Notes (DeepL Translate excerpt from article linked) On the recent people hotly debated "if really immediately can get the Nobel Prize 'South Korea room temperature superconducting materials LK-99 paper'", July 28, Nanjing University, professor of physics Wen Haihu interviewed to the surging science and technology, said. "It's really buzzing, but it's not surprising because this thing is important." "Most of the (buzz) people are not doing superconductivity." "We carefully analysed their data, and from three aspects - resistance, School of magnetisation and Physics, China High N/A N/A so-called magnetic ScienceNet.cn Nanjing levitation - none Link University of them are sufficient to show that it is a superconducting phenomenon (material)." "We judge that (its so-called superconductivity) is most likely an illusion." As for repeating the experiment, Wen Haihu said, "In fact, we didn't even want to do it because we judged that it didn't look like superconductivity, and then we also sent one of our classmates to work on it. Many groups internationally are repeating it. With our experience, (the data published in the current paper) is not enough to show that it is superconducting." Click to expand... Click to shrink...

Click to expand... Click to shrink... No. The problem with the hyperloop [at least the revision I am familiar with: there have been a few] Is that it relies on a near-vacuum [or very low pressure, again depending on design] tube to reduce air resistance to allow the fast speed of [S:trains:S] PODS! they use. A very good superconductor doesn't resolve the issues of repairing and maintaining a large-scale network of train size vacuum tubes, or protecting them from catastrophic breaches. Back to the superconductor, from what I've seen posted here, it looks like the material they've made is at least surprisingly magnetic in independent testing, if nothing else? * 18 GrandNord He/Him * Yesterday at 10:04 AM * * #254 Teiresias said: Considering the applications of superconductors to maglev technology, would a room temperature superconductor mean that Musk's hyperloop idea is now much more feasible? Click to expand... Click to shrink... In addition to the vaccum issues stated above, using individual pods (as is the silicon valley's obsession) is just inherently far less efficient than a train. One of the main killer of a transport system's efficiency (besides the speed), is loading and unloading time. With a train, everyone/ everything is loaded and unloaded in one go, with pods, it's one by one, unless you load them all at the same time, make them travel together, and then unload then, but by then it's just a more complicated train. The only upside is that you could decouple and separate some pods without having to stop them all, but it's a complex, potentially error and accident prone solution to a problem that doesn't really exists. Ligth rail and trains are just a superior solution to individual pods. * 39 Doggydog Doggydog Professional Attack Chihuahua * Yesterday at 10:41 AM * * #256 Guys, I'm starting to think it's actually a superconductor.

Click to expand... Click to shrink... No. If anything, it dooms hyperloop even more, as actual Maglev Trains, the largest competitor to the Hyperloop concept (besides planes), are now going to be significantly cheaper to set up. Maybe even a little faster than they were before. The reason why Hyperloop is a stupid idea remains the same: Keeping vacuum in a tube that is thousands of kilometers long is insanely difficult and expensive. Nobody has done such a thing before, or anything even remotely close to that And may in fact not even be feasible at all at current level of technology without the Manhattan Project/Apollo Program level of spending. And yes, it has to be thousands of kilometers long, as at shorter distances the only advantage Hyperloop is supposed to have over, say, regular Maglev, is just not noticeable. The speed difference between it and, say, Shanghai Maglev Train is not that big. The latter can reach 431 km/h. Musk was aiming for just 2.8 times that... and never got his test to that velocity, as Wikipedia cites a prototype only reaching 172 km/h for its passenger test run, while the Technical University of Munich achieved a record of 463 km/h... And even then, passenger planes achieve similar 900+ km/h velocities, so if somebody absolutely insists to cut an hour from their 1000+ km journey, they can do so already without hyperloop. And stretch their legs while sipping martini in their first class flight, instead of spending the same hour or longer in a relatively tiny pod with no such amenities. The tickets will likely be much cheaper as well, as planes are not going to be as expensive as thousands of kilometers of vacuum tube, and the airline can make money on traveling anywhere there is an airport - including over the ocean. Hyperloop will only have wherever a continuous connection was built, and thus far lower volumes of passengers will need to pay for the considerably higher infrastructure costs... All in all, Hyperloop is an inherently flawed idea. It it extremely expensive to set up, while not being meaningfully faster than significantly cheaper (and proven) alternatives like air travel or regular maglev. And that is before we get into the bizarre 'let's make everything into pods!' obsession Musk has that makes Hyperloop even stupider, both from perspective of passenger comfort (trains are more comfortable to travel in than cars, and pods are basically cars without any of their advantages like being able to drive wherever...) or mass cargo transport (separately loading and unloading hundreds of tiny pods with cargo is inevitably going to be a far slower, manpower intensive process than doing so with a couple of long trains).

