People are quick to dismiss astrology, but the last time Pluto entered Aquarius (which will happen for the next 20 years starting in Dec) we had the Industrial Revolution. The time before that we had the Scientific Revolution. Things are right on track with this discovery.
Room temperature, ambient pressure superconductivity – this time for real?

#182The Wikipedia article on LK-99 now references a Korean source claiming that this was submitted to Nature in 2020 but that the paper was rejected.

That's extremely hilarious if real. He basically just told the guys at the Max Plank institute they're lazy theoreticians that don't understand chemistry and can't be bothered to put in the work like he has. (over 100 attempts at making this!)

Correlation is not causation. Why would the position of the planets have anything to do with the discovery of revolutionary technology?

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.
Yes, I think sensors are the big potential application. Some motors are already 95%+ efficient, so 99% would hardly be a revolution, though reduced cooling would be a benefit.
Actually, going from 96-98% to 99% is still huge. Assume the lower efficiency motor is 100W. You waste 2-4. Presumably you can dissipate that amount of heat.
Now, the same form factor can do 200-400W and be ok.
So it doesn't change the efficiency of the system (we still use a bunch of wh) but it dramatically changes the form factor of the motor!

#187Interesting thread, looks like a lot of labs are on the charge to replicate this https://twitter.com/alexkaplan0/status/1684554551481835520?s...

I'm following this fellow: https://twitter.com/andrewmccalip Seems to have the right energy [edit thanks folks] https://nitter.net/i/status/1684433849781202944 Here’s a more colorful play by play as well: https://nitter.net/8teapi/status/1684586672917565443
I love the colorful play-by-play. It could almost be a kdrama. It's also kind of crazy that one of the authors did over 1000 experiments until he found LK-99, regardless of whether it checks out. Talk about a grind mindset.
Material science can be like that … you’re pretty sure your theory works and your results don’t wildly invalidate it, but they aren’t good enough or are missing a property or something… and it turns out you could very easily have made a bad batch, poorly aligned fibers, badly mixed epoxy, or any number of possible issues… so you try again and again to get it right… sometimes it’s for very little incremental progress in state of the art… other times it might be a Nobel prize winning superconductor.

#189If this confirms, I really hope that the current limitation can be overcome. That would be brutal to actually find a ambient temperature and pressure SC only to have its usefulness for big real world applications be nerfed.
If it's confirmed, people will be investigating improving the process for manufacturing LK-99 almost immediately and have some success, as well as looking into similar materials with different doping etc. It's likely that there would be at least some that also exhibit RTP superconductivity, though it's also likely they would share many of LK-99's weaknesses. Though that's all getting ahead of ourselves...

Asking the AI in my pocket what the new superconductor technology can do for society. We’re kinda in the future, and that’s neat.
With apologies for being the pedantic person, you're not really asking the AI in your pocket. You're just using the web browser on your pocket computer to compose a message to the massive AI system running in some datacenter somewhere. Ironically, if this problem does get solved, you could have the whole AI system in your pocket.
That’s implementation details, in my opinion. I reach into my pocket and talk to AI.
