Attention: 1.If there is a little noisy, ONLY use a little graphite dry lube quieted it down nicely. 2.Prohibit to add oil to lubricate.Because the oil will mix with dust in the air, and become a oil-dirt, finally make the friction to be even bigger.The stirling engine can't run freely.
How it works: This is traditionally known as an external combustion engine in contrast to an internal combustion engine where the heat input is by combustion of a fuel within the body of the working fluid. Unlike the steam engine's use of water in both its liquid and gaseous phases as the working fluid,the Stirling engine encloses a fixed quantity of permanently gaseous fluid such as air or helium. As in all heat engines, the general cycle consists of compressing cool gas, heating the gas, expanding the hot gas, and finally cooling the gas before repeating the cycle. You can put the stirling motor toy in top of hot water to make the temperature difference. You also can put it in top of ICE to get the termperature difference, Just enjoy the toy!

This little engine is very well made, and is fascinating to watch. It heats up quickly, and a slight nudge on the flywheel sets it going at a high speed. I use mine as a teaching tool. If you place small neodymium magnets (alternating north and south upward) evenly on the flywheel and hold a coil of battery wire close to it, it will generate AC current, and in doing so, you will demonstrate all the energy transformations that happen in the typical fossil fuel electrical plant.
Even cooler, as you bring the coil closer to the flywheel, it will slow down, demonstrating that energy cannot be created, only transformed; the kinetic energy of the flywheel is being transformed to electrical energy, and therefore, the wheel must slow down as the kinetic energy is lost.
My only criticism is that the fuel container needs a better and longer-lasting wick ( This is cheap and easy to do). That isn't enough to make me want to give it less than five stars, however.
Okay. This is really an unusual thing and one would think it just a conversation piece. But -- it makes a perfect tea-brewing timer! Tea in the cup, cover with boiling water, put engine on top, and give it a spin to start. It will slow down initially, then get faster and faster and when it starts to slow down (and I can hear it), tea is brewed! And since it's been covered, it's still hot.
I ordered this product for my son's birthday. So far, he's not only enjoyed it for himself, but also explaining the Physics behind its function to anybody willing to listen! It has a whimsical feel and it is rather cathartic to just listen and watch it whir. It also gives us an excuse to share a cup of coffee....one cup goes to running the engine!
