          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

            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.

          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.

        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.

            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.

          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.

            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”.

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

          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.

            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.

      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.

          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?

            gas generators based on internal combustion

            they heat air, afaik. hot gas expands -> mechanical movement moves magnets -> electromagnetism -> electric power.

            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.

        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
