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

But seriously it’s an interesting idea. Lots of space for ecological catastrophe but depending on how the heat exchanger is designed it could be really cool. There’s so much water in the goddamn ocean I believe you could potentially do serious cooling at a very slow rate over a very large area.

how so?

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.
