Power can be generated in principle by utilizing the naturally occurring decrease with depth of the temperature of ocean water. At one location the ocean surface temperature is 60°F, while at a depth of 1800 ft the temperature is 45°F. Determine the maximum thermal efficiency for any power cycle operating between hot and cold reservoirs at these temperatures.
