Very excited for physics-defying limitless energy though. The last couple of times the science people invented it it must have gotten hung up on red tape or something.

Retraction: Upon further testing it was discovered the physic defying battery, "laboratory electrical wall socket" wasn't storing vast amounts of electricity, but was instead transferring it through from a yet to be determined location.

As usual, the articles themselves are nowhere near as baseless in their claims as the clickbait headline but also way more mundane and quite unremarkable for the sort of people that get drawn in because of the headline and not for the underlying developments.

Germany still intent on bringing back coal: https://www.reuters.com/business/energy/germany-approves-bringing-coal-fired-power-plants-back-online-this-winter-2023-10-04/ quote:Germany's cabinet on Wednesday approved putting on-reserve lignite-fired power plants back online from October until the end of March 2024, the economy ministry said, as a step to replace scarce natural gas this winter and avoid shortages. Yay lignite. So much cleaner than nuclear power.

No one cares anymore. I was always a strong proponent of nuclear energy. But the fact that those things got turned off is a political decision which is straight up irreversible. We live in the world we have and have to deal with the situations as they are and not as they should be. I'm not saying that any of this is smart, but this is just what's happening and we have to accept it by now. Crying about those obvious implications feels like Pro-Brexiters who complain about import tariffs some years after their vote. Do you guys think it would have gone any different if there was a nuclear referendum first? Maybe if they waited a few months after the earthquake? Germans are just straight up idiots when it comes to this topic. Even people I consider quite smart otherwise. And it's not just some astroturfed propaganda network either. I will always disagree with that decision, but I have to admit that the politicians were absolutely following the voice of the people there. cant cook creole bream fucked around with this message at 00:37 on Oct 8, 2023 |

I do think the development of nuclear is still possible. "It's irreversible, stop talking about it" is basically the number one strategy of the fossil fuel rhetorical playbook, implying and demanding that others accept the futility of efforts toward change.

have you guys heard of utilizing energy during the day to move brick like things or heat metal? that way you can have that potential energy be used during non sunlight hours. For example, "when a thermoelectric material is exposed to a temperature gradient — for example, one end is heated, while the other is cooled — electrons in that material start to flow from the hot end to the cold end, generating an electric current" bricks that have been raised during sunlight can be dropped to create electricity (USER WAS PUT ON PROBATION FOR THIS POST)

German nuclear killed* itself last spring. When the last shutdown shoved Nuclear into the news cycle all visible pro-nuclear organisation declared that being pro-nuclear is synonymous with climate change denial (specifically the "markets will fix things if we deregulate", variant). It is very unlikely that Germany will have a noticeable voting block that believes in pro-nuclear state action against climate change for the next decade. Funnily the Greens are currently the most likely party to increase nuclear usage in Germany, through their proposed investments into EU grid interconnection. *and by killed I mean the corpse started twitching due to gas-shortage and it used the opportunity to put a new stake in its heart in the hopes of helping the fossil industry with it. TheMuffinMan posted:have you guys heard of utilizing energy during the day to move brick like things or heat metal? Rising bricks suck. Big flywheels are generally better and are being used to jump-start fusion experiments and other high energy physics and were tested for smoothing EV fast-charger load. But they all are getting replaced by supercaps. And all of those are not great once your load time exceeds an hour. Heating things is being done for heating. You heat a heat tank during the day (solar driven heatpump or direct sunlight) and use the heat tank to heat your house during the night. To a limited extend this can be used to store heat in summer for winter, but that is fairly experimental. VictualSquid fucked around with this message at 09:56 on Oct 8, 2023 |

QuarkJets posted:In this analogy you've created the people who are pro-nuclear also voted for the nuclear power plants to close (???) This back and forth cost billions in compensation. The CDU and FDP were also the ones who then did nothing in order to compensate for the back and forth on nuclear power except to ignore renewables and support the shift to gas (along with the SPD) instead. When this blew up, they then blamed the Greens, because ... Their only solution to the problem was then to try to go back again against their own back and forth and try to argue that actually they never did support the back and forth they did and that the insufficient solution they were willing to go with would magically solve all problems. So the analogy does work quite well.

The CDU was in power when the shutdown was decided and it was and arguable still is the party most closely associated with nuclear power. And 90% of the times when someone brings up the Atomausstieg as a bad thing it is as part of an attempt to defend the CDU from some green criticism, and to call for their re-election. This year it is mostly about car culture.

its funny how the actually people in Fukushima*, other places in Japan* near/nearer, or South Korea* , actual stake holders that live with da supa death atoms have a warmer relation to nuclear than German other countries that I assume are in the middle of their tectonic plates or are landlocked countries. so relatively resistant to earthquakes or super waves. * other than that "waste" water issues, but Japan unlike NY is still doing it. good job.

Actually I think the lack of such things make Chernobyl seem massive. As in, it was arguably the worst disaster to impact the whole country between 1945 and 2021. And I do expect the new comparison with the rona to move a lot of people from anti-nuclear to neutral. But the root cause of the strong anti-nuclear sentiment in Germany has always been the embarrassing stupidity of the pro-nuclear lobby, imo. Especially in choosing their political alliances. For example by continuing to support the CDU and the fossil industry despite all the backstabbing.

Was listening to the latest VOLTS podcast, and this time there was an interview with the CEO of a thermal battery company called Antora. Apparently they launched their first commercial-scale system and it is really fascinating. An easily mass produce-able intermodal container sized thermal battery that can output both heat and electricity on demand and at a controlled rate. Made from dirt cheap carbon heated to more than 2000 degrees C that is literally radiating energy like a small sun, the light hitting special water cooled and IR mirror backed PVs that destroy all tech efficiency records to date and also hitting pipes that heat water to steam via controllable shutters at the periphery.  This stuff is bonkers. Sadly I can't find a transcript for it, here is the pod though, blew my mind. quote:A super-battery aimed at decarbonizing industry Dante80 fucked around with this message at 21:03 on Oct 9, 2023 |

It really showed change was possible.

https://interestingengineering.com/innovation/desk-sized-turbines-power-10000-homes "The turbine's job is to use water as a thermal medium in power cycles. However, if one were to change the medium itself, the turbine could be much smaller in size. Enter carbon dioxide as a working fluid, and the turbines can be significantly downsized."

Seems to be really stupidly worded and I might be thus completely misunderstanding it but the point is that a supercritical CO2 gas turbine is more efficient than a water gas (Steam) turbine? I guess through increased density and possibly easier operating temperature regimes? If it could somehow make it so that low grade heat is useful, then solar thermal plants would indeed benefit.
