Optimized Title: Stirling Engine Education Model Kit (DWCL-01) for Low Temperature Heat

This Stirling engine, model DWCL-01, features a Gray color and a size of diameter * height (Φ89135mm) / 3553in. Weighing 150g/0.33lb, it is constructed with Carbon Steel, Nickel Plated Carbon Steel, Stainless Steel, Glass, Bronze, PVC Foam, and Plastic. It can operate at speeds up to 180-200 RPM, with a startup temperature difference of approximately 20°C/68°F.

The package includes 1* Stirling engine and has passed Child Safety, Toxic Element Testing, Flammability Testing, and Physical and Mechanical Testing of ASTM-963 Toy Safety Standard. It complies with applicable regulations and standards under CPSIA and any other actions enforced by CPSC.

This Stirling engine is an excellent teaching tool for educators. Often, science toys or demonstration devices are inexpensive to manufacture and may not always function as intended. However, this Sterling engine operates remarkably well. It is easy to assemble, with well-made parts, and it is straightforward to get it running. By heating the base with a cup of hot coffee or hot water, and gently pushing the engine after about a minute, it will continue to run for several minutes. The hotter the water, the faster the engine will operate.

The Stirling engine features a mirror-finish stainless steel base, glass cylinder liners, a zinc alloy flywheel, and surface-treated parts to prevent rusting, ensuring a well-made and durable design. The simplicity of operation is remarkable - just pour a hot drink, place the Stirling on the mug, and it will work magically. As the engine slows down, the hot beverage temperature will be suitable for drinking. It also works on ice, as placing the Stirling over a glass of hot water and adding small ice cubes to the upper plate will increase the temperature difference, causing the engine to run faster and more energetically.

This Stirling engine is connected to a stable power source and can run continuously for more than 24 hours without damage. The Stirling base has plastic parts and should not be approached by fire.

The exquisite and beautiful Stirling engine has a wide range of applications, including physics/mechanical learning, teacher demonstration props in the classroom, gifts for friends, family, and children's science projects, as well as children's birthday gifts. By placing the Stirling engine on a cup filled with hot water and gently pushing the flywheel to make it run, it can serve as a wonderful toy that enhances communication, as many guests may not understand how it works and will be eager to learn more, thereby breaking the ice successfully.
