Kartonbausatz Stirling-Motor.

The Stirling engine runs on a cup of coffee Or on an ice pack. The revolutionary concept of this hot air engine was invented in 1816 by the Scottish pastor Robert Stirling and has gained special relevance today. The principle is as ingenious as it is simple: in a sealed, heated cylinder on its underside, a piston pushes the trapped air back and forth between the hot and cold sides The air expands and contracts again every time, and this is converted into a rotating motion via a working piston and a crankshaft. As an energy source, any heat or cold source with which a temperature difference can be generated, from open fire to solar energy to otherwise unused heat or cold. Place this fully functional Stirling engine on a cup with boiling. K, Manufacturer: AstroMedia GmbH
