        Not yet we’re not!

        Still plenty of nature to kill before humanity cannot survive in any capacity without corpo supply chains.

        If you’re breathing free air, drinking real water, and actual food can grow out of the ground we’re comparably in cyber paradise given how much worse AI spycraft and corporate ownership will worsen everything exponentially for the non-connected over the next decades

          I think there may be debate on this point. Climate change may be self perpetuating soon (if it isn’t already) due to thawing meant reserves, etc.

          I’m not sure if anyone in the scientific mainstream thinks that’ll push the climate to a point where we can’t survive, but that probably depends on our behaviour over the next few decades.

          I think by the end of this century we might hit a point of no return because the oil and gas have enough money to keep themselves from going under due to climate change.

        Could NOT get the nuclear power plant in Georgia off the ground for how long?

        Did it ever get finished?

        But when corporate wants it just fucking happens 🤡

          Let me preface this that I’m not a huge fan of nuclear, but I do like factual information.

          Could NOT get the nuclear power plant in Georgia off the ground for how long?

          If you’re talking about Vogtle, it took about 13 years and 14 years. (two reactors)

          Did it ever get finished?

          Yes. If you want to be specific the original two reactors were finished in 2008. The new work was for the other two reactors. That’s what took 14 years. Of the two new reactors, one started providing commercial power for the first time in June of 2023. The second new reactor only started providing commercial power in Feb of 2024.

          But when corporate wants it just fucking happens 🤡

          Different type of power plants between what is being discussed for Google and what was put in at Vogtle in Georgia.

          Vogtle was completing construction of an existing older design. Think of this like a bespoke tailored suit. It is crazy expensive, and only fits you.

          What most of these tech companies are going for is called Small Modular Reactors (SMR). Think of this as like buying a ready-to-wear suit off the rack. Its not nearly as fancy or as impressive (usually much smaller power generation), but its not custom made so its much cheaper.

      Businesses generating their own power is not anything new. The big auto manufacturers used to do it back in the day, and if you scale down the concept, every windmill (the grain grinding kind) and waterwheel built and operated for profit is the same thing. I’m just happy that Google is seemingly having their own built, instead of getting taxpayers to build it for them.

        Yeah, if this is what it takes to get new design nuclear facilities in the US, then I’m counting it a win, but I won’t count it either way until the watts come out. Who knows: if they run ok, an actual power company might even try one.

    The article mentions Kairos Power but doesn’t mention that their reactors in development are molten-salt cooled. While they’ll still use Uranium, its a great step in the right direction for safer nuclear power.

    If development continues on this path with thorium molten-salt fueled and cooled reactors, we could see safe and commercially viable nuclear (thorium) energy within our lifetimes.

    https://www.abc.net.au/news/2024-09-06/china-building-thorium-nuclear-power-station-gobi/104304468

    To my layman’s knowledge, using thorium molten-salt instead of uranium means the reactor can be designed in a way where it can’t melt down like Chernobyl or Fukushima.

    Edit: The other implication of not using uranium is that the leftover material is harder to make in to bombs, so the technology around molten-salt thorium reactors could be spread to current non-nuclear states to meet their energy needs and reduce reliance on coal plants around the planet.

    Crazy how quickly we’ve gone from “Nuclear is a dead technology, it can’t work and its simply too expensive to build more of. Y’all have to use fossil fuels instead” to “We’re building nuclear plants as quickly as our contractors can draft them, but only for doing experiments in high end algorithmic brute-forcing”.

    Would be nice if some of that dirt-cheap, low-emission, industrial capacity electricity was available for the rest of us.

        The cleanup for fossil fuels is an order of magnitude more expensive, and an order of magnitude more difficult. It also impacts so many things that its true cost is impossible to calculate.

        I’m aware of the issues with nuclear, but for a lot of places it’s the only low/zero emission tech we can do until we have a serious improvement in batteries.

        Very few countries can have a large stable base load of renewable energy. Not every country has the geography for dams (which have their own massive ecological and environmental impacts) or geothermal energy.

        Seriously, we need to cut emissions now. So what’s the option that anti-nuclear people want? Continue to use fossil fuels and hope battery tech gets good enough, then expand renewables? That will take decades.

      It’s almost like the brand spanking new tech to make small nuclear reactors are extremely cost prohibitive and risky, and to lower the cost someone needs to spend money to increase supply.

      I don’t think they’re even building many. The article uses the word “adopt” because they’re kinda reviving old power plants. Three Mile Island being one of them.

    I’ll be amazed if this ever comes to fruition.

    Generally speaking renewables + storage are the cheapest way of generating non-polluting power. After that there’s nuclear power and it’s much, much more expensive:

    After that, and even more expensive are SMRs. Also, they don’t actually exist yet as a means of generating power.

    From the article, “For example, it has already received the green light from the U.S. Nuclear Registry Commission (the first one to do so) to build its Hermes non-powered demonstrator reactor in Tennessee. Although it still doesn’t have nuclear fuel on-site, this is a major step in its design process, allowing the company to see its system in real life and learn more about its deployment and operation.”

      Generally speaking renewables + storage are the cheapest way of generating non-polluting power.

      At variable scale, based on time of year and weather. Nuclear is much better for base-load, particularly at the scale of GWs. You know exactly how much electricity you’re going to get 24/7, and the fuel costs aren’t exposed to a market that can vary by 150-300% annually.

      Nope, they have a partner that’s doing that and the partner is going to be providing small modular reactors. Although we are not sure according to the article whether Google is going to be running them directly to their data centers or whether they are going to be providing energy to homes and buying renewable energy credits or something. Either way, small modular reactors should bring down the price of nuclear.

    Growing from a broad research effort at U.S. universities and national laboratories, Kairos Power was founded to accelerate the development of an innovative nuclear technology …

    Kairos Power is focused on reducing technical risk through a novel approach to test iteration often lacking in the nuclear space. Our schedule is driven by the goal of a U.S. demonstration plant before 2030 and a rapid deployment thereafter. The challenge is great, but so too is the opportunity.

    So basically academics finding people to fund a large scale lab experiment, they want to get working by 2030. It sounds like they sold Google on an idea (for funding) and now have to move their idea from the lab to the real world. It does sound safer than water cooled plants of old at least.

    This is good news, relatively speaking.

    SMR technology is one of the most promising pieces of technological development in the nuclear power space.

    Standardized factory production and completely sealed, so refueling is only at the factory, never on-site. Their also, small, but scalable depending on the needs of each site.

    I’m not sure of the design this company is using, but I’m assuming they’re leveraging a fail safe reactor, as in, it requires properly running systems to generate fission, but if those systems fail, the fission process stops. There are no secondary systems that have to kick in, it’s a simple as either it’s running properly, or it can’t run it all.

    As opposed to systems like Chernobyl, or 3 Mile Island, that required separate active safety systems to guard against catastrophic failures. But if those failed, they’re backups failed, etc., well, meltdown.

          I guess I expect the national energy commission to still regulate the plant to ensure safety standards are the same between public and private.
