      Yes. Water + spicy rocks. Everything else is solar power, which is also nuclear power, but with the spiciness in the sky instead.

        Fun fact. Coal plants release more radioactive materials than nuclear plants.]

        Except the ones that blew up. Those ones were extra spicy.

          Except, even then, an average coal plant will release more radioactive material over its lifetime than Fukushima did.

          It’s just Chernobyl that you have to top. And even then there are coal plants that come close.

          Now, it’s not apples to apples. Coal plants release uranium and thorium. Not ceasium and strontium.

          But yeah, never go swimming in a coal plant ash pit. For more than the obvious reasons.

            How many average coal plants per Chernobyl though. I suspect that number is surprising lower than the total number of coal plants.

          It’s all gravity in the end. Or probably middle but I don’t know why gravity, so that’s as far as I can reduce it.

          Everything we see around us is just hydrogen trying to get closer to the middle of the biggest hydrogen party it can find in the general vicinity. And we were all once part of at least one massive party that eventually got a bit out of hand when we all tried to get so close together we bounced off of a neutron star before it collapsed into a black hole.

          Unless you WANT your transistor to be this way and use it so you put an actual led inside the plastic as well to mess with (i.e. turn on and off) the transistor!

          Also I would argue that wind could also be considered ‘steam’ turning a turbine. It’s just vapour pressure ‘steam’ with a LOT of other pollutants which somehow increase the efficiency!

      We discovered a banger like 400 years ago and have held on tight until right about now with wind/solar/hydro.

      Still going to be using them geothermal/fission/fusion for at least another 100 years though.

          The only really new kinds are thermocouples (mostly garbage) and solar panels (poor efficiency, but abundant fuel).

          Some fusion might end up using magnet pumping, which is basically just a plasma powered piston.

            Don’t skip the betavoltaic battery, (or the brand-name: Betacel), which turns beta-radiation directly into electricity. They used them in the 70s to power pacemakers, since batteries were kinda shit back then, and implanting Prometium into people is just too epic not to do.

            Nowadays we have tritium-decay betavoltaic batteries, on satellites, buried or underwater sensors and probably some too secret military stuff.

              Ooo, good call.

              There’s also radioisotope piezoelectric generators, where the electrons are caught by a cantilever and then released in regular pulses. An electron waterwheel if you will.

        There’s also fuel cells, where fuel is not burned to create steam to move something, but combined with oxygen in a different way (the end products still being the same) so the electrons shuttled around during this reaction can be utilised as electricity. Think of combustion as oxidation of your fuel, the oxidation meaning that you (among other things) move electrons from the fuel to oxygen. In combustion, unfortunately you can’t access the electrons directly, as they are always stuck in the chemical bonds of the molecules, that’s why we take the detour via heat/mechanical - the steam engine. The fuel cell now separates fuel and oxygen, and thus divides the combustion reaction into two parts that happen at opposite sides of the cell. Those sides are divided by a membrane that does not allow the electrons to transfer across, so they need to take a detour through an electric circuit, in which we can harvest them as electrical power.

        I always found it really fascinating that fuel cells are the only other technology than solar where the electrons we use as electrical power are more or less directly generated as opposed to the detour via a generator. Unfortunately, fuel cells are still a very niche technique.

    Nearly all power generation comes down to boiling water to steam which spins a turbine.

    I can only think of two common exceptions off the top of my head. Solar is an exception and Hydro power is an exception ironically, that usually uses the vertical difference and gravity to spin the turbine.

        I’ve never heard of Hydro power boiling water. Usually hydro power is natural or pumped storage.

        You’re just taking water from an upper reservoir and dropping it to a downstream river. Either a naturally-filled reservoir/lake, or a pumped storage reservoir where you use other cheap power during low usage periods to pump that water to a higher reservoir to utilize later. The pump doesn’t heat the water, it just moves it uphill to utilize later, like the Taum Sauk Hydroelectric Power Station in Missouri.

          I know that… I was taking liberties to take hydroelectric power to its furthest logical extension by saying that the sun is evaporating (boiling) the water, it goes through the water cycle, it is deposited atop mountains or further upriver, and it then flows back down through the hydroelectric stations.

        Oh yea! I forgot about that one! It’s starting to be used a lot in implantable medical devices to generate a small current. There was also that thing a few years back that was trying to use it to generate power from waves/tides; not sure if that actually got past the proof-of-concept stage though.

    I heard that somewhere in the US there were parts of a nuclear power plant being delivered by steam train. So that’s basically one steam engine supplying another! (^^,)

      Given that the first commercial nuclear power plants in the US were coming online in the late 1950s, that’s entirely possible. Steam trains were well on their way out by then, but there were still a few hauling freight around.

      Fun adjacent fact: even when the British Empire had moved off of wind sails and into coal, those coal ships didn’t have the range to possibly cover the entire Empire. Coal stations were setup around the world, and the coal had to be transported by sail. The previous technology helps get the next generation technology going.

    plus a side of extra spicy landfill

    https://en.wikipedia.org/wiki/Hanford_Site

    “safe nuclear”: Between 1944 and 1971, pump systems drew as much as 75,000 US gallons per minute (4,700 L/s) of cooling water from the Columbia River to dissipate the heat produced by the reactors. Before its release into the river, the used water was held in large tanks known as retention basins for up to six hours. Longer-lived isotopes were not affected by this retention, and several terabecquerels entered the river every day. The federal government kept knowledge about these radioactive releases secret.
