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 has been limited due to several factors. Stirling engines are known for their quiet operation and potential for high efficiency, especially when using alternative heat sources. However, they also tend to be bulky and heavy compared to traditional internal combustion engines, which poses challenges for vehicle design. Furthermore, achieving the necessary power output and responsiveness for a motorcycle can be difficult.

Thermotorkerékpár prototypes have been developed over the years, often as experimental projects rather than commercial ventures. These machines typically showcase the unique characteristics of Stirling engine power, such as smooth acceleration and low emissions. The heat source for a thermotorkerékpár can vary, with some designs exploring solar power, waste heat, or even wood combustion. The complexity of the engine's regeneration system and its temperature differentials are key to its operation. While still largely a niche technology, the thermotorkerékpár represents an interesting exploration of alternative propulsion systems for two-wheeled vehicles.
