Sunnytech's popular products include the Solar Flag Light, which can light up a flag with dazzling glory, and the Alancing Toy Kinetic Art Low Temperature Stirling LT001, which is a great gift for kids' science projects, teachers' demonstration props, and birthday gifts for friends, families, parents, and kids.

The Stirling engine motor, which can be used for kids' science projects, physical/mechanical learning, and teachers' demonstration props, is an extremely fine-crafted product. The base, bracket, and flywheels are made of high-strength, weldable, and corrosion-resistant 6061 aluminum alloy, while the power cylinder and piston are made of SUJ2 material with a fine-grinding surface and high hardness. The axle joints are connected with high-precision miniature bearings, ensuring stability without lubrication, and the power and heat cylinders are made of brass and 304 stainless steel for long service life.

The Stirling engine is easy to operate and long-lasting. Users need to fill the alcohol burner with 95% alcohol, let the light burn the round-ended cylinder for about 20 seconds, and then give the wheel a gentle push, and it will run like a charm. The engine can run for over 8 hours continuously without any issues, as tested by one customer.

The Stirling engine is much larger and heavier than most similar products, weighing 4.8 lbs, which allows it to run stably on a table. It is an amazing and fantastic product at its price point, with an elegant gift package that makes it a suitable gift for a wide range of applications, including kids' science projects, physical/mechanical learning, and teachers' demonstration props, as well as birthday gifts for friends, families, parents, and kids.
