A research group plans to construct an engine that extracts energy from the ocean, using the fact that the water temperature near the surface is greater than the temperature in deep water. If the surface water temperature is 26.0°C and the deep-water temperature is 14.0°C, what is the maximum efficiency such an engine could have?
