Every damn power plant is a glorified steam engine

[–] hades@feddit.uk 109 points 8 hours ago (6 children)

Except solar. And wind. And hydro.

[–] OrganicMustard@lemmy.world 100 points 8 hours ago (3 children)

Some solar is also boiling water

[–] voracitude@lemmy.world 27 points 5 hours 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.

[–] blazeknave@lemmy.world 5 points 2 hours ago (2 children)

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

[–] voracitude@lemmy.world 3 points 2 hours 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 1 points 31 minutes ago

I'm assuming ceramics to the rescue?

[–] 24_at_the_withers@lemmy.world 1 points 31 minutes 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.

:D

Something all the way down something

[–] stormeuh@lemmy.world 10 points 8 hours ago (1 children)
[–] fartographer@lemmy.world 1 points 36 minutes ago

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 5 points 5 hours ago

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

[–] xx3rawr@sh.itjust.works 28 points 7 hours ago (3 children)

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

[–] bjoern_tantau@swg-empire.de 11 points 7 hours ago

Good ol' mill.

[–] rockerface@lemmy.cafe 4 points 5 hours ago

Solar is very tiny flowy stuff through very tiny spinny stuff

[–] M137@lemmy.world 4 points 1 hour ago

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

[–] Skullgrid@lemmy.world 11 points 7 hours ago

And wind.

wind is just the effects of premade steam

[–] someguy3@lemmy.world 38 points 8 hours ago

Condensed steam.

[–] judgyweevil@feddit.it 12 points 8 hours ago (1 children)

It's still the same turbine shit

[–] anomnom@sh.itjust.works 4 points 6 hours ago

It’s all turbines, but quite dissimilar turbines.

[–] fullsquare@awful.systems 3 points 3 hours ago (1 children)
[–] I_Has_A_Hat@lemmy.world 4 points 2 hours ago (1 children)

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

[–] hades@feddit.uk 2 points 2 hours ago

i knew i was forgetting something

[–] JakenVeina@midwest.social 2 points 6 hours ago (3 children)

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

[–] JasonDJ@lemmy.zip 8 points 5 hours ago* (last edited 5 hours ago) (1 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?

[–] fartographer@lemmy.world 1 points 33 minutes ago

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

[–] dublet@lemmy.world 1 points 5 hours ago

I dunno if “power plant” quite fits for solar and wind

Why not?

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

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

We’re living in a steampunk world after all

[–] Slovene@feddit.nl 31 points 8 hours ago

I'm a steampunk girl

In a steampunk world

It's not a big big thing if you steam me

[–] Cethin@lemmy.zip 4 points 4 hours ago* (last edited 4 hours ago)

I'm going to be this person I guess, but the defining trait of steampunk isn't the use of steam alone. It's that energy is transfered by delivering steam to where it's used, rather than using it in-place to crested electricity. This means that steampunk machines operate off of some kind of kinetic energy, rather than electrical energy.

Basically, computers (and everything else) are spinning gears, not silicon.

[–] mossberg590@lemmy.world 29 points 8 hours ago (2 children)

Readily available, low boiling point, non corrosive (relatively), and ecologically safe. What more do you want?

[–] MutantTailThing@lemmy.world 27 points 8 hours ago

Also a ridiculously high heat capacity. It does make sense.

[–] ricecake@sh.itjust.works 4 points 5 hours ago (1 children)

Molten salt. Lower pressure, higher efficiency, and I believe less reactive in the event of an uh-oh.

[–] mossberg590@lemmy.world 3 points 4 hours ago* (last edited 4 hours ago) (1 children)

The molten salt is used as the first step. It then makes steam through a heat exchanger. Molten salt is safer next to the actual reactor because water is not a good coolant in case of emergency.

[–] ricecake@sh.itjust.works 0 points 2 hours ago

Oh, I was just joking around. What my water system is missing is molten salt.

Although for the sake of preposterousness, I'm going to suggest we use the molten salt to turn a giant water wheel.

[–] partial_accumen@lemmy.world 9 points 8 hours ago (2 children)

Hydro isn't. Nor is solar photo voltaic, wind, or tidal, but yeah, nearly everything else is. In a combined-cycle natural gas or diesel plant half of the power generated isn't steam power, but the other half is.

[–] imsufferableninja@sh.itjust.works 16 points 8 hours ago (2 children)
[–] thedirtyknapkin@lemmy.world 10 points 8 hours ago (2 children)

aah, but it didn't say steam, it said boiling water.

smaller gas generators based on internal combustion engines don't boil water though, right?

[–] baines@lemmy.cafe 3 points 7 hours ago

boiling just makes the water move, hydro just cheats

[–] JasonDJ@lemmy.zip 1 points 5 hours ago* (last edited 5 hours ago)

Electromagnetic induction.

Basically electric motor in reverse...instead of electricity powering the motor, the motor powers electricity.

But the trick is in "what spins the motor". In the case if ICE generators, it's usually a pulley off the crankshaft.

Or it could be moving water.

[–] Agent641@lemmy.world 1 points 3 hours ago
[–] fullsquare@awful.systems 2 points 3 hours ago

for ccgt it's more like 2/3 for gas turbine, 1/3 for steam turbine split, even more uneven for diesel/steam because diesel exhaust is much colder

[–] Zaphod@discuss.tchncs.de 1 points 27 minutes ago

I watched a video a while ago about a new approach to fusion which uses induction iirc https://youtu.be/uRaQLZaaHWo
