Nearly all power generation comes down to boiling water to steam which spins a turbine.

I can only think of two common exceptions off the top of my head. Solar is an exception and Hydro power is an exception ironically, that usually uses the vertical difference and gravity to spin the turbine.

Wind turbines also.

But some solar does focus it on a tower to make steam to drive a turbine.

There are gas turbine generators that directly use shaft power to generate electricity

[–] TranscendentalEmpire@lemm.ee 12 points 1 day ago

Yeah, who would have guessed that modernity was invented by someone who stuck magnets to a fidget spinner and strapped it to a boiler.

One could even argue that hydro power is just boiling water, letting it condense, and then letting it spin a turbine

[–] halcyoncmdr@lemmy.world 3 points 1 day ago (2 children)

I've never heard of Hydro power boiling water. Usually hydro power is natural or pumped storage.

You're just taking water from an upper reservoir and dropping it to a downstream river. Either a naturally-filled reservoir/lake, or a pumped storage reservoir where you use other cheap power during low usage periods to pump that water to a higher reservoir to utilize later. The pump doesn't heat the water, it just moves it uphill to utilize later, like the Taum Sauk Hydroelectric Power Station in Missouri.

They were speaking of the water cycle. It's the naturally-filled part. Not necessarily boiled, but evaporated.

[–] subtext@lemmy.world 3 points 1 day ago

I know that… I was taking liberties to take hydroelectric power to its furthest logical extension by saying that the sun is evaporating (boiling) the water, it goes through the water cycle, it is deposited atop mountains or further upriver, and it then flows back down through the hydroelectric stations.

~~Nuclear~~ power is just boiling water

I bet there is a way more efficient way to harness it that we are just missing too lol

[–] P00ptart@lemmy.world 1 points 17 hours ago

I'm kinda surprised that nobody has harnessed our magnetic field to build a power source. Or at least tried. I have no idea how it could work, and I may be dumb as shit for this. But I feel like it could be possible if we had another 500 years left of society.

Errich, is the refrigerator running? This is Mike Hunt, and he's a rich.

There are some fusion designs that use direct energy conversion.

Some work went into fission designs as well.

Nuclear power is the refining distilling and enriching of uranium into unstable isotopes and higher elements, boiling water is one small step in converting nuclear energy into electrical energy.

[–] Rolder@reddthat.com 7 points 1 day ago

But it’s one of the most important steps because it’s where the actual electricity comes from.

I heard that somewhere in the US there were parts of a nuclear power plant being delivered by steam train. So that’s basically one steam engine supplying another! (^^,)

I can’t seem to find an article about it anywhere, so it might be an urban legend :(

And then there are thermonuclear generators
