Fetching lower temperature cooling water to condense steam isn't worth the
effort. In fact, it would be a negative. The ideal input temperature for a
steam generator is the highest at which the water is still a liquid.

The fresh water is the most plausible feature. The thermo cycle cannot
have an efficiency much over 5%.

Why not use the cold water for cooling conventional power plants?

Diamond Shoals is only 8 miles from the shelf. It might make sense on
the E. Coast in that one location.

Pipes draw warm water from the ocean

surface and cold water from the seabed.

The warm water enters a vacuum chamber

and is evaporated into steam that drives an

electricity-producing turbine. The cold water

condenses the steam back into water for

drinking and irrigation.

Here, calculate the power required to pump the water:
