I don’t understand how superconductors will make phones into supercomputers. There is a still the limitation of the number of transistors in a given volume. Also, how does this help fusion become possible?

Currently transistors and connections use a lot of power just to transfer some bits, superconducting wires and maybe transistors would help. > Also, how does this help fusion become possible? Stronger magnets which you don't need to cool with liquid helium will help achieve better plasma confinement.

That’s really interesting. It seems like this technology could be huge

Maglev trains, fusion power plants, fanless super computers in your pocket that charge in a minute and don't get hot. Basically utopia.

Superconductors can make very powerfull lossless conductors, and therefore powerfull magnetic fields. Which is great if you need to contain a fusion reaction. Also not needing to cool one side to near 0k and the hot side to millions of degrees helps viability of fusion.

Processors basacally convert almost all power into heat by resistive losses. With room temparature superconductors you'll only consume energy on the state changes of the processor.

With this superconductive material you could create loops of wire (like a resistor) but instead it would store energy practically lossless in a few seconds.

Superconductivity up to 100c and 1bar would be a historic moment in human ingenuity.

Anonymous or not, the "MPI guy" explains why he came to this conclusion, and it sounds legit.

I feel like you anonymously and uncredibly (no offense intended) saying "sounds legit" kind of ignores the problem being pointed out here...

"this may spark a revolution in electronics as significant as the invention of the transistor, vacuum tube, and induction motor." How, exactly?

Shareholders and CEOs increase their wealth.

I don't think we need new technology for that.

The interconnects would have better loss functions. We'd be able to crank up the frequency to processor levels.

Just for fun: Am I the only one who thinks there's connection between this and the UAP news that's coming out? RTSC would probably enable a lot of incredible energy & maneuverability capabilities... Sorry, indulging in a little off-topic conspiracy theorizing.

It is fun to joke about alien technology. But they are unrelated in reality. In fact they are pretty uncorrelated in terms of timeline. This material has supposedly been waiting in the wings for a while.

> has supposedly been waiting in the wings for a while

I'm not sure if that holds, the tic tac UFO has no actual wings :P

Superconductors are in the name. They're ideal conductors. As a corollary, superconductors coiled into a wire, shaped like an inductor, are also ideal inductors. By ideal, I informally mean nearly perfect in a mathematical sense. A thin superconductor can carry an almost arbitrary amount of electricity with 0% loss. This is a real-world application already for superconductors, but it requires cooling the entire condu…

> an inductor made out of a superconductor, that is looped back on itself, can hold a magnetic field indefinitely, with 0% loss. Energy storage. In a way that could be used to power a car?

I'm afraid not, the magnetic field might be a bit too strong.

But for local/grid storage, it's perfect. Also, infinite magnets, this might allow for less neodymium in renewable. And probably dozen new applications we don't think of yet.

I said 3 years ago on this website that the only techno silver bullet I believed in against climate change was room-temperature superconductors, as this would help tremendously on

- interconnections,

- energy storage,

- efficiency,

And obviously help with plasma research, that would then help with both fusion and space catapult.

I was disappointed way too much by tech news in the last 10 years, but if this is true, I'd be really happy.

What if the team itself did create LK-99 that is a superconductor, but they aren't able to reproduce it and only have the sample left that works. Hence, they aren't able to make more of it to prove their success, but rather decided to release the paper and method so that others can try to reproduce it. Given the amount of interest, they could put hundreds of labs to work trying to recreate what they themselves can't,…

I think it's unlikely in this case. They seem to have gone out of their way to show a method that can achieve replication using very common materials and pretty much medieval-grade technology (except for the vacuum pump, maybe).

Ok, if that's the case, why the imperfect demonstration? Why not dozens and dozens of videos showing such a monumental success in action? The lack of clear evidence, especially with social media frenzies, is a red flag in my opinion.

Small. Imperfect contact, unplugged terminals, etc. These are not 1st year grad students who don't know what they are doing. The authors have decades of research and fabrication experience, and publications to back it up. Comments that insinuate it could be those kind of novice mistakes (other comments on HN/reddit, not yours) are frankly insulting and speaks to a profound arrogance in being unable to accept a new di…

I apologize if I came across as insinuating it was an error, I was just asking you for your assessment of the chances it could be an error. I'm not well versed in the subtleties of physics experiment measurement, so I figured I'd ask. It's difficult for a layperson to determine which "side" is right when battle lines are drawn after these types of announcements.

I know, I did not think for a moment that you were making such an accusation. I was referring to the other comments on HN/reddit over the past week making those accusations. Sorry if my comment came off that way.

My German is poor. Does this say: Q: The layout is very shitty! A: No, it’s the historically default layout.

"Jo" is "yupp"

Thanks! I've casually studied German, but I'd never come across "Jo".

"Jo" kind of reminds me of Dutch vs. German, where many corresponding words are just slightly different.
