I 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?
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…

Because I'm a "Very Busy Person" and don't actually have all day to screw around with "every YouTube video", I come to HN to optimize my time spend/information gained ratio.
Likewise, on this topic, even the above is still confusing. People say it's more efficient, then replies say we're already at 95-99% efficiency so it doesn't matter much. I'm still fairly confused!

#133Mostly, I am just glad that all the LK-99 posts are drowning out the "AI" news for a few days.
Get tired of one set of assholes? Funnel resources to another set of assholes (who also wish you harm).
If this turns out to be actually true then everyone will want to talk about fusion again. I don't know if I have the stomach for it. But as you say, at least it's not AI.

Anything is better than crypto.

AI is useful enough to be dangerous in the hands of bad actors, where the marks are not just the suckers but the people who want to have nothing to do with it.

#137With 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.”

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

[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.
