air engine

The TV presenter Jem Stansfield modified this small moped to function on compressed air stored in two high pressure carbon fiber tanks, like the ones that the firefighters use. The engine has been replaced by two rotary air engines.

The Can Stirling engine can rotate using a candle as the heat source. This engine is constructed with very simple materials. There are a can, a balloon, a wood board and others.

In 1820, when steam engines operated everywhere, Robert Stirling, a Scottish vicar, and his brother James built a new engine. They used an outside burn, additionally hot air was sufficient for the operation of the engine.

he Di Pietro motor concept is based on a rotary piston. Different from existing rotary engines, the Di Pietro motor uses a simple cylindrical rotary piston (shaft driver) which rolls, without any friction, inside the cylindrical stator.
