Every damn power plant is a glorified steam engine

    Except solar. And wind. And hydro.

    Some solar is also boiling water

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

    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.

    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

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

    "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.

    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".

    We’re living in a steampunk world after all

    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.

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

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

    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.
