It is still too early to celebrate, but this would be such a huge deal, holy fuck.

    The funniest time for us to develop room temperature semiconductors is right after a huge boom of filling warehouses with bitcoin gpus, so this could actually be happening

    The 2 "replications" as of now are just of some somewhat clear "floating" but no clear confirmation of the meissner effect or flux pinning taking place (superconductor specific mumbo jumbo) , or conductivity measurements. To be clear it is positive but not proof of superconductivity, its consistent still with a few other very niche magnetic property combinations. Maybe it is some weird super diamagnetic material but that kind of stuff isnt really well understood or modeled either. But it seems like it wont take too long till we know what is happening actualy. Like in a weak

    seems like the korean team that has been working on it for years naturaly had a better sample and more trial and error and prob a lot of the unclear behavior in these first few tries is because naturaly the quality of the samples or the structure is all over the place. Most attempts failed either way. For a non standardized process some teams may gotten luckier and got a semi working flake of the material. From the paper the lattice position that the Cu atoms need to replace the Pb ones for the structure to deform/symmetry to break in the right way for the assumed properties to arise is the less favorable energy wise of the 2 the Pb occupies. So its likely that in the "successfull" replications portions of the flakes got the correct structure so you end up with some localizd superconducting ereas and other ereas of other magnetic behavior. Thats an optimistic scenario where the thing is indeed a room temp superconductor

    Looking forward to getting a levitating desk trinket once china optimizes the synthesis/manufacture of this stuff.

    I also think there's been a paper that explains what mechanism could be causing LK99 to be superconductive (if it ends up being confirmed)

        The replications and the paper are def. interesting. I put my first guess into the similar reign that this video does, though: https://www.youtube.com/watch?v=RjzL9cS3VW8

        It is sceptical.

    Once again, wake me up once it actually does something practical. In real life. Not a lab.

    We've been superconducting cold fusion perpetual motion machines on the 10th planet since I was a kid. And I am extremely old.

      I get not wanting to get too hyped, but this is a weird take imo. This isn't near the same in-feasibility as cold fusion or perpetual motion machines. Everything starts in a lab, if this ends up being real it doesn't need to be super useful, it gives us a place to start actually looking to find stuff that does work for us.

        "Big breakthrough" stories are a dime a dozen and 99 percent bullshit to secure more funding. Can't really be mad at them for being skeptical.

          are they really? most of what you're talking about is the media over-hyping papers from scientists, but this paper would actually deserve the hype if it's true. And this would be such a dumbass way to secure more funding, this would ruin your reputation if you had to retract. It's not being skeptical that I'm "mad at", it's the comparison to cold fusion and perpetual motion and a 10th planet. This is more in the realm of "we got fusion to give us net positive energy input" level tech

            It’s more than that really. Net positive fusion reactions have been done. Making an actual, usable reactor is another thing entirely. There’s a ton of things to still work out.

            This would be way more of a huge impact, very quickly. Even if this particular compound ends up being non-viable in an industry sense, it would be a paradigm changing discovery. It’s a thing with inherent value, and that doesn’t need huge amounts of new engineering solutions to come with it to be useful, unlike fusion. If it’s a room temperature, normal pressure, superconductor, and you can make half-decent wires out of it, the world is changed.

              my understanding is that we still spend way too much energy in like containing the reaction, I was aware we had managed to get more energy out of the specific fusion part (idk how to word what I'm trying to say). But yes I'm aware of how massive this is, I'm more trying to say I think it's at the same tech difficulty of trying to get fusion to work, not something ridiculous like cold fusion

                Well, there has been net energy created, in the sense that a reaction was made that generated more energy than the apparatus driving it used.

                Just, doing this is hell on the machinery it’s done on, so it’s not really a viable power source yet. There’s a bunch of engineering problems to solve first.

                  yes, like we got more energy from what we actually used to ignite the fusion process, but we use a ton of energy to actually be able to keep the reactor running is what I'm saying (like all the shielding and shit)

            I was coming at it from a media perspective. There is a reason nobody takes this crap seriously.

              but the problem with media isn't hyping up cranks, it's hyping up shit when the paper they're hyping doesn't even make any claims close to what the media is saying. This really would be worth the hype like I said

      We've been superconducting cold fusion

      not at temperatures that don't require liquid helium level temperatures

    I hate that my first reaction was that this is probably fake. I'll remain skeptical so I won't be disappointed.

      Same. I remember the electromagnetic engine that supposedly violated conservation of momentum, then turned out to be measurement error. This thing: https://en.wikipedia.org/wiki/EmDrive

      This is way in to "extraordinay claims require extraordinary evidence", healthy and robust skepticism is the correct position. That said, if it works, we all get flying skateboards.

    So what would this mean?

    The Capitalists bullshitting out huge efficiency gains for basically everything, allowing a huge increase in consoom with less environmental damage or something?
