The idea .....
Send water on a 150 million kilometer pipeline to the sun to super heat it ... then pipe the steam back to power a turbine

Nuclear power is just steampunk with magic rocks.
Spicy rocks
I'm an EE by schooling and I've worked in both gas turbine and wind power. Photovoltaics blow my fucking mind. Everything else is just spinning magnets to extract power. PVs are insanely cool
Take a look at reverse electro-dialysis.
It's pushing thermal energy into electricity directly by the force of entropy.
The what now
Entropy is maximized by turning heat into electricity, so electricity appears on the device, as it gets cooler (by a tiny amount).
EDIT: I just noticed that you may be asking about the "reverse electro-dialysis" part :)
It's a process where fresh and salty water enter a machine, and they get mixed while generating electricity. It's the reverse of this:
https://en.wikipedia.org/wiki/Electrodialysis
That runs on the same conceptual machine.
(And oh, looks like it's written together.)
Your name makes me think you're about to lather your own naked body in vasoline, and hide inside the couch.
Personally, I like the mirror plants that use the suns energy to superheat salt.
And then use that to boil water. /s
For real, what China is doing with PVs is pretty fucking cool.
I actually don't know why people get so hung up on this. When you are making energy it's easiest to make heat, and boiling water through a turbine is a really efficient way to turn heat into motion and we're really good at doing it and turning motion into electricity. The fact that multiple ways of making heat exist is not surprising, the fact that different methods of making heat use the same, most efficient, well understood method for turning heat into electricity is even less surprising.
If we develop a more efficient way to turn heat into electricity it won't be "a new way to make energy" it will be "a new more efficient heat engine"
Because it feels archaic and inefficient, maybe?
We also have developed solar panels, wind turbines, hydro-electric dams as well as tidal/wave energy devices in the intervening years - so adding another method to boil water just feels “outdated”.
I’m not trying to cast judgement myself, just trying to explain that it feels like it’s just “vibes based”.
Take a look at a modern supercritical steam turbine, this thing can run on 600C steam. there's nothing archaic about it (it can be more efficient as a part of combined cycle)
Hydropower and windmills are older than steam
I had an idea for a dumb Star Trek meme, based on the episode where they explain how Romulan warp drives work, but extrapolating that to "it boils water and spins a turbine". Maybe one of the Star Trek memers can take this and run with it?
Three of your four examples are already outputting mechanical energy of motion so don't need the intervening conversion step provided by steam.
The problem is there’s an upper limit on how much useful energy you can extract from a heat engine.
1 - Tc/Th
The only 100% efficient heat exchanger has a cold side at absolute zero.
Where wind
Step 1: boil the ocean
Boiling water, obviously!
No, wind is spinning magnets. Everything except photovoltaics and fuel cells is spinning magnets. (Everything with boiling water is also spinning magnets)
You could always spin some wire and let the magnets stay still if you wanna be different.
It's also due to water being boiled. Just in a different, many steps removed manner.
Those systems are interesting, but also nightmares to build and maintain.
Supercritical co2 is a powerful solvent and can corrode most metals.this problem is worse when you increase the temperature.
Material scientists are working on it, but so far, the few test systems that have been built can't quite live up to the hype.
"I have an idea for a comic!"
"Is it you getting angry and sulking on the couch?"
What's the original comic?
Boil water and spin magnets
Well when you invent a new way to convert rotational energy into multi-phase AC please let us all know
