The modern Stirling engine is an extra clean low pollution output engine, b ecause the heat is from outside the engine, creation of pollutants is avoided. Also because of the external combustion aspect , a Stirling engine will operate equally well on multiple types of fuel such as natural gas, propane, alcohol, Hydrogen, gasoline, diesel or bio-diesel or heat from the sun. The extra quiet operation of Stirling engines is impressive.
Many engines are by their nature balanced so there is almost no noise from the engine.
A Stirling cycle is truly reversable. It can be used in a heat pump driven by a motor or another Stirling engine. It provides space conditioning using absolutely no CFCs . The Stirling engine is the environmentally friendly way to use heat to produce motion. If you desire to learn more about Stirling engines and this site, join the list.
