Chapter 15, Problem 10Q

To determine

Why the internal energy of the oceans cannot be put into useful work?

Answer to Problem 10Q

Solution:

Due to heavy capital cost, engineering obstacle and geographical difficulties the internal energy of the oceans cannot be put into useful work.

Explanation of Solution

To use the internal thermal energy of the oceans, a heat engine must be developed that can work between two different temperatures. If the temperature difference between the surface water and deep water must be used, then some engineering obstacle, geographical difficulties and high expense must be overcome. So,difficulties the internal energy of the oceans cannot be put into useful work.
