      I swear Nuclear Reactors were designed by a chemist with a grudge against a physicist and engineer.

        So my general understanding is that you can use a magnet to create an electrical current. Its like it pushes the electrons, like a paddle pushing water. So they coil a bunch of wire around a magnet and rotate the magnet, which moves the electrons in the wire and that gets you electrical power. But you need something to push that magnet around, so you attach that to a big ass fan and use steam to push the fan. That’s your turbine. Nuclear power is just using a hot rock to make the steam. Hydroelectric power uses a river to push the turbine. Wind power is doing the same thing, just uhhh, with wind.

          Jesus christ this comment deserves a noble prize. Incredibly succinct explanation of something I didn’t get before.

        I’m not really sure how else you’d do it. The energy we can get out of fission is in the form of heat, and steam isn’t as compressible as just gas and it’s easy to make with just heat. Combine that with electromagnetism giving you electricity by spinning some magnets around some coils, and there you go.

        It’s probably possible to get some air hot enough and do some fancy convection work to get it to spin a rotor, but that’s going to be really inefficient.

        You could also use the heat to make materials glow and put a solar panel nearby, but that’s also going to be pretty inefficient.

          Hydro, wind, solar, and wave/tide energy capture are not.

          The crazy part is photovoltaics are the only power source that doesn’t spin something to make electricity. Truly an outlier.

              …and the fancy steam engine version of solar is probably greener to build that photovoltaics, since it’s basically just a boiler and some mirrors.
