                There currently are processes to deal with them, multiple companies are working on the problem.

                Current solutions include shredding them and reconstituting into some sort of alternative building material, chemically separating the parts of the composite and creating recycled resin, and mechanically separating and sorting apart the different materials which are then recombined for alternative use.

                This is a good place to look at recent american efforts, but there is more recent information available elsewhere: https://www.energy.gov/eere/wind/wind-turbine-materials-recycling-prize

          Of course there are, because mining and construction are powered by the old stuff. That doesn’t seem like a compelling downside to building things that generate clean power, since that’s a downside to building literally anything.

            What’s the grand scheme of things mean to you? If we average it out over 40 years? How does nuclear even fit in when solar and wind are cheaper? Nuclear plants don’t provide on demand energy to fill in the gaps, they provide energy constantly.

            The only reason it works for microsoft is because they plan to use all that energy consistently. But besides that why should we trust a for-profit company to do anything safely in the first place? Do we have a long history of companies being regulated well or self-regulating well?

              The nuclear industry is heavily regulated by the government via the NRC, but they impose even stricter regulations upon themselves. Solar and wind are cheaper, but they are less reliable. A grid comprised of a mix of solar and wind, bolstered by nuclear is the most effective and least environmentally harmful option that we currently have.

        Expecting corporations to “solve important problems in the world” is foolish though. You should expect your government to tax them fairly so that they can work on people problems and maybe it takes corporations a few years longer to afford their own fleet of nuclear power stations.

      I agree, and it is possibly the only good thing to come out of AI.
      Like people asking “why do we need to go to the moon?!”.

      Fly-by-wire (ie pilot controls decoupled from physical actuators), so modern air travel.

      Integrated circuits (IE multiple transistors - and other components - in the same silicon package). Basically miniaturisation and reduction in power consumption of computers.

      GPS. The Apollo missions lead to the rocket tech/science for geosynchronous orbits require for GPS.


      This time it is commercial.
      I’d rather the power requirements were covered by non-carbon sources. However it proves the tech for future use.

      For a similar example, I have a strong dislike of Elon Musk. He has ruined the potential of Twitter and Tesla, but SpaceX has had some impressive accomplishments.

      Google are a shitty company. I wish the nuclear power went towards shutting down carbon power.
      But SOMEONE has to take the risk. I wish that someone was a government. But it’s Google. So… Kind of a win?

    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.

    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.

        It’s almost like you have no clue what you are talking about lol. The global population growth for the last 30 years is 50%, while the global GDP growth is 500%. Not only that but the wealth inequalities in the world have been steadily rising for the last 60 years. In the US alone (that we have data on) the wealth of the bottom 80% has been roughly stagnant since the 1990s while that of the top 1% has skyrocketed - it’s basically them that have absorbed this economic growth profit.

        So yeah, you got a lot of confidence in things you clearly don’t know about.

            You have to understand that GDP and energy demands are intrinsically tied. That’s a fact, both theoretically and empirically verified with historical data. When the GDP rises, energy demands rise. And the reason why energy demands rise is not to meet people’s needs but because the 1% seek to increase GDP (through individual corporation stock values) which in turn increases their profits, since like I said they absorb all of it. That is why it is relevant, because it’s a matter of wealth accumulation by the 1%, not because people need more energy. That is backed both by the fact that the common people don’t get anything out of the increase in economic production(the bottom 80% like I’ve said have had a stagnant wealth since the 1990s in the US, although the global GDP has risen 5-fold, even though the population has risen and hence the people in that 80% has risen as well) and by the fact that the population increase has been just 50% and the increase in wealth ten times that.

              So our population has increased by 50% and you expect our energy demands to stay the same or decrease? All countries have increased energy production, including China, I’m not sure why you’re making this sound like a US centric problem.

                What in the world do you mean “you expect our energy demands to stay the same or decrease?”. What does expect mean??? I don’t expect anything, I’m stating what needs to be done if we want our planet to remain habitable…have you heard about climate change or…? Also how do you keep ignoring the fact that our wealth has increased by 500% in the last 30 years and the 1% gets all the profit? We don’t need to increase our economic activities for all the people to be able to live comfortably, we need distribute wealth fairly and when we get to a point where everyone can live well, (in the West we are way past that point) then we need to scale down unnecessary economic activities, if we want to meet the scientific guidelines to avoid the 3 degrees by the end of the century, which would spell absolute irreversible disaster.

                I never said it’s a US problem, and I didn’t make it sound like so, I was only using some data from the US for convenience. It’s a worldwide problem, but the US dictates the trajectory and policies of a very big part of the world including Europe, Canada, Australia and the gulf countries, all of which are essentially controlled by them. Also the US has by far the most CO2 emissions historically, making that country the single biggest contributor to climate change, again, by far. So it bears the biggest responsibility of any country. But you are right, it’s a worldwide problem.

