Except solar. And wind. And hydro.

[–] OrganicMustard@lemmy.world 146 points 3 weeks ago (5 children)

Some solar is also boiling water

[–] voracitude@lemmy.world 53 points 3 weeks ago (2 children)

And some of it is boiling salt!

Which then boils water, of course.

But some of it is electrons from photonic impact, no water involved! In the process of energy generation anyway. Statistically and perhaps somewhat ironically, the electrons from that photonic impact may well be used to boil water regardless... Humans just fucking love boiling water.

Isn't salt like the main bees knees these days?

[–] 24_at_the_withers@lemmy.world 10 points 3 weeks ago

I don't know, but the Ivanpah solar power station near Primm NV, which is a set of three molten salt towers is reportedly getting decommissioned, removed, and replaced with PV panels. Word is PV technology had improved in efficiency and stopped in cost enough that the whole molten salt thing is no longer economically viable, at least in comparison.

[–] voracitude@lemmy.world 9 points 3 weeks ago (1 children)

Oh, absolutely. It's very cool technology! Molten salt is corrosive as fuck, but that just kinda makes molten salt solar towers even more awesome.

[–] BandanaBug@piefed.social 4 points 3 weeks ago

I'm assuming ceramics to the rescue?

[–] brbposting@sh.itjust.works 3 points 3 weeks ago

:D

Something all the way down something

They did fix that pretty quickly, but what a classic mad scientist blunder that would turn a well meaning researcher into a villain in any action hero film.

[–] Redjard@lemmy.dbzer0.com 7 points 3 weeks ago

And some fusion is direct to current in coils. The z-pinch style approaches mainly.

that's why IMHO it's more important to classify the core coupling mechanism (e.g. photoelectric effect, electromagnetic effect) instead of classifying the total energy in -> energy out types.

[–] psud@aussie.zone 2 points 2 weeks ago

My local solar steam generator was shut down years ago as it was no longer worth testing direct reflector material anymore — even if they had gotten perfect reflectivity they couldn't compete with photovoltaics anymore

[–] xx3rawr@sh.itjust.works 38 points 3 weeks ago (4 children)

Expect for solar, it's all just flowy stuff through spinny stuff: wind, water, steam. GRAAAAAAAAAA

[–] bjoern_tantau@swg-empire.de 19 points 3 weeks ago

Good ol' mill.

[–] M137@lemmy.world 9 points 3 weeks ago

Spinny stuff is basically the universe on all scales, so it makes sense. And that's fucking cool, IMO.

[–] rockerface@lemmy.cafe 8 points 3 weeks ago

Solar is very tiny flowy stuff through very tiny spinny stuff

you forgot the electrochemical battery

[–] Skullgrid@lemmy.world 17 points 3 weeks ago

And wind.

wind is just the effects of premade steam

Condensed steam.

[–] judgyweevil@feddit.it 17 points 3 weeks ago (1 children)

It's still the same turbine shit

[–] anomnom@sh.itjust.works 9 points 3 weeks ago

It’s all turbines, but quite dissimilar turbines.

[–] fullsquare@awful.systems 4 points 3 weeks ago (1 children)
[–] I_Has_A_Hat@lemmy.world 5 points 3 weeks ago (1 children)

And waves/tidal, but now we're getting into the really niche types.

[–] hades@feddit.uk 3 points 3 weeks ago

i knew i was forgetting something

[–] Shanedino@lemmy.world 2 points 3 weeks ago (1 children)

Isnt hydro in a small part powered by steam just post condensation steam.

[–] phlegmy@sh.itjust.works 2 points 3 weeks ago

I do enjoy a nice glass of post condensation steam on occasion

[–] JakenVeina@midwest.social 2 points 3 weeks ago (3 children)

I dunno if "power plant" quite fits for solar and wind. Definitely for Hydro, though.

[–] JasonDJ@lemmy.zip 13 points 3 weeks ago* (last edited 3 weeks ago) (3 children)

"Power Plant" won't be a fitting term until we can generate electricity (at a viable scale) from chloroplasts.

And wouldn't that just be solar with extra steps?

fun fact: chloroplasts generate an electric potential across the cell membrane during photosynthesis. essentially, they have membrane proteins in their chloroplast membranes that push electrons from one side of the membrane to the other side whenever a photon hits the protein. It's essentially a natural photovoltaic cell.

That electric potential is then used to create ATP in nature, while we just directly extract the electrical power through cables.

[–] fartographer@lemmy.world 3 points 3 weeks ago (1 children)

Even better if you can use it to power a humanoid robot for a real world plant golem.

[–] TachyonTele@piefed.social 2 points 3 weeks ago

Isn't that the goal?

[–] JATtho@lemmy.world 1 points 3 weeks ago (1 children)

You should look at mitochondria:

  • The power plant of the cell.
  • Runs on a proton-gradient.
  • ATP synthase is essentially a molecular turbine and a generator.
  • oh. a turbine. Damm thing spins ~18000 rpm at medium throttle, pumping out elec- ATP. ATP.

Oops.. it's turbines all the way down.

[–] JasonDJ@lemmy.zip 1 points 3 weeks ago

runs on proton gradient

So I can launch it from Lutris?

[–] dublet@lemmy.world 2 points 3 weeks ago (1 children)

Why not?

The First Law of Thermodynamics: Energy Cannot Be Created or Destroyed

Fossil fuel power plants merely convert chemical energy into another type.

[–] JakenVeina@midwest.social 3 points 3 weeks ago

Just that "power plant" I think most people associate with large enclosed facilities that house power generating equipment, which doesn't quite describe wind and solar farms. Hence that most people refer to them as "farms".

[–] KittyCat@lemmy.world 2 points 3 weeks ago

And theoretically a massive proton exchange plant.

[–] HenriVolney@sh.itjust.works 1 points 3 weeks ago

Are these really power plants? I thought they were called field or farm or something else
