Stirling machines and atmospheric emissions

The impact that widespread implementation of Stirling machines can have on the reduction of atmospheric emissions is discussed. Stirling engines operate within a closed cycle, which allows thermal input to be independent of the engine itself. When combustion is used as the heat source, it takes place under relatively stable conditions. As a result, the engine and burner tend to generate little noise and low levels of emission. The heat input can come from a number of sources including solar, nuclear, biomass combustion, liquid-fuel combustion, solid-fuel combustion, exothermic chemical reactions, and thermal energy storage. Applications to vehicles, space heating and cooling, and refrigeration and their environmental impact are discussed.<