      The other side of the coin is that AI currently uses more power than is produced by all renewables across the globe annually. So at least they’ll be offsetting that, which would be a net positive.

      And it seems like Google’s funding will help advance safer and more modern nuclear plant designs, which is another win that could lead to replacing coal plants in many countries with small scale reactors that don’t run on uranium.

          For what it’s worth, many, maybe most (sorry, can’t be bothered to look up the stats right now) nuclear plants in the US are already owned by some publicly traded company beholden to its shareholders who expect it to turn an ever increasing profit for them.

          Not that it gives me the warm-fuzzies that that’s the case, but it’s not quite as big of a departure from the current situation as you’re making it out to be.

        Yes it’s obviously better than using fossil fuels, nobody’s arguing that. What I’m talking about is the direction the global economy and the people making the decisions are taking.

        No matter how much nuclear energy you use, you are still putting a lot of additional strain on the environment. It’s not just the CO2 emissions that matter, that’s just one of the problems. It’s the increase in extracted materials for data centers, reactors and nuclear fuel, which causes the destruction of multiple ecosystems and the contamination of waters and soil from the pollutants produced(even radioactive waste in the uranium case).

        It’s also that Google could have been taxed more(I’m sure they can take it) and the money the government gained could be directed to investments on nuclear plants that would actually replace fossil fuels instead of adding energy demands on top of them. Because the fact of the matter is that in 2024 we categorically cannot be talking about not increasing fossil fuel consumption, we have to be talking about how to reduce emissions drastically every single year and why we are already tragically behind on that regard.

    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.

    As opposed to systems like Chernobyl, or 3 Mile Island, that required separate active safety systems to guard against catastrophic failures.

    Nuclear has never been profitable without massive government subsidies and guarantees, and Google Kairos too will either manage to collect those or lose money.

    It’s unclear how Google and Kairos set up the deal — whether the former is providing direct funding or if it just promised to buy the power that the latter generates when its reactors are up and running. Nevertheless, Kairos has already passed several milestones, making it one of the more promising startups in the field of nuclear energy.

    I guarantee you, they are shouldering on none of the risk (like the Chinese and French at Hinkley Point), and this startup will be going down.

    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.”

      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.

          Well one easy one, in my country it is that nuclear plants need to emit zero radiation from their core, like nothing. This is incredibly expensive to achieve, a more sensible value would have been similar or less than normal background radiation.

          Nuclear has a lot of advantages that are really low hanging fruit of producing safe clean energy that is perfect for a grids baseload.

            Also, there are strong arguments that we no longer need baseload generation and in fact it’s detrimental:

            "No new nuclear or coal plants may ever be needed in the United States….

            Wellinghoff said renewables like wind, solar and biomass will provide enough energy to meet baseload capacity and future energy demands. Nuclear and coal plants are too expensive, he added.

            “I think baseload capacity is going to become an anachronism,” he said. “Baseload capacity really used to only mean in an economic dispatch, which you dispatch first, what would be the cheapest thing to do. Well, ultimately wind’s going to be the cheapest thing to do, so you’ll dispatch that first.”…

            “What you have to do, is you have to be able to shape it,” he added. “And if you can shape wind and you can effectively get capacity available for you for all your loads.

            “So if you can shape your renewables, you don’t need fossil fuel or nuclear plants to run all the time. And, in fact, most plants running all the time in your system are an impediment because they’re very inflexible. You can’t ramp up and ramp down a nuclear plant. And if you have instead the ability to ramp up and ramp down loads in ways that can shape the entire system, then the old concept of baseload becomes an anachronism.”"

              South Africa, you can read up on us if you want to learn about a country that really fucked up its energy supply, but that is a different story.

              You do need a baseload, this is not something an argument of saying we do not really need a baseload can wish away, industries that run 24/7 like a smelting operation where if you cannot shutdown, or hospitals or traffic lights, there is a certain percentage of baseload that has to be generated.

              Solar and wind are amazing and I really wish to see these systems play a major role in power generation, but you say the nuclear and coal plants are very inflexible. I do not know who this guy is but Nuclear and coal can very easily ramp up their power generation, both these are basically steam engines, both nuclear and coal can very quickly heat up and generate a lot more steam that powers generators, like an car engine but more accurately a steam train that you give more power to go faster. Solar and wind cannot ramp up on their own, cannot ask the wind to blow harder or the sun to shine brighter suddenly when the system requires it, they need costly backup systems like methane peaker plants or energy storage, be it batteries, pumped hydro, hydrogen electrolysis the list goes on. These things added to solar and wind plants are usually not allocated to the cost of generation, a total cost of generation including these additional backup systems are a better indicator of solar and wind systems cost.

