I didn't think you meant the latter bit literally but the former bit was isomorphic to $frequent-misperception so I figured I'd better respond in kind!
Thank you.

Sounds like you've got a very interesting weekend project coming up!
The synthesis section honestly looks very simple, I would assume a simple ceramic kiln could be used? You just need PbO, PbSO4, Cu, and P powders.
P powders are tightly regulated in the States, but alas,that's where I live. How many matchbooks does one need to purchase to replicate this study?
Re: The first room-temperature ambient-pressure superconductor?
#893Based on the paper, results, video etc., this is either legit, or a massive fraud. I guess we will know soon enough. If it is real though, this is a massive step up for humanity. The stuff of science fiction.
Or misread calculations?

That won't save us. Not unless you know how to build it in the next 5 years. https://news.ycombinator.com/item?id=36836722
Even if you were right, it behooves us to act as if our actions mattered. Otherwise, what’s the point. I don’t think you’re right, for the record.
You're right. But, we should also do things that matter. This wouldn't. Right now, our horizon is literally 5 years. Anything that doesn't help in the next 5 years needs to get in line, because we've got 50 years of inaction to make up for.
OTOH, I am also not sure what we as a species can do in the next 5 years that actually will matter.

Superconductors have a current limit above which they are no longer superconductors. It is possible that a room temperature superconductor could be created that has a limit too low to be of any practical use. It seems this is worth cautious excitement, but don't get too excited yet.
250mA at 25 Celsius, according to the paper
It stop superconducting at 250ma? It’s useless!

Please explain the benefit of faking the result of this paper and destroying your reputation.

In other words, you agree with my original point.

They've just proven (if true of course) that it's possible at all. That is a massive, massive leap. And once it's possible, it won't be long until it's optimized. We've seen this everywhere -- transistors were once huge and now nanometers; solar cells have improved in every where; batteries are cheaper and better than ever.
I was with you on the first part. If this proves room-temperature/ambient-pressure is possible at all, that is huge. Not so sure about the "won't be long until it's optimized," though. There are a lot of examples where something seems perpetually 20 years away. I'd advise tempering the transistor-based optimism with just a skosh of fusion energy skepticism.
It has 4 fairly common ingredients and only needs a couple of days to create. You can be sure that China will make a spreadsheet with all possible combinations of synthesis and farm them out to their Universities for rapid development... and then they start hunting for the 'ideal' version... flexible, fast to synthesize etc.
The Manhattan project and moon landings happened because the US spent a significant % of it's GDP on the project. We might have Fusion already if they repeated it...
LK-99 is just chemistry... not nearly as complicated.

Believe it or not, the levitation effect can be found in non-superconducting materials with a high diamagnetic constant such as pyrolytic carbon. Induced magnetic fields are created by "effective currents," which can occur in zero-resistance systems that are not called superconductors (because they can't conduct across a significant distance, only around a tiny loop) like molecular or atomic orbitals. https://en.wiki…
Diamagnetism was my first reaction when I saw lead, and the addition of copper makes me think eddy current reactivity.
...and this is Eddy's sofa, is it?
Re: The first room-temperature ambient-pressure superconductor?
#899the patent application is here https://patents.google.com/patent/WO2023027536A1/en?oq=WO202...
Yeah, nobody get too excited. We still have to wait 20 years for the patent to expire.
Huh? The patent system isn't for people to block anyone from using an invention for 20 years...
It's to protect the inventors while they license the technology.
If this works they'll be licensing the rights to use it to some massive companys... besides multiple Korean companies are already invested in it...
LK-99 would likely only be a first step... a brittle crystal doesn't make a great power line...

You don't see, I don't see, but I believe they saw.
