- The body is made of one-piece aluminum alloy material, which is sturdy and durable. It has an aluminum alloy base to reduce air leakage. Higher precision, smooth and durable. The texture and appearance are superior.
- Single connecting rod suspension type free piston can make you more clearly observe the operation of the engine and understand its principle.
- Not only can be used as teaching AIDS, decorations, but you can also do it by yourself.
- How to use: The base of the machine is made of aluminum alloy. The base is 10cm in diameter. The cup (the diameter of the cup is less than or equal to 10cm so that Sterling does not fall) is filled with hot water (the water temperature can’t be lower than 65 degrees, the machine base will run at least 50 degrees). The hot water level is close to the mouth of the cup, which will make the Stirling base heat faster. Preheating for about 1 minute, and turn the flywheel by hand, after that the machine can run by itself.
Do not add gasoline or fire to all parts! It can not be soaked in hot water! Be careful not to touch the hot water.
