Cold fusion all over again. All the internet predictions of what this will bring are kinda cringey and pathetic

#122So far lab replication efforts are: Two from HUST: https://www.bilibili.com/video/BV14p4y1V7kS/ https://www.bilibili.com/video/BV13k4y1G7i1/ One by USTC https://www.bilibili.com/video/BV1Ex4y1X7ix/ this tiny sample can stand on its pointy side. One by Qufu Normal University https://www.zhihu.com/zvideo/1669820225079070720 One with THU background but claims a personal project https://www.bilibili.com/video/BV14z4y1s7V…
Because all of these replications aren't contributing much; they're bare bones efforts with little to no scientific insight. Not one of these papers is conclusive in terms of showing evidence for it being a superconductor. None of them even contribute meaningfully.
This happens in machine learning all the time. Low quality papers rush in after every major release and announcement in order to be first. But in the long term they're meaningless because it takes time to do a good job.
Good labs don't want to announce half done maybe results. They want to announce conclusive comprehensive high quality results they can stand behind. That's what moves science forward.
Plenty of labs are working on lk-99, but they won't publish this sort of half assed analysis.

I'm sure it depends on jurisdiction, but in the US, you can't patent a material, only a method to make it. If I recall correctly, their patent for method covered a wide range of constituent elements, but left off gold. I would feel pretty bad for them if they genuinely discovered an RTP superconductor but that omission prevents them from becoming billionaires. But more likely the issue is that their current method ha…

If someone else is wrong and you know more, it would be great to share some of what you know so the rest of us can learn. But please don't post unsubstantive putdowns—they just make everything worse.

Good rigorous science takes time to produce. It can take anywhere between several months to a year or more, and the career implications for rushing something out that is later found lacking is not great.

> in the US, you can't patent a material I'm no patent lawyer, but there is literally a US patent-office category covering "material" for exactly this kind of invention. Section 505 - "Superconductor Technology: Apparatus, Material, Process". > This is the generic class for subject matter involving (a) superconductor technology above 30 K and (b) Art collections involving superconductor technology. Apparatus, devices…
I'm assuming "Art collections" means something other than the common meaning, or else that's an oddly specific clause.

I believe there’s no way to stably suspend an object on permanent magnetic fields, so if this is stable and doesn’t fall down then it’s hard to argue superconductivity isn’t involved.
You can stably suspend graphite pencil lead on permanent magnetic fields. E.G.: https://www.youtube.com/watch?v=yeIizmhzPQc
On an array of magnets, but not on a single magnet.

Im posting this reply from my mainstream smartphone: a pocket supercomputer with a 4K 60Hz HDR video camera. I’m chock full of designer vaccines and can watch a catalog of almost all the movies ever made on demand tonight. I listened to an podcast in my EV on the way to work. And SpaceX probably launched 60 satellites this week on the 14th flight of a rocket that flew home afterwards. Things have been moving along. e…
Important correction… the catalog of movies is likely significantly smaller than all the movies ever made… the ongoing removal of new movies for business reasons and the market fragmentation mean that reduced profits are leading to corner cutting with respect to the size of stream catalogs, licenses cost money… pirating via torrents while larger also has diminishing returns as you step outside the mainstream movies,…
I pay a commercial service for pirated content and have access to over 50,000 movies alone. Then there are tens of thousands of tv shows. I can request shows. It gives me access to all major streaming services content. Anything I have ever searched for is there. Shows from around the world and all around feels like unlimited content. Cheaper then Netflix and I definitely feel I am getting great returns for my money. One day we will look up to pirates for saving our culture.

#129For those experiencing this type of "black swan, but good" event for the first time, it is helpful to recognize that the human tendency to believe that all future "big events" will be dystopian downers, is statistically unsound.
For a while I've kept a list of the things that could be "good" swan events, but to be fair I didn't have "room temperature superconductor on that list" :-)
Other things that could happen:
1) Fully decoding the cellular mechanism of cells allowing for the curing of any disease, repairing any genetic disorder.
2) Commercially viable fusion energy. Will change a lot of things.
3) An AI subsystem with some reasoning ability (yeah, could go either way)
Etc.

Red phosphorus, one of the ingredients in the synthesis, is a controlled substance in the US. Might be delaying everyone while they fill out the paperwork with whoever their supplier is.
