Thermotorkerékpár
A thermotorkerékpár, also known as a Stirling engine motorcycle, is a type of unconventional vehicle that utilizes a Stirling engine for propulsion. A Stirling engine is a closed-cycle regenerative heat engine that operates by the cyclic compression and expansion of a working fluid, typically air or helium, at different temperatures. This process converts thermal energy into mechanical work, which then drives the motorcycle's wheels.
The concept of using Stirling engines for transportation is not new, but its practical application in motorcycles
Thermotorkerékpár prototypes have been developed over the years, often as experimental projects rather than commercial ventures.
