Why are they all from China? Why are they able to replicate so much faster than US labs?
Everyone with half a brain in the US is working the ad-tech and data-mining industries, that's where the money is.

A room-temperature superconductor? New developments

But fear the news if it is discovered that LK-99 increases AI performance.
I'm sure Elon also has SpaceX or something trying to replicate it as well. He sort of has to jump on each new trend anyhow. In a serious note, superconductors are likely useful in electric magnetic motors and probably in high power electronics and batteries in general, no?
I put 1k USD into Tesla today with the same reasoning. Hopefully I don't end up a fool!

#183I haven’t been this excited since the EmDrive
Does LK-99 defy the laws of physics like the EmDrive did?
Re: A room-temperature superconductor? New developments
#184Mostly, I am just glad that all the LK-99 posts are drowning out the "AI" news for a few days.
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…
Superconducting material discovered right around the time conversations about UFOs are kicking off again - coincidence?

Think your EV is so efficient that you only need to charge it once every 5000 miles.
How does a superconductor help with that? Lithium ion is already 95-99% efficient, same with motors. It would help with the charging cable, but that's not increasing the battery capacity. Off the top of my head the main advantage here seems to be MRIs, maybe also maglev trains, maybe generators? It really depends on the form factor of this superconductor compared to copper wire.
Zero loss of energy to heat in any of the conductors. You're not making the battery more efficient, you're making everything else more efficient.

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…
They are also very good energy storage media. Combine that with zero transmission losses - you can now highly efficient EV powertrains that are significantly more compact. 1000 mile EVs become actually viable. Secondly, superconductors are one of the most promising platforms for qubits. Big boost for quantum computing - and these are just two applications off the top off my head.
Except the energy is stored in the magnetic field. Superconductivity or not, you don't carry tesla-scale electromagnets around without becoming a target for high-velocity metallic projectiles and wreaking havoc with every electronic device in the neighborhood. Storage facilities for regulating grid power fluctuations are probably a much more realistic use case.

#187If it's real, how fast could we see concrete applications using this material? 5-year time frame? 10-year time frame? More?
> if you could grow a good single crystal of LK-99, it seems as if the superconductivity might only occur along one crystal axis: put crudely, you'd see superconductivity if you hooked your wires to two particular opposite faces of said crystal, but not to the others! Crystalline grain boundaries are already known to be a big deal in the efficiency of existing superconducting materials, and this would mean that polycrystalline samples of LK-99 would be pretty unfavorable to demonstrating robust effects.
I think this means production of usable superconducting masses will be tricky, if its even possible.
So... Probably on the longer side? Time will be needed to figure out how to make it macroscopically, or discover a similar compound thats easier to produce in bulk.
But once wire, coils, high purity samples and such start getting sold, I think the adoption would be very quick.

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
> for having RTRPS tech flying around for decades
RTRPS = Real Time Role Playing Strategy?

I have seen three now from China alone. Plus a calculation from some respected institute from today that confirms the theory
Throughout this whole saga I've had this feeling that at the very least we can rely on China to really pursue this new development to it's logical end. It's kind of sad, but I don't think I can say the same about the US at this moment. You know for a fact China's going to JUMP on this, figure out if it works or not, and iterate.
I don't get the "disappointment" with USA scientists in this thread not having yet published a replication. There has only been one weekday since the LK-99 revelation came to light. Have some patience.
The analysis from this article is a publication from Berkeley National Lab that has already come out, and Argonne National Lab has announced they have synthesized the material as of yesterday and will release results from their replication attempt in the next few days.

They have a lot of labs, and materials sourcing is easier for them. That’s partially because China is the origin of lots of stuff, and partly because the US regulated red phosphorus as a meth precursor.
Well at least the regulations have worked to solve the meth crisis.
