Sunnytech Low Temperature Stirling Mini Hot Air Kits for Education

The stirling engine model LT001 features a silver plate and gold flywheel, capable of reaching speeds up to 180-200 RPM. It has a starting temperature difference of approximately 20°C (68°F). Constructed with materials such as carbon steel, nickel-plated carbon steel, stainless steel, glass, bronze, PVC foam, and plastics, the engine measures 101014cm (3.943.945.51 in) and weighs 250g (0.55lb). Each package includes the stirling engine and a detailed user manual. Spare parts are available upon request.

The single flywheel hot air stirling engine, model HA001, operates at a speed of 1300 to 1500 RPM. Measuring 100x45x50mm (3.931.351.5in) and weighing 200g (5.6 ounces), it is constructed with steel, copper, and aluminum. We recommend using at least 95% high-grade alcohol as the fuel, as it can generate sufficient heat to drive the engine effectively. The heat from the high-grade alcohol causes the engine to run vigorously, generating electricity.

This stirling engine is an expertly crafted and well-made device that runs smoothly. It features a mirror-surface stainless steel base, a glass cylinder liner, and a zinc alloy flywheel. All components have been treated to prevent rusting, and the engine operates without the need for oil.

The engine is easy to operate - simply place it on a cup of hot coffee, and it will run magically. As the coffee cools, the engine's speed decreases, indicating that the coffee is now at a suitable drinking temperature. The stirling engine can also be placed on top of ice cubes, and some users have even put it on a cup of hot water with small ice cubes on the upper plate, creating a larger temperature difference and causing the engine to run faster and more enthusiastically.

With proper care, the stirling engine can run continuously for over 24 hours without any issues, provided there is a continuous power supply. One customer placed the engine on a USB hot plate (not included in the package) and it ran on his desk for weeks. However, it is important to avoid burning the engine's base or placing it in a stove, as the plastic parts may become damaged.

This stirling engine is designed with a reasonable and compact size, incorporating a lever mechanism and a crank-rocker mechanism, giving it a visually appealing and mechanical appearance. It features various mechanical components, including a connecting rod, piston, crankshaft, lever, belt drive, gearing, worm drive, transmission, threaded fasteners, rolling bearings, plain bearings, heat transfer, and sealing techniques, all within a compact 100x45x50mm frame, making it convenient to bring home, to school, or to the office.

The stirling engine is a captivating conversation piece for your desk. Watching people's reactions as they observe the flywheel spinning is a delightful experience. By adding some combustibles and getting the flywheel going, you can entertain your guests and break the ice with this marvelous toy.
