Both technology lovers and steampunk design fans will enjoy this small power plant and its lively rattling engine. The engine is powered by the heat of a spirit flame.
In principle, a Stirling engine works by means of two pistons which are located in cylinders of different temperatures and connected to the flywheel. Air can flow back and forth between the cylinders. In the colder cylinder, the air contracts and sucks the piston inwards. As a result, the piston pushes the cold air over into the warm cylinder where it heats up, expands, and pushes the warm piston outwards. Together they move the flywheel which will now turn over its vertex and reverse the kinetic energy. With its momentum, the flywheel pushes the warm piston back into the warm cylinder and pulls the cold piston out of the cold cylinder. As a result, the air flows back from the warm cylinder into the cold one. It contracts - and the cycle begins again.
