【Great Gift】This great looking low temperature Stirling engine would be a great gift for your friends and family, or even yourself. It's almost ready to run. Just install the flywheel. 30 seconds after installation, place it in a cup of hot water, and it will run like Forest Gump.
What is a Stirling engine? A Stirling engine is a heat engine that operates by cyclic compression and expansion of air or other gas, the working fluid, at various temperature levels so that there is a net conversion of thermal energy to mechanical work. All of the heat in the engine enters and leaves through the walls of the engine. It is prohibited to add oil for lubrication, because the oil will mix with the dust in the air and make the oil oily, which can eventually increase friction and prevent free running.
Material: Alloy + Steel + Glass Size: 10 x 10 x 12cm Weight: 250g Rotation speed: 180 - 200 RPM. ☂ An engine of the future, born about 200 years ago? Learn the mechanism of energy that is friendly to people and the environment. Clean engine system. Place the Stirling engine on top of a cup of hot coffee or tea, and after about 30 seconds, gently move the rotating ring with your finger. *The rotation speed varies depending on the temperature. *Be careful not to get burned.
Principle: Stirling engines are traditionally known as external combustion engines, as opposed to internal combustion engines, where heat input comes from the combustion of a fuel within a body of working fluid. Unlike steam engines, which use water as the working fluid in both liquid and gas phases, Stirling engines enclose a fixed amount of a permanent gaseous fluid, such as air or helium. As with all heat engines, the general cycle consists of compressing a cold gas, heating the gas, expanding the hot gas, and finally cooling the gas before repeating the cycle.
[Applicable range of Stirling engines] Stirling engines are suitable for teaching students the principles of engines, as educational toys, teaching equipment, students like students, live science, and training like the brain. It starts smoothly with a mug of hot water. Then, place it on cold ice and it will rotate in reverse! It is a Stirling engine that spins with a lovely clatter. It is a physics experiment toy that is soothing just to look at. ☂ It is durable and has almost no friction, making it an extremely convenient introductory thermodynamics teaching material for students who like science. It is also recommended as a gift.
