prevent burns.
  • Do not expose the engine to temperatures exceeding 150 degrees.
  • Never use flame-based heat sources.
  • Suitable for individuals aged 8+ and should be operated under adult supervision.

    1. Place the engines on a 5/6 cup/mug of boiled water for 30 seconds, spin the flywheel (this is to test if they work well)
    2. If they do, place the engine into freezer/refrigerator for a few minutes until the temperature of the engine drops to about 30°F below room temperature. For example, when room temperature is 77°F (25℃), then the desired/ideal temperature of the engine should be 45-50°F (5-10℃)
    3. Then place the bottom plate of the engine in your palm (hands should be warm) for one minute or even longer to ensure more surface area is in contact to heat the plate evenly, see video for reference.
    4. Spin the flywheel with your other hand to start the engine.