              Now what about waste. I agree coal is messy and is causing global warming and needs to be phased out. But nuclear waste is a solved problem, it has been for decades, the spent fuel is usually stored deep underground where it will never interact with the world again. Solar on the other hand, if it costs about $20-$30 to recycle a panel but like $1-$3 to send it to a waste dumps, what do you think will happen to the solar panels. https://hbr.org/2021/06/the-dark-side-of-solar-power Harvard business did an article about how solar recycling has really been a point of weakness, where nuclear we have set guidelines on how to environmentally and safely dispose of nuclear waste currently. I am willing to bet you the environmental impact from pollution from nuclear, including all the disasters will be negligible compared to the waste impact from solar panels and batteries currently.

              So my point is not to dismiss solar or wind, really where wind and sunshine are naturally plentiful it will be a waste not to harvest these resources, just like where geothermal resources are available it will be wasteful not to utilise it.

              But nuclear, even with its high initial capital cost and long build time, still does provide energy cheaply and will last for a lot longer than solar panels and wind turbines, nuclear can be easily and quickly ramped up or down depending on the load required.

              Yes. But a single flight across the US exposes people around 4 times ground level background radiation.

                Sure, it’s a negligible amount but OP was saying that nuclear would be competitive on cost if only red tape wouldn’t keep pushing the price up. Their contention was that less shielding would substantially lower the price of new nuclear but so far I’ve not seen anything to support this argument.

      No, EVs alone require 10 times the current installed energy production. We’re not even close. Expect energy rates to quadruple. The price will increase until people can’t afford the commute with their entire day’s paycheck.

        EVs alone require 10 times the current installed energy production.

        No they don’t.

        The UK national grid estimates there needs to be a 4-5% increase each year, for roughly 15 years. That’s achievable.

        The US won’t be too different.

        Expect energy rates to quadruple

        Why quadruple. Where are you getting this from?

        The price will increase until people can’t afford the commute with their entire day’s paycheck.

        They obviously won’t.

          Fossil fuel power plants don’t count. EVs running of fossil fuel make no sense. Remove them from the equation and my prediction becomes extremely optimistic.

            EVs are currently running partially on fossil fuel just fine and generating less pollution than ICEs because power plant efficiency is still better than combustion engine efficiency.

              That is nowhere near enough. It’s 33% versus 40% difference between co2/kWh . we need zero co2/kWh or else it’s all a waste of time.

              It’s only acceptable if we are transitioning to zero emission grid. If we stay on natural gas then it won’t even move the needle.

                We are transitioning towards it, but in the meantime, switching to EVs still reduces CO2 output and because the grid is getting cleaner, that means EVs get cleaner even after being manufactured and sold, whereas ICEs can only get cleaner through R&D and only get worse over time as they age (once they start burning oil, etc)

                  A few percentage points reduction in co2 emission isn’t going to move the needle. The whole grid has to shutdown fossil fuel energy production for this transition to make sense.

            In what world don’t they count?

            They can power EVs. And running an EV on fossil fuel electricity is still far less polluting than running a petrol or diesel car.

            One large generator at its most efficient setting is far more efficient than tens of thousands of small ones starting from cold multiple times per day, that aren’t necessarily maintained well, and are constantly going through their rev range.

            Where are your sources for any of what you’re saying?

              No , if you run EVs off a grid fossil fuel generator, that’s the difference between 33% and 40% efficient. It’s not enough to move the needle. It doesn’t even pay for itself in terms of emissions.

              The energy source absolutely has to be ZERO emissions as well. If not then it’s just climate cope.

                What the hell are you talking about? That’s not how people charge EVs.

                EVs on their own are typically 90%+ efficient. Although some are as low as ~85%.

                Even running on a generator, though, they’d still be more efficient than any ICE engine found in a car, aside from a Formula 1 engine.

                EVs are far cleaner, even if ran on a fossil fuel energy grid.

                  fossil fuel power plant are tops 40% efficient while ice powered cars are around 33%.

                  If you power you EV off a fossil fuel power plant, then that difference, minus the grid losses, the charging losses and then the inverter and motor losses, is how much co2 emissions you are saving.

                  Of course that’s assuming your driving habits don’t change, with that high upfront investment and relatively lower per mile costs compared to using gasoline.

                  And that’s not to mention the one time emission from the production of that EV amortised on its 15 year hoped-for lifetime.

                  Beside capturing government subsidies and the arbitrage saving from using temporarily cheaper electricity as fuel, I don’t see EVs making much sense either from an economic or a saving the planet standpoint.

                  Without a zero emission energy production as the source, EVs don’t make sense beyond hype and cope.

                  All fossil fuel electrical generation, and that includes natural gas, has to be shutdown. Or else it will not make a lick of difference.
