There's apparently a patent published in 2020. It surprises me that it never gained attention. edit: KR20210062550A - Mehtod of manufacturing ceramic composite with low resistance including superconductors and the composite thereof - https://patents.google.com/patent/KR20210062550A/en

Imagine if human progress had taken a wrong turn in 2020 all becomes of a typo

... all because of ... ?

For 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)…

Sorry to piss on your sunny parade, but:

>> 1) Fully decoding the cellular mechanism of cells allowing for the curing of any disease, repairing any genetic disorder.

-- so you want to cure aging then- how many billions of people you think can a planet with a 6k km radius sustain ?

You think Claus Schwabs of the world wont buy it out to keep it to themselves ?

>> 2) Commercially viable fusion energy. Will change a lot of things.

-- That will eventually happen, and electricity will be just as "expensive" as it is now, simply because the price of a product has nothing to do with its cost and everything to do with the purchasing power of its intended audience.

>> 3) An AI subsystem with some reasoning ability (yeah, could go either way)

-- No, its cant go either way, the power insatiable psychopaths in power will use it to maximize their power. Period. Its psychopath nature- for them its natural and perfectly normal. Until psychopathy is recognized as a disease and sick people are disallowed from positions of power, the world will continue to be an abusive place.

I get the idea of superconductivity at room temperature in theory. But I don't have enough knowledge to understand in real terms, how will the world change if this is true?

Everyone talking about all sorts of important applications. All i want is a maglev hot wheels track using flux pinning. Just imagine all the cool toys a room temp semiconductor would enable.

Breaking the sound barrier in your five-year-old’s bedroom seems like a dodgy business idea.

It would have been more convincing if you had given real past examples rather than speculative future ones :) Although I'm pretty sure there are plenty that many people can think of, so it doesn't really detract much from your point.

Rockets landing themselves back on Earth was looked at as really weird for quite a while.

Here is a good thread on what could be realized if we had room temperature superconducting materials at our hands: https://twitter.com/alexkaplan0/status/1684044616528453633

Twitter (or X or Y or whatever the heck they're calling it nowadays) doesn't show replies if you're not signed in, which breaks all tweet threads. Amazing hostile UX right there.

Basically useless link for anyone without login.

> Why are't more labs outside China making LK-99 and publish videos? 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.

> 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. Implying that Chinese science is bad? Chinese universities absolutely dominate in chemistry: https://www.nature.com/nature-index/institution-outputs/gene... By my count, 18/20 top universities for chemistry researc…

I think for a lot of people this whole saga is probably the first time that they realize that a ton of original work is done in Asia, rather than that it is just our manufacturing hub. They have to adjust their mental model to account for a view of Asia that is in important ways outstripping the West in terms of resources and combined brain power. The amount of scientific output in Asia is astounding, and the number of active scientists dwarfs the numbers in the West. If they would switch to stop publishing in English it would be quite amusing.

So 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…

> Why are't more labs outside China making LK-99 and publish videos? 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.

'Excuse me sir, would you like to buy a kilo of red phosphorous?'

Watch the Connections series.

For those who have not seen it: it's old but it's one of the best productions on the Evolution of science and technology ever made.

Ever see the video of a guy walking past a Saturn V (lying in it's side), doing a piece to camera and pointing to the rocket behind him?

'Connections' (1978). https://www.youtube.com/watch?v=2WoDQBhJCVQ

Off-topic but I'd have expected someone to spell-check a patent title. Mehtod seems like a misspelling?

Spelling doesn't impact the legal weight of a patent, but can help prevent people searching for them. You'd think to put your deliberate typos in the word 'supercobductor' though...

> supercobductor

Now I'm imagining a high-velocity corn transfer mechanism
