A typical temperature for surface water in a tropical ocean is 27°C. Whereas at a depth of a kilometer or more it is only about 27°C whereas at a depth of a kilometer or more it is only about 5°C. It has been proposed to operate heat engines using surface water as the hot reservoir and deep water as the cold reservoir. What would the maximum efficiency of such an engine be? Why might such engine eventually be practical proposition even with so low an efficiency?
