IANAP, but a layman's understanding: the materials that we have available today to conduct electricity at or around room temperatures largely do so in an inefficient manner. As electricity moves through the material, some energy is wasted in the form of ejected heat. To circumvent this, physicists discovered superconductivity: a state in which a material is a perfectly efficient conductor of electricity. Thus far, to…

"Inefficient" is a rather relative term here, since batteries, motors, and transmission wires are >=95% efficient already.

Is not like we lose 5% of the stuff and that's it.

We lose it to HEAT and that has a lot of limitations like the stuff melting and exploding.

It's a conductor of electricity. But super good at it. i.e. - It has zero resistance to electricity. Currently, the best superconducting materials we can create have to be chilled to near absolute zero, which means designing them to work in liquid helium baths. This is expensive, and difficult. If a material can superconduct at room temperature, now we're talking usage in general purpose consumer goods. As for why we…

Would a room-temp superconductor make it feasible to cover desert regions with solar panels and transport the electricity long distances?

Yes it makes it more feasible. But even with superconductors, you still need to build out the long-distance grids. With ceramics, manufacturing that much powerline might be the challenge. With the maximum current density reported for this material, you might need a huge x-sectional area.

You still have to worry about batteries. Unless if you place equal numbers of panels separated by 120° meridians for example.

And then there is coordination between governments. This is probably where such an initiative might fail.

AI has already taken over the internet and is just feeding us news stories based on what it already knows. Super conductor discovered by a team who's been searching for 20 years. Internal conflict 'proves' there's something to argue over. Low quality, confusing information that's hard to decipher, but kind of makes sense. Asian language information streams and videos. Musk buys twitter. A submarine visited the titani…

If you want a tinfoil hat, consider that the LK-99 news dropped around the time that the US military is being exposed for having RTRPS tech flying around for decades

"RTRPS tech" doesn't turn up anything on Google. What does this even mean?

Anything is better than crypto.

How about LK-99 coins!?!? Right? Maybe we use diffusion to design them so they are "super-conducting crypto AI coins" get yours now for only $199 at the Philadelphia Mint. Act now, supplies are limited!

I'm going to use my new skills as a Prompt Engineer to get Stable Diffusion to produce some NFTs for me, and use the profits to invest in a SPAC targeting LK-99 start-ups.

Now explain that sentence to a caveman - or even to someone in 1990.

And a great many people also want you to believe. Just remember: don't give anyone any money, not until this is properly verified.

Who could you possibly give money for this? It's not like there's a as-seen-on-TV ad for superconductors. But I agree that it needs a healthy dose of skepticism until several reputable groups have replicated it.

Well, not with that attitude.

I have seen three now from China alone. Plus a calculation from some respected institute from today that confirms the theory

Why are they all from China? Why are they able to replicate so much faster than US labs?

Argonne doesn't need to make a name for itself, they already are a "global brand" in science.

They won't jump to publish a video on social media of the first replication of diamagnetism that they get. They'll be putting together a definitive and defensible paper on the production and properties of the material. That will take longer.

And if they can't replicate it, then it'll drag on longer without hearing anything from them, since they'll have to try multiple different methods and reach out to the authors, and iterate until they've exhausted enough possibilities that they feel confident enough publishing a failure to replicate.

Mostly, I am just glad that all the LK-99 posts are drowning out the "AI" news for a few days.

The only thing I care about is voyager 2 and I'm not going to hear how that thing is doing until October 15.

[not an expert but...]It shows strong diamagnetism(being repelled by both of the poles of a magnet), which is a property of superconductors. Not necessarily a superconductor though, that’s still to be established but at least it shows that the inventors are up to something and it’s not complete fabrication.

Why don’t they try heating it and seeing if the effect goes away? You could even try a welding torch or something.

Not only is it a purported to be a room temperature super conductor, it's a relatively high temperature superconductor, not guarantee the effect goes away if you put it under a torch.