I mean, in this case it seems the question of 'Does it superconduct?' is a fairly unambiguous yes/no answer given that superconductivity is not a new phenomenon we aren't sure how to measure, though in the case of that answer being no it might still be interesting anyway. If the answer is yes, the question of why it does seems rather more up in the air. This stuff is well beyond my realm of expertise, but I gather the consensus amongst people who do know what they're talking about seems to be that if it does work, the guys who created it don't really have a credible understanding as to why. * 32 Chrispikula Chrispikula A square inside a circle inside a triangle * Yesterday at 12:54 PM * * #267 Grey Rook said: Is it not also so that if the vacuum tube were to be compromised by, for instance, an improperly sealed door or a tornado launching a cinderblock through the wall at a hundred KPH, the entire network would explode?

This article paints quite a grim picture: At just 3 PSI (pounds of pressure per square inch), air can cause significant damage to a human body with the potential to result in the loss of human life. At 5 PSI, buildings would begin to collapse and fatalities would be widespread. With 10 PSI, reinforced concrete buildings become severely damaged or can collapse entirely. Most people would be expected to die. In the case of the Hyperloop, air would enter the tube at 15 PSI (!) equivalent to one atmosphere or 10,000 kg per square meter. As it enters any perforation, the atmospheric pressure would tear open the tube like a tin can. Any and all capsules that stand in the way would be instantly shredded apart. The results would almost certainly be deadly. Click to expand... Click to shrink... The article also contains a plethora of other engineering and safety issues that make Hyperloop's plausibility questionable. None of them seem to be solvable by superconductors, though. Speaking of which, in order for me not to get slapped for derailing (haha!) the thread: Guderian2nd said: 1. Argonne National Laboratory SNIP: "They come off as real amateurs," says Michael Norman, a theorist at Argonne National Laboratory. "They don't know much about superconductivity and the way they've presented some of the data is fishy." On the other hand, he says, researchers at Argonne and elsewhere are already trying to replicate the experiment. "People here are taking it seriously and trying to grow this stuff." 2. School of Physics, Nanjing University SNIP: On the recent people hotly debated "if really immediately can get the Nobel Prize 'South Korea room temperature superconducting materials LK-99 paper'", July 28, Nanjing University, professor of physics Wen Haihu interviewed to the surging science and technology, said. "It's really buzzing, but it's not surprising because this thing is important." "Most of the (buzz) people are not doing superconductivity." "We carefully analysed their data, and from three aspects - resistance, magnetisation and so-called magnetic levitation - none of them are sufficient to show that it is a superconducting phenomenon (material)." "We judge that (its so-called superconductivity) is most likely an illusion." As for repeating the experiment, Wen Haihu said, "In fact, we didn't even want to do it because we judged that it didn't look like superconductivity, and then we also sent one of our classmates to work on it. Many groups internationally are repeating it. With our experience, (the data published in the current paper) is not enough to show that it is superconducting." Click to expand... Click to shrink... Well, those were some scathing quotes... Particularly the second one. On one hand, the whole strange Nobel-chasing drama makes fraud extremely unlikely, but the likelihood of this being just an overenthusiastic error does increase. Then again, the papers have been rushed, so it is possible that the reasons why the figures look weird is because of that. Or maybe weirdness is expected in that case, it is not like observations not fitting theory must mean observations were flawed. ...please, oh please, let this skepticism be unfounded. This superconductor would revolutionise technology in so many ways... People cannot finish replicating the material soon enough. I don't know whether I should be celebrating or disappointed, damn it! * 24 PeaceKeeper_Cmdr PeaceKeeper_Cmdr Pimping for Justice Subscriber He/Him * Yesterday at 1:24 PM * * #270 Couple things to point out: After 40 years of research we still do not have a good theory of how unconventional (most Type II) superconductors work. Conventional/ classical superconductors (most Type 1s) have been explained by BCS theory since the 50s, but we still haven't cracked the theory behind the others despite decades of trying. If this is real but represents yet another different type of superconductor (a hypothetical Type III) or even just another unconventional Type II then not having any idea how or why it works is really just par for the course. All superconductors have not just a critical temperature (the highest temperature it can remain superconducting at), but also a critical field (the strongest magnetic field it can remain superconducting within) and a critical current (the highest amount of current it can support before losing superconductivity). These last two are linked, because electromagnetism, but it can help to think of them separately. A type II superconductor actually has two critical fields, a high field and a low field. Below the low field limit, it's fully superconductive. Above the high field limit, it's not superconductive at all. Between the two limits, it shows intermediate behavior where regions are superconductive, but there are still places magnetic fields can penetrate. All of which is to say that can be harder to measure superconductivity than you might think. And because we've never figured out the theoretical basis of unconventional superconductors, there's nothing to say that we won't come across a material that behaves in an entirely new way that makes it even harder to test. People will, in all likelihood, be trying to recreate this experiment for years (like cold fusion or polywater) before we can say "not a STP superconductor" with confidence (even a "Yes it is" result would take multiple repeated successes to fully confirm). * 48 Guderian2nd Guderian2nd Your (Eternal and Everlasting) Emperor Administrator * Yesterday at 1:55 PM * * #271 The one from Bilibili (Guan Shan Kou Nan Zi Ji Shi ) has taken magnetization and resistence measurements of his synthesis results that failed to levitate: Guan Shan Kou Nan Zi Ji Shi Ge Ren Dong Tai -Guan Shan Kou Nan Zi Ji Shi Dong Tai Ji Lu -Bi Li Bi Li Shi Pin Bi Li Bi Li Guan Shan Kou Nan Zi Ji Shi De Ge Ren Dong Tai ,Zai Zhe Li Ke Yi Kan Dao Guan Shan Kou Nan Zi Ji Shi Dong Tai Fen Xiang , Shi Pin Tou Gao De Wan Zheng Ji Lu ,Liao Jie Guan Shan Kou Nan Zi Ji Shi De Huo Dong Gui Ji . space.bilibili.com space.bilibili.com 04988925266a8bf8d1d6188c170fedbc7590247.jpg 9e0b1f5ea1bb0f84d512fd7a71a071297590247.jpg His comments: Kang Ci Xing You ,Bi Jiao Ruo .

