Question

It has been suggested that a heat engine could be developed
that made use of the temperature difference between water
at the surface of the ocean and water several hundred
meters deep. In the tropics, the temperatures may be 27°C
and 4°C, respectively. (a) What is the maximum efficiency
such an engine could have? (b) Why might such an engine
be feasible in spite of the low efficiency? (c) Can you imagine
any adverse environmental effects that might occur?
