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. permalink fedilink source parent hideshow 1 child comment replies: [–] TachyonTele@piefed.social 1 point 9 months ago Aaackually...

Lower pressure, higher efficiency, and I believe less reactive in the event of an uh-oh. permalink fedilink source parent hideshow 2 child comments replies: [–] mossberg590@lemmy.world 6 points 9 months ago* (1 child) 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. permalink fedilink source parent hideshow 1 child comment replies: [–] ricecake@sh.itjust.works -2 points 9 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. permalink fedilink source parent [–] partial_accumen@lemmy.world 9 points 9 months ago (5 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. permalink fedilink source parent hideshow 5 child comments replies: [–] imsufferableninja@sh.itjust.works 19 points 9 months ago (3 children) Hydro is liquid steam permalink fedilink source parent hideshow 3 child comments replies: [–] thedirtyknapkin@lemmy.world 9 points 9 months ago (1 child) 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? permalink fedilink source parent hideshow 1 child comment replies: [–] JasonDJ@lemmy.zip 2 points 9 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. permalink fedilink source parent [–] Agent641@lemmy.world 1 point 9 months ago Molten ice. permalink fedilink source parent [–] fullsquare@awful.systems 2 points 9 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 permalink fedilink source parent [–] Zaphod@discuss.tchncs.de 2 points 9 months ago I watched a video a while ago about a new approach to fusion which uses induction iirc https://youtu.be/uRaQLZaaHWo permalink fedilink source parent

The First Law of Thermodynamics: Energy Cannot Be Created or Destroyed Fossil fuel power plants merely convert chemical energy into another type. permalink fedilink source parent hideshow 1 child comment replies: [–] JakenVeina@midwest.social 2 points 9 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". permalink fedilink source parent

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. permalink fedilink source parent hideshow 1 child comment replies: [–] TachyonTele@piefed.social 1 point 9 months ago Aaackually...
