Part A 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. What is the maximum possible efficiency of such a power plant? Suppose you build a floating power plant in the tropics where the Express your answer with the appropriate units. surface water temperature is # 35 "C. 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 ~ 6 .C. DA AEd ? o Submit Request
