    I would say “High Temperatur Superconductor”. If they can be made cheaply, they solve our Energy Problems in almost every way. Turbines will become more effective, Transport of Energy cheap and lossless and storage crazy effective. They will also revolitionize meassurement of magnetic fields witch will have a huge impact on medicin and other fields.

      Wow, that must be the best answer yet, at least from my ignorant point of view about the feasibility. I am extremely fascinated by material science. Are there any promising lines of research for this?

        Yes. Every now and then we get a paper claiming that they found a HTSC. It always is a big deal because they are considered the holy grail of solid state physics. Later we find that it’s a mistake.

        We are pretty good though. Records are in the area of −135 °C (138K, -211°F) but the phenomenon was thought to be at a few Kelvin max in the last century.

        The big BUT is that it’s science. Meaning that it is not granted that such a material (superconducting at ambient temperature and pressure) even exists

          So the keyword to monitor is “HTSC”, got it. I heard Sabine Hossenfelder comment a few papers, but I have no idea about the full body of research.

      It’s amazing the amount of ressources that are spent on creating an environment/platform that locks users in.

      Like, shit, if we spent like 10% on that efforts into open source stuff we’d be living in a utopia right now or something.

      I’d rather a free and powerful energy source that’ll benefit humanity not have a logo and pricetag slapped on it so that only the ones who can afford it are allowed to use it.

        Any energy source is going to be able to have a price tag and a logo slapped on it as long as energy generation requires infrastructure and capitalism is a thing. Wind, solar, and tidal are great; we desperately need more of them as part of our energy strategy. But they can also have a price tag and a logo. In fact, home solar has become quite a lucrative…well, not exactly scam, but “bad deal” in my area.

        And fusion will have to be here, too, to fill the gaps that wind, solar, and tidal leave; at least for now. There’s no “forever” answer here, only some that’ll last longer than others.

            Indeed. Any company can claim to own anything. The question is whether or not it’s lucrative enough to do so.

            Precisely. It’s already done to our homes and our food and the water we drink, pretty soon it will be done to the air we breath unless we stop that unnamable thing that privatizes wealth and is defined by the ability to profit from it.

    Recycling and right to repair. If we could reclaim ~100% of raw materials in a useful way and avoid unnecessary waste it would have a big climate impact.

      I mean, it’s not like we don’t know how to do that. But selling you a whole new thing every year or two is much more profitable than selling you one thing that lasts you a lifetime.

          My problem with counting all climate change is that the goal itself is not unique: there are atmospheric greenhouse gasses to lower, which are something completely different than the acidification of the oceans, which are completely different from deforestation.

          And the effects themselves are, it’s true, all originated from an imbalance in a system, but exactly because climate is a complex system, they differ wildly.

              I agree. Still it is a set with way fewer elements than action against climate change. Also, the nature of operations in the latter case is way more diversified than in the development of the former.

              It is only my opinion though, you may find Generative AI a hydra compared to the other.

              By the way, the money would be well spent indeed but not even close to enough for a sustainable change.

                also we could just hire a few hitmen

        Buying companies that create a lot of pollution and closing them down. (Coal mines/plants, oil firms, single use plastic suppliers, etc)

        Another big one would be buying up pharma companies an their patents and releasing everything under creative commons license.

          Question on this, how would you expect the millions of people that heat/cool their homes to get by? Or are you advocating for a return to caves ? Unless you’re saying shut those down to build nuclear/solar/wind, which also takes a lot of dirty manufacturing to build. It’s kind of a no-win with this many humans.

            Bio gas is a lot better than coal and fossil oil for the mean time. But long term basically the whole world should be using heatpumps for heating and cooling, they are incredibly efficient and outperform any other system on every metric. Especially because electricity will become dirt cheap in a few years/decades.

            The only reason they arent installed in every house yet is the fossil fuel lobby and their bought politicians, but even they are slowly realizing that its the inevitable solution.

            which also takes a lot of dirty manufacturing to build

            Solar compensates its production+installation footprint in around a year see here for the relevant numbers from the US National Renewable Energy Laboratory

            Wind power plants compensate theirs in a matter of a few months. See this part of Climate Towns latest video analyzing the typical propaganda that made you falsely believe that https://youtu.be/wBC_bug5DIQ?t=185

            Nuclear is obviously stupid and does indeed cost way too much and take way too much effort for how bad of a deal you get out of it when its done.

              I for one would love to live in this world where electricity becomes dirt cheap, as my rates have only ever gone up, usually in the name of installing more renewables, now don’t get me wrong I’m not against installing renewables but let’s not pretend it will necessarily make power cheaper for the end user

                It will. Consumer electricity prices are completely artificially inflated. No matter how corrupt the the system is, eventually the prices will be pushed down because there is such an over abundance of energy output. Already we are seeing exchange prices regularily going into the negative.

                We might ofcourse dump all that excess into garbage like AI training.

    I want a machine that works me out while I sleep. I’m talking full body ripped (to my desired levels) all while I get my sleep for the night.

    Just electrically stimulate my muscles constantly while keeping me in a deep sleep for 8 hours straight please.

    I wanna wake up every morning feeling like I just left the gym after a solid full body work out.
