ciency than heat engines. Heat engines, such as internal combustion engines and turbines, convert chemical en-ergy into heat by way of combustion and use that heat to do useful work. The optimum (or “Carnot”) thermody-namic efficiency of a heat engine is known to be: This formula indicates that the higher the temperature of
