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,…

So basically 'more efficient'? I'd dispute the 'dramatically' more efficient power grids, unless that's couched in industry terms - ie a 10% reduction in transmission losses might be 'dramatic' for energy grid engineers. But not really world-changing, for the rest of us. "Aerospace and Defense: Superconductors could be used in a variety of aerospace and defense applications, such as advanced radar systems, satellite…
SQUID sensors would be very feasible, with increased sensitivity. I just learned that extremely directional transceivers would be possible due to some weird quantum effects. Probably propulsion would be affected by higher efficiency motors. So it's a huge deal if it's real.
Some motors are already 95%+ efficient, so 99% would hardly be a revolution, though reduced cooling would be a benefit.

Conduct electricity with zero resistance. This has been possible at cryogenic temperatures (powers supermagnets, MRI etc) but running at room temperature _and pressure_ means in theory that you don’t need expensive support machinery. Has been the holy grail for the field. If true, this specific case is only low current, but demonstrates such a thing is possible - almost certainly winning an instant Nobel Prize.
Does this mean there would be no heat waste? And devices like phones and computers wouldn't get hot?

What would the internet have gotten "wrong"? It's a paper and now people will try to replicate it. Some informed people give their take on why it sounds right and/or wrong, but ultimately they aren't (and can't) verify or debunk it yet pending further investigations. I have zero expertise to give an opinion either way, and honestly the impact of room temperature/pressure superconductors just doesn't seem that overwhe…
This story deserves no more attention than the 10,000 crank papers submitted to Arxiv every day about time travel, prime numbers, antigravity. There is nothing worth replicating. That's what they got wrong.
Can someone explain why this is a big deal? The author cites that it doesn't need an explanation, but I definitely need one lol.

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

Stronger magnets which you don't need to cool with liquid helium will help achieve better plasma confinement.

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.

Except one of the authors on the good paper is a professor at a legit research university with thousands of citations.
