Hot Air Stirling Engine Generator Educational Toy

This engine is a balance style, different from the ordinary Stirling model. It was equipped with a multicolor LED installed on the motor. Because of the heat from high-grade alcohol, the engine will run madly and create electricity. The power will go through the wire and drive the multicolor LED lighting. It's a really interesting and imaginative toy.

Featuring a Model: SC02M status of Assembled, the engine operates at a Speed of 1700-2000 RPM (revolutions per minute) and is constructed from materials including stainless steel, brass, bearing steel, aluminum, and quartz glass. The Overall size is 165x95x120mm/6.50x3.74x4.72in (L/W/H), with a flywheel Size of 60x9mm/2.36x0.28in (Diameter/Thickness). The Net Weight is 810g/1.79lb.

The Packing List includes an Engine x1, Lamp x1, LED x1, and Spare tube x1.

Featuring a Model: M16-22-D, this engine has a Speed of 1300 to 1500 RPM and a Weight of 2200g / 4.8 lb. The Size is 210 133 105mm / 8.26 in 5.24 in 4.14in. The Technical parameters include a flywheel diameter of 64mm, driving wheel of 29mm, power cylinder inner diameter of 20mm, and piston path of 20mm.

The Packing List for this model includes an Engine x1, Lamp x2, Wick x1, and LED x5.

This engine is EXTREMELY WELL-MADE. The heating cylinder is made of custom-thick glass material, allowing long-term heating without pressure. It is mainly constructed of metal, allowing it to run quietly and stably (being HEAVY, 1.5LB) at speeds around 1700 RPM. Customers are satisfied with the fit and finish, and all parts have undergone surface treatment to avoid rusting. It is a pleasure to place this engine on a table.

EASY OPERATION & LONG LASTING: Fill the alcohol burner with 95% alcohol (recommended fuel) and light it. Let the light burn the round-ended cylinder for 60-120 seconds, then gently push the wheel, and it will run like a charm.

TWO CYLINDER ENGINE: The dual-cylinder engine is full of power, and the voltage can reach 4-9V. The flywheels will rotate rapidly, causing the generator's LED lights to flicker wildly. When the machine works, it will be very shocking and attracting eyeballs.

EXTREMELY FINE CRAFTED: The base, bracket, and 2 flywheels are made of 6061 aluminum alloy (high strength, weldability, and corrosion resistance). The power cylinder and piston are SUJ2 material with a fine-ground, specially treated surface for high hardness and long-lasting, high-speed operation. The axle joints are connected with very high-precision miniature bearings, providing stability without lubrication. The power and heat cylinders are made of brass and 304 stainless steel, ensuring a long service life.
