They’re losing efficiency by placing this in an ocean instead of a freshwater source.

how so?

[-] mrfugu@hexbear.net 8 points 5 days ago

because the heat capacity of fresh water is bigger than salt water (more energy is required to increase temperature)

tho to be clear I mostly said that as a joke.

if you can find a lake with distilled water or liquid helium tho

what's neptune's moon game like?

Depends on how it was made they could use n pentane, or some other low boiling point fluid as thermal fluid, and a heat exchangers between that and the sea at different depths.

Water absorbs a lot of energy in the conversion from liquid to gas. Saltwater leaves behind salts when evaporated that immediately ruin the efficiency of your thermal exchange system, so it has to remain in liquid form

Doubt theyd need any part of the ocean to reach boiling. Avoids lots of problems to just have a larger heat exchanger that operates at lower temps.
