Mostly, I am just glad that all the LK-99 posts are drowning out the "AI" news for a few days.
But fear the news if it is discovered that LK-99 increases AI performance.

#42I want to believe
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.

#44I still have a very, very hard time understanding what all of this means. Is there an easy to understand explanation for a room temperature superconductor?
I'm not expert, but I think about it like this: Resistance is the tendency of a material to convert electrical energy into heat. Higher resistance means more of the electrical energy is converted to heat per "time". A superconductor then has the cool property of being able to carry electrical energy without converting any of it into heat. That's obviously cool for energy transmission, but it also enabled some other counterintuitive effects.
Magnetic fields moving through conductors induce electrical energy in the conductors. Normally this is quickly dissipated as heat, but in a superconductor this energy can't go anywhere, and the conductor therefore can't move through the magnetic field.
We've already done a lot of experiments with superconductors, since we've found some that work at extreme cold, but room temperature superconductors would allow us to productive some of those cool ideas by making them economically viable.

#45With all the recent “the government has alien spacecraft news” and the bizarre circumstances of this material’s creation, the (I know to be ridiculous) conspiratorial part of my mind is going “I guess climate change is finally forcing them to take stuff out of the extraterrestrial vaults.”

Can't tell if it's a troll by having a video clip of a video clip
here's the original video, i assume the twitter user didn't know how to download or deeplink to it so they screen recorded it.

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.

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?
