https://www.eia.gov/energyexplained/hydropower/images/oceanthermal.pngYou probably need to study the physics of evaporation. Even at room temperature water vapor evaporates from liquid water. What is important is that this vapor has a pressure. The condenser has a lower vapor pressure.
The difference in temperature is what drives the difference in vapor pressure. The pressure difference provides the energy to drive the turbine.
We are used to high temperatures and pressures being used for power generation. That is not required. It does make the energy transfers more efficient.

The difference in temperature is what drives the difference in vapor pressure. The pressure difference provides the energy to drive the turbine.

I just wonder why we are discuss various fluids, when the whole concepts of such power plants are flawed.
Due to the very small temperature difference (20 C) the Carnot efficiency is quite lousy, from 27 C to 7 C only 6.6 %.
https://en.wikipedia.org/wiki/Carnot_cycle
If you move the cold end below the thermocline (several thousand meters) you will find +2 C water and gave a 'huge' temperature difference of 25 C and a Carnot efficiency of 8.3 %.the temperature difference in that part of the ocean.There is no point putting the power plant into a calm lagoon.
Some of the advertising pictures put the floating plant close to an island, but at such places the ocean is too shallow and there is not any real cold water even at the bottom. You need to move the plant into deeper waters.
A big plant need to be placed in a place with a good stream of warm water on the surface and a cold stream several thousand meters below surface. This is essential to main the temperature difference, since extracting (electric) energy tend to reduce
To extract more power on the oceans, some forms of evacuated tubular collectors could be used. These could float on waves and create temperatures well over 100 C, thus a Carnot efficiency over 27 % could be achieved.
And you could even use water as a working fluid :-).

This is a non-sequitur. The ocean provide a quasi infinite amount of
heat. Efficiency is only relevant if you supply the heat your self by
nuclear or chemical reaction.

There's a natural electric field above the ground, and people now and then raise money to use it.
There are a bunch of recurring money-raising schemes:
Trains in evacuated tunnels.
Supersonic passenger planes.
Vertical takeoff/land passenger planes. Very popular just now.
Electric airplanes.
Solar thermal towers
Ocean thermal power generation
River- and ocean-current power generation
Ocean wave power generation. Waves are free!
Airships
Cars powered by steam or Sterling engines. Or even batteries! Or hydrogen!
The Hydrogen Economy. Sunlight and water are free.
Flying cars
Rooftop residential wind turbines.
Gravity energy storage (solid mass, not pumped hydro).
Kite power generation
Bladeless wind generators of various sorts
Sailing ships
AI.
I may have missed a couple.
Electric motorcycles? Noiseless choppers will never sell.
Bowling ball energy storage?
Giant spring energy storage?

That's fraud,
There are a bunch of recurring money-raising schemes:
Trains in evacuated tunnels.
That actually makes sense, but only for extremely busy routes, which don't seem to exist.
Supersonic passenger planes.
Practicable, but turns out to be too expensive to be practical.
Vertical takeoff/land passenger planes. Very popular just now.
They've been around for ages, as helicopters. They seem to crash a little too often for comfort.
Electric airplanes.
It's not exactly recurring. More or less the same one has been flying around for years, and getting tweaked from time to time
https://www.nasa.gov/centers/armstrong/news/FactSheets/FS-034-DFRC.html
Solar thermal towers
They stopped being attractive when solar cells got cheaper and more efficient about a decade ago
Ocean thermal power generation
Cute idea but impractical.
https://www.google.com.au/books/edition/Engineers_Dreams/2l7bAAAAMAAJ?hl=en
River- and ocean-current power generation
It's called hydroelectric power and it is tolerably practical. Ocean currents don't seem to be fast enough to do the job.
Ocean wave power generation. Waves are free!
But they get big from time to time and break your machine.,
Airships
Perfectly practical, but a bit slow.
Cars powered by steam or Sterling engines. Or even batteries! Or hydrogen!
They all work. Batteries seem to work fine. Hydrogen seems to be a bit impractical, but the hydrogen economy enthusiasts like it.
The Hydrogen Economy. Sunlight and water are free.
Electrolysers aren't. You get about three times as much range out a battery than you get from the same amount of electric power turned into hydrogen.
Flying cars
Always a silly idea.
Rooftop residential wind turbines.
I've never seen one.
Gravity energy storage (solid mass, not pumped hydro).
Might work.
Kite power generation
Doesn't seem to work.
Bladeless wind generators of various sorts
Never seen one. Aerodynamics experts get turned on by the idea, but it seems to be more cute than practical.
Sailing ships
They do work, but not all that well.
AI.
Real artificial intelligence works fine, but only in specialised applications. As snake oil it does seem to suck in gullible suckers.
I may have missed a couple.
Electric motorcycles? Noiseless choppers will never sell.
Except that they sell fine, but not to hairy bikers.
Bowling ball energy storage?
Now you are being silly.
Giant spring energy storage?
It's called compressed air energy storage. If you have a big air-tight underground cavern it could work.

You are overly pessimistic.
The gaz car is practical even today because of the trillions that are invested.
If you imagine that kind of money projected on one of the ideas presented, you may be surprised.
