There has long been an interest in using the vast quantities of thermal energy in the oceans to run heat engines. A heat engine needs a temperature difference, a hot side and a cold side. Conveniently, the ocean surface waters are warmer than the deep ocean waters. Suppose you build a floating power plant in the tropics where the surface water temperature is āā 30 āCāC. This would be the hot reservoir of the engine. For the cold reservoir, water would be pumped up from the ocean bottom where it is always āā 5 āCāC. What is the maximum possible efficiency of such a power plant? In%.
