Sunnytech Stirling Mini Hot Live Steam Engine for Low Temperature

The Stirling Engine Model LT001 is a remarkable piece of engineering featuring a silver plate and gold flywheel. Capable of reaching speeds up to 180-200 RPM, this Stirling engine boasts a starting temperature difference of approximately 20°C (68°F). Crafted from high-quality materials, including carbon steel, nickel-plated carbon steel, stainless steel, glass, bronze, PVC foam, and plastics, the LT001 model measures 101014cm (3.943.945.51 in) and weighs 250g (0.55 lb). The package includes a stirling engine and a detailed user manual.

The BJ001 model, on the other hand, is a steam boiler-powered device that operates at speeds ranging from 1300 to 1500 RPM. Measuring 6055120mm (2.362.164.72 in) and weighing 260g (9.17 oz), this compact engine is made of brass and stainless steel. The BJ001 package includes a steam boiler, an alcohol burner, and three brackets.

The Stirling engine can be easily operated by simply placing it on a cup of hot coffee. As the coffee cools, the engine slows down, indicating the optimal drinking temperature. This physical powertrain mechanism can also be used on top of ice cubes, where the temperature difference creates an even faster and more exciting display. Some users have even placed the engine on a USB hot plate, allowing it to run continuously for weeks on their desks.

It is important to note that the Stirling engine should not be placed directly on a stove or in a fire, as the plastic parts may be damaged. The engine is designed to be a high-end handicraft, appreciated for its unique styling and dignified retro design.

To operate the BJ001 steam boiler-powered engine, users must open the brass boiler, fill it with water to two-thirds capacity, and then fill the alcohol burner with 95% alcohol before igniting it. After about 2 minutes of heating, steam will start to emerge from the air outlet, and the flywheel can be pulled to set the engine in motion.

During the initial operation of the BJ001 engine, some water may be pushed out by the steam through the steam holes in the middle stand base, and some water may also spray out with the steam from the gas outlet at the top of the middle stand base. Users can use tissue paper to absorb this water.

Both the LT001 Stirling engine and the BJ001 steam boiler-powered engine offer unique and captivating experiences for those interested in the world of physical powertrain mechanisms and engineering.
