content: Has a Korean quantum research group cracked the holy grail of physics, an ambient temperature and pressure superconductor that will win them a Nobel prize and change humanity forever?Probably not.Dave completely busts the demo video of their LK-99 material with a pracical lab example, it's so embarrassing you won't believe it!Links:https://qcentre.co.kr/https://arxiv.org/abs/2307.12008Paper 1:https://arxiv.org/ftp/arxiv/papers/2307/2307.12008.pdfPaper 2:https://arxiv.org/ftp/arxiv/papers/2307/2307.12037.pdf00:00 - This LK-99 ambient temperature & pressure superconductor is going to CHANGE THE WORLD!02:52 - Low but not zero resistance? I thought this was a superconductor?04:22 - Some journalists are actually doing their job this time06:28 - The Meissner effect07:11- Thunderf00t's take08:06 - This demo video is just a total embarrassment! It's just Lenz's Law!10:36 - Let's reproduce the experiment!

content: The whole thing has been poorly handled. From the papers full of errors, the videos that don't prove anything, the questionable graphs and even more questionable results. I'm not an expert so I'm just reading the forums of what I assume are experts. They are not impressed. I hope they're wrong but I don't think they are.

I can create a youtube channel in minutes, I can upload a copy of the video and to put in description whatever I likeI want to see a prove that youtube channel is owned by the quantum energy research centre - otherwise the copper demo means nothing

content: Yes, even if it could work, it likely would be limited in capacity, and would, if you can make small ceramic units, make for great bearings for small fans, like PC fans, with a life and RPM an order of magnitude over regular ones. Get the noise ultrasonic, and the life over 100k hours, and you can have non noisy fans, or at least ones that are easy to silence.

content: Remains to be seen.I can't blame everyone for being skeptical though.If it ever does turn out to be true, even though it's a ceramic, it could revolutionize a lot of things. Ceramics can be formed into small coils or be used as conductors embedded into substrates for various integrated and/or hybrid circuitry or deposited onto circuit boards as traces.Once you have a magic wand you begin to find all sorts of things to wave it at.

content: Quote from: EEVblog on July 28, 2023, 01:23:52 amLooking at the photo in the video above:I can say 2 things...1. I used to play with pennies on speaker magnets when I was young and I could occasionally get 1 or 2 coins to slightly stand at an angle if placed down and oriented 2 to 3 pennies just right. If this material isn't evenly magnetically distributed across it's surface, this effect could be a fluke.2. I've seen examples of diamagnetic materials, the effect shown is a little too strong for the run of the mil diamagnetic materials, if it wasn't for their other super blunder video, I might be forced to say they may have the beginning of something, but don't have a clue as to the required refinement component which makes it work or how to replicate. Basically what you see here is the sole semi-functional sample in existence and they have yet to replicate anything larger than what you see.

It's a pointless video. It doesn't indicate anything one way or the other. There's no particular text explaining what the video is about, other than saying it is a "Magnetic Property Test of LK-99 Film".I wonder how many more posts we will see here about this video before we find something useful reported re conformation or refutation of the paper?

This is the kind of level of silliness you expect from a dodgy crowd funding video, let alone out of a university studying this stuff.You put up a stupid video *front and centre* on your *commercial* website and bask in the worldwide glory of this discovery, damn right you are going to get called out for your stupid ridiculous video.Play stupid games, win stupid prizes.

Complaining about this video is no different than complaining about news reports and how they are distorted by the reporters. This video might well have been posted because of marketeers at the organization. The people directly connected to the project might well know nothing about it and have no authority to have it removed.I'm waiting for more substantial news, from the researchers, both in this company, and the others who might duplicate the research.

That's my point and you are proving me right.We have reached the point in the conversation, where each of us has made our points very clearly. You wish to be a drama queen about this. I prefer to acknowledge that there was a scientific paper written, and wait for the scientific responses. Anything else seems to be hype.Until there is something worth responding to, I won't bother you further.

Am I not allowed to do that? Why?That video was probably the most ridiculous thing I've ever done a debunking video on.If you can't seperate debunking that video from the actual research and paper, then that's a you problem.QuoteWatch my video again. You clearly MISSED the part where I said that there could be something to this and that teams are working on trying to reproduce it. Great, wait for the results. That doesn't mean people should not mock that ridiculous video. It's a complete embarressment for the entire scientific team.QuoteYou won't be missed, LOL.

content: They changed the video description!It's no longer a copper plate, it's an enriched uranium 235 plate!And they somehow reset the video view count and thumbs without changing the URL.I'm no chemist, but it's a very strange material choice to demonstrate your superconductor film. And it's one of the most controlled materials on earth, so the cynic in me says it's very convenient if you don't want people to verify.I can't help but think they are just taking the piss in response to my video.In that case it's rather funny and I tip my tap to the joke. But when the whole world is questioning the credibility of your research, is that such a good idea?But I'm open to someone explaining why you'd use enriched uranium 235 for such a thing?

content: EDIT: I see Ranayna already posted this above. I should have twigged to this when the video count had been reset.It gets stranger. There are two videos, they didn't change the description.The link I posted is the one I had in my video description and card. But I checked my actual video and it is indeed the other video (that still says copper) with 179k views.So it seems there are two copies of the videos on two different channels. Once channel is "@qcentre" and the other is "@q-centre". Both have legit emails to the company domain, and the uranium one is on a channel dating from 2012 but was uploaded yesterday.I don't know how I got the newer video link in my original video description and card, but used the original one to record the screen capture.So more evidence it's a joke re-upload? But if so I don't know how you fake the business email address, so it's got to be them.The "copper" video:The "uranium" video:

Who knows.https://qcentre.co.kr/is still down for me, still with what deeple translates to a "Bandwith Exceeded" message, so i do not know if they are reallt now linking to the "uranium" version.

I don't think it was ever supposed to be released.That information seems to make sense. Someone made this material, worked on it, then left the research. probably realized his idea will never work. Then someone else picked up the pieces, saw that he was working on room temperature superconductor, and then it got released somehow. I mean, if it work, that's instant Nobel price, and investments until the cows come home.
