This is an unreviewed preprint coming out of South Korea. If it’s reproducible it would be the biggest scientific discovery of the last hundred years. It will literally reshape the world.
However, the most likely thing is they made a mistake and the paper will be withdrawn.

But imagine if it’s true.

I believe this with every fiber of my being. I believe it is true because I want to live in a world where it is true.

>>15587663
I want it to be true but nobody would’ve published that research. We’re talking about something that could be sold for $100 billion dollars or even more. I wouldn’t be surprised if you could sell room temp 1 atm superconductors for an actual trillion. But even if you couldn’t, even if you’re the worst negotiator in history, even if you just get a mere billion. Who wouldn’t take that kind of money?

what is superconductor?

>The First Room-Temperature Ambient-Pressure Superconductor
>Ambient-pressure

>Why does LK-99 exhibit superconductivity at room temperature and ambient pressure? This is because the stress generated by the Cu2+ replacement of Pb(2)2+ ion was not relieved due to the structural uniqueness of LK-99 and at the same time was appropriately transferred to the interface of the cylindrical column. In other words, the Pb(1) atoms in the cylindrical column interface of LK-99 occupy a structurally limited space. These atoms are entirely affected by the stress and strain generated by Cu2+ ions. Therefore, SQWs can be generated in the interface by an appropriate amount of distortion(57) at room temperature and ambient pressure without a relaxation. From this point of view, the stress due to volume contraction by temperature and pressure is relieved and disappeared in CuO- and Fe-based superconductor systems because the relaxation process cannot be limited due to the structural freedom. Therefore, they need an appropriate temperature or pressure to limit the structural freedom and to achieve the SQW generation.

Seems extremely simple, but does this make sense? If so, why did it take so long to invent such a superconductor?
If it's wrong, is this still salvageable? Is it still a very highly conductive room-temp material even if it falls short of a superconductor, could the principle be used to seek for better performance alternatives?

That's the video of the effect apparently:
https://www.youtube.com/watch?v=EtVjGWpbE7k

is this one of those situations where it's room temperature but gorillion psi?

Spoilers, it's [another] scam. Every few months another group claims to have room temperature superconductors but it never replicates.

>>15587717
because it's a fraud and so it wouldn't work

>>15587746
well it's a 99.99% chance it's a dumbass sensationalist paper with no validity so that's what it means

>>15587746
we had the tech and we already use it but crazy expensive, only for real important stuff.
making it room temp means it's bound to get insanely cheaper compared to now, and the technology itself can affect basically anything that deals with electricity (well, you get the point).
so there's going to be increases in efficiency, cut losses, some very expensive tech is going to become way more accessible for plebs, and that's about 0.1% of the implications, I'm too dumb to fully understand. maybe some more knowledgeable anons could better explain the most impact this tech could have, if real.

Merely passing through to see what "physicists" thought of the paper, nigger

>>15587779
I'll be real, I'm not a material scientist or physicist. However, the apparent identification of a "room temperature 1atm superconductor" as the ark of the covenant in the field has lead to a crazy amount of fraud. Every year or so we hear about some guy inventing a new room temperature superconductor that always ends up retracted. I just don't think it'll happen soon if at all; if anyone actually finds a 1atm room temp superconductor they would probably publish a patent first rather than a paper. Basically, I'll believe it when the goose starts laying the proverbial golden eggs.

>>15587717
That is weird. I guess you can see a bit of a magnetic lock effect maybe, but if you really managed to make a discovery so fucking huge you'd want to show levitation. Instead it looks like someone's fucking with you by wobbling a magnet in front of a coin.

It could mean very tiny interface between big metal slabs which might as well be high pressure.

>>15587890
Fucking idiot, they're describing thermal contraction after baking which is unrelieved in the material i.e. wigner effect

>>15587895
I know, that wasn't the issue. The issue was the worlds "in the interface" and "appropriate amount", because if I had something that may (or may not) technically qualify as room temperature super conductor but one which had no practical application those are the type of weasel words I would use to describe it.

There is also the second paper which has a pic related of levitation.

>Josephson installed a thin insulator between superconductors and discovered tunneling through which current flows. Tunneling occurred between the superconductors(55). Likewise, if electrons are moved by tunneling between SQWs, the resistance will naturally be zero. Tunneling between SQWs is likely to be possible, as SQWs are expected to be formed at 3.7 Å ~ 6.5 Å intervals in LK-99.
so electrons are fucking teleport in this material? this looks like magic to a simpleton like me.

Fucking magnets, how do they work?

>The situation is different in a superconductor. In a conventional superconductor, the electronic fluid cannot be resolved into individual electrons. Instead, it consists of bound pairs of electrons known as Cooper pairs. This pairing is caused by an attractive force between electrons from the exchange of phonons. This pairing is very weak, and small thermal vibrations can fracture the bond. Due to quantum mechanics, the energy spectrum of this Cooper pair fluid possesses an energy gap, meaning there is a minimum amount of energy ΔE that must be supplