Unlike the steam engine's use of water in both its liquid and gaseous phases as the working fluid, the Stirling engine encloses a fixed quantity of permanently gaseous fluid such as air or helium. As in all heat engines, the general cycle consists of compressing cool gas, heating the gas, expanding the hot gas, and finally cooling the gas before repeating the cycle. <br><br> <b>100% SATISFACTION GUARANTEE</b><br> We're so confident that you'll agree our model is the best that we're offering a 30-Day DARE TO COMPARE Money Back Challenge!
