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)…

4) Mining of a complete mental model of the human mind from collected data. Allows for hacking and social engineering as never seen before.

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

Search on that site for "room-temperature superconductor," and you'll see why it never gained attention.

This is the first time in years where I physically have goosebumps the more this seems to be verified. In a good way. The potential changes this can introduce is equivalent to when Faraday, Volte, and all the other 17th/18th century scientists started figuring out how electricity works. They had no idea how much it would change every aspect of life in the century to come after them.

There is a reason why room temperature (ambient pressure) superconductors have been one of the holy grails of physics for such a long time: the implications are profound.

I used to be a particle physicist, and some of the more complex systems were just those used to cool the superconducting magnets down to cold enough that they become superconducting. If you can do that at ambient temp, you don't have to bother with that entire system.

Also: fusion reactors rely on superconducting magnets (or if you are JET live with the fact that you can only run your magnets for a few seconds before the overheat), so can have a large impact on future fusion reactors.

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.

Fall of the Berlin Wall should probably be on a list of black swan but good events.

That’s my first thought as well.

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...

If it pans out I'd rather they become billionaires than your average tech bro.

Hey Jacques, It's been fun watching your comments on this, you're very knowledgable. :) I had a question, I see some "we made a totally perfect/pure LK-99 it didn't work" - is pure/perfect what they should be going for, to me perfect/pure != correct, however I knew literally nothing about this subject till this week so I have no idea what I'm talking about. Thank you.

I really couldn't tell you what they should be doing, but I'd love for the original samples to be tested by another lab. That seems to me the easiest way to verify the original claims and reduces the uncertainty introduced by the lack of good process documentation and the chance that even the original researches do not quite know how they did what they did, assuming it is all true. The fact that that hasn't happened yet is the biggest source of my continued skepticism, at the same time my optimism is powered by the partial results of the other labs. It's a very strange combination of data, not unlike other things in the past that did not pan out but only time will tell which way it will all resolve.

It’s difficult to rule out external factors - a badly attached probe could also result in zero resistance for example. Showing diamagnetism is one of the least error-prone ways to demonstrate the superconductor effect. That’s my understanding anyway.

That's right. The standard way to measure resistance without being sensitive to contact resistance is called the four-terminal method, see ( https://en.m.wikipedia.org/wiki/Four-terminal_sensing ). You drive a current using two outer wires, but then detect the voltage across the sample using a different pair of wires. You'll measure zero voltage if it's superconducting, since V=IR. Or if one of the probe wires became…

Don’t you also measure the current of the “inner probes” (the ones “driving a current”), to verify that you do have contact?!

> Commercially viable fusion energy. Will change a lot of things Considering that we already have a fusion reactor in the skies, I think that the room temp room pressure superconductor is the next best thing. Fusion is good but at this stage, the natural one will just do. Think global network of solar cells interconnected with LK-99.

Yeah. Perhaps add in some cheap battery technology to the mix of solar power and superconductor, and energy production could become co2 neutral.

The creation of a global electricity network perhaps also has some effect on global cooperation.

Now we just need reduce the use of fossil fuels (cars, aviation, heating, industry).

Exactly, the 99 stands for 1999, so potentially this material has existed for over 20 years and we could have started testing and replication on a much wider scale a decade ago. What benefit have we gained by disseminating this research so slowly?

Neither of them were doing research for the bulk of the time. We can only guess what brought them back to the project, but it may have restarted sometime around 2016.

They can still recover from this reputationally very easily assuming egos are not in the way.

Accept it happened and make amends and make those things very public and move forward to making an official announcement together with the so called 'rogue' author (in my opinion he did the world a favour).
