Rotary Stirling engines harness waste heat from industrial processes or power generation to produce usable energy. Unlike conventional Stirling engines, the rotary design allows for continuous rotation and smoother energy output. Waste heat is directed into the engine, where it heats a working fluid. The expansion of this heated fluid drives a rotor, generating mechanical power that can be converted to electricity or used for other applications. This process recycles energy that would otherwise be lost, improving overall efficiency and reducing carbon emissions. Rotary Stirling engines are highly versatile and can handle a wide range of heat sources, including industrial waste heat, geothermal energy, and concentrated solar power. Their ability to operate with low emissions and high efficiency makes them an excellent choice for waste heat recovery, contributing to cleaner and more sustainable energy systems globally
