41. By early Monday, the tall thunderstorms surrounding its center, the heat engine of a hurricane, collapsed. 42. Statements 2 and 3 apply to heat engines . 43. A common misconception is that the exergy efficiency compares a given cycle to a Carnot heat engine . 44. In 1977 Prof . Loeb invented a method of producing power by a reverse electrodialysis heat engine . 45. The heat energy released by reactions of fuels is converted into mechanical energy via a heat engine . 46. Such analysis is based on the definition of the Carnot heat engine efficiency and the psychrometric concepts. 47. A widely accepted theory is that mantle plumes are an essential part of the global heat engine . 48. Power cycles can also be divided according to the type of heat engine they seek to model. 49. So the energy lost to the environment by heat engines is a major waste of energy resources. 50. The sputtering heat engine was a sign that the storm, while still dangerous, was beginning to weaken.
