The principle of Stirling Motors is both very old and very simple. Invented by Robert Stirling in Scotland in 1816 the motors work on very basic concepts of physics that describe how hot air expands, and has a higher pressure, than cooler air. The air on one side of the displacer piston is heated by an outside source, causing an increase in pressure. The increased pressure pushes the piston to the other side of the chamber, where the air remains cool. Then that chamber heats, and the process repeats. There are usually two pistons, at 90° to each other that can be connected to a crankshaft to move a vehicle or a generator to make electricity. Stirling Motors are very efficient, quiet and, because they are a closed-system with no explosives and no steam, safe.
These beautiful working models are precision engineered and available both in kit form or as ready built items. The quality of the components means assembly is straightforward, resulting in a stunning model which, when fired up, will amaze any observer.
