Every damn power plant is a glorified steam engine

[-] hades@feddit.uk 140 points 3 months ago

Except solar. And wind. And hydro.

[-] OrganicMustard@lemmy.world 130 points 3 months ago

Some solar is also boiling water

[-] stormeuh@lemmy.world 12 points 3 months ago
[-] fartographer@lemmy.world 3 points 3 months 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 6 points 3 months ago

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

[-] psud@aussie.zone 2 points 2 months 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 35 points 3 months ago

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

[-] bjoern_tantau@swg-empire.de 13 points 3 months ago

Good ol' mill.

[-] M137@lemmy.world 7 points 3 months ago

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

[-] Skullgrid@lemmy.world 17 points 3 months ago

And wind.

wind is just the effects of premade steam

[-] TachyonTele@piefed.social 6 points 3 months ago

[-] someguy3@lemmy.world 41 points 3 months ago

Condensed steam.

[-] judgyweevil@feddit.it 15 points 3 months ago

It's still the same turbine shit

[-] anomnom@sh.itjust.works 7 points 3 months ago

It’s all turbines, but quite dissimilar turbines.

[-] fullsquare@awful.systems 3 points 3 months ago
[-] I_Has_A_Hat@lemmy.world 4 points 3 months ago

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

[-] hades@feddit.uk 1 points 3 months ago

i knew i was forgetting something

[-] JakenVeina@midwest.social 2 points 3 months ago

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

[-] JasonDJ@lemmy.zip 10 points 3 months ago* (last edited 3 months ago)

"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 2 points 3 months ago

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

[-] gandalf_der_12te@discuss.tchncs.de 1 points 3 months ago

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.

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 2 points 3 months 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".

[-] Shanedino@lemmy.world 0 points 3 months ago

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

[-] phlegmy@sh.itjust.works 1 points 3 months ago

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

[-] magic_lobster_party@fedia.io 81 points 3 months ago

We’re living in a steampunk world after all

[-] Slovene@feddit.nl 33 points 3 months ago

I'm a steampunk girl

In a steampunk world

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

[-] Cethin@lemmy.zip 5 points 3 months ago* (last edited 3 months 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.

[-] TachyonTele@piefed.social 1 points 3 months ago

Aaackually...

That was a really cool explanation, thank you!

[-] mossberg590@lemmy.world 33 points 3 months ago

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

[-] MutantTailThing@lemmy.world 28 points 3 months ago

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

[-] ricecake@sh.itjust.works 5 points 3 months ago

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

[-] mossberg590@lemmy.world 6 points 3 months ago* (last edited 3 months ago)

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 -1 points 3 months 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 3 months ago

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 19 points 3 months ago
[-] thedirtyknapkin@lemmy.world 9 points 3 months ago

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?

[-] JasonDJ@lemmy.zip 2 points 3 months ago* (last edited 3 months 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 months ago
[-] fullsquare@awful.systems 2 points 3 months 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 2 points 3 months ago

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