Translation (DeepL): Antimagnetism is there, relatively weak. Zero resistance is not there, and the whole is just a semiconductor curve, so I guess if there is a superconducting phase, it's a trace amount of superconducting impurities that can't form a continuous superconducting pathway. Click to expand... Click to shrink... Ie. the material is weakly diamagnetic, but the resistance graph is more of a semiconductor. It does not display zero resistence. He posits that if the recipe does produce a superconductor, then it must only be in trace amounts in his sample that do not form complete pathways. He also note that similar graphs of magnetization and resistence appear in the Korean papers, which are the graphs for the "abnormal magnetic behavior" that the Korean researchers observed in some samples back in the 1999s, the results which prompted them to start their research into superconductors in the first place: 03e24d9b216e30c849319784b2bf428b7590247.png Comments: Han Yu De Na Ge Lun Wen Ye Chu Xian Guo Lei Si De Kang Ci Qu Xian ,Kang Ci Zhuan Bian Dian 323 K Translation (DeepL): A similar antimagnetic curve appears in the Korean paper, with an antimagnetic transition point of 323 K. Click to expand... Click to shrink... If so then this could indiate that the 4 samples Guan Shan Kou Nan Zi Ji Shi synthesized actually do contain trace amounts of superconducting material, and that the lack of flux pinning is an issue of purity. Furthermore I've found a link to a (partial) recording of the test live stream that this guy did: Zui Xin Xiao Xi !bZhan upShao Zhi De Si Fen Shi Wen Chao Dao Yang Pin Jun Wei Chu Xian Kang Ci Xing Xian Xiang _Bi Li Bi Li _bilibili Based on these information, I'm now going to mark this person's reliability of claims regarding replication to Somewhat High, as I see no particular reasons to see why he'd fake magnetization and resistence measurement results. I've added the new information to the pinned post. EDIT: I've also changed the pinned post's format into a table, as I felt that a table was easier to read than a list.

To be honest, I'm gettting a bit exited. Still cautious, but if other attempts at making the stuff are finding abnormal behaviors then this might really be something. Still only replicating the 1999 results, but it's encouraging.

Maybe change "room" to "standard". Then it could be abbreviated as a STAPSconductor. If true, I want them to ship some over to the National Ignition Facility. This could make fusion reactor designs practical. Click to expand... Click to shrink... There's a term called Standard Temperature and Pressure, or STP, that works here; STP superconductor. Teiresias said: Excellent. It making Elon Musk right about something would be too horrible to contemplate. Click to expand... Click to shrink... AFAIK even Musk didn't believe in hyperloop, he promoted it to sabotage efforts to get actually practical mass transit built; most of the guy's fortune is tied up in a car company's stocks, afterall. As for this making high speed trains practical; they already are. This would allow even better ones, but the US lacks high-speed rail (and has issues building rail in general) because a lot of people work to block it for various mostly selfish reasons, and even if this can be developed into a dirt cheap mass produced STP superconductor of sci-fi nerd dreams with no real drawbacks, it won't change that.
