    Stirling Engine

    A Stirling engine is a heat engine that operates by cyclic compression and expansion of air or other gas using a temperature differential, resulting in a conversion of heat energy to mechanical work. They can run directly on any available heat source, such as solar, geothermal, biological, nuclear sources or waste heat from industrial processes. The engine can be used for heating and cooling, underwater power systems, solar power generation, heat pumps, marine engines, low power aviation engines, and low temperature difference engines.

    Reducing Mechanical Losses

    Reducing Mechanical Losses

    Stirling engines require large temperature differentials for efficient operation. Those that run on small temperature differentials are quite large for the amount of power that they produce. Our goal is to reduce mechanical losses in a Stirling engine, in order to have a small temperature differential and keep the engine size relatively small. To do this a thorough thermodynamic and mechanical analysis must be performed, along with a precision machining of parts.
