    This is reminds me of a quote from one of the Encased loading screens.

    To paraphrase it “Power generation before was about turning a turbine with steam. Under the Dome we have this fancy technology that we use to…turn a turbine with steam.”

      Steam implies water! What if we used some OTHER phase-change working fluid? :D

      ||(No idea what, though. my question is implied with a playful tone and is at least 50% facetious; any actual discussion that might result would be little more than a pleasant coincidence)||

        You want to see weird water look up super critical boilers. That stuff was nasty. A regular steam leak will set things on fire. That stuff would explode a broom. We looked for the leaks with straw brooms. You can’t see steam in normal conditions. Only its effects.

        We can then use compressed CO2 in the place of steam to drive the turbine.

          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.

      We discovered a banger like 400 years ago and have held on tight until eight 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.

            The best solar panels are getting at or above the efficiency of converting nuclear heat to electricity (about 1/3) so they probably shouldn’t get that poor efficiency label.

              Some cells are getting 47%, which is ridiculous for a generator! The theoretical maximum efficiency for solar cell from the sun as it appears in the sky is about 68%, so that’s pretty good!

              However, how expensive is that cell going to be? How much maintenance does it need, and how fragile is the system once deployed? It’s very obvious that PV efficiency has beed skyrocketing recently, and I don’t thinks it’s stopping soon, but a commercial PV panel available today is just breaking 20% efficiency. Luckily, sunshine is quite abundant.

    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.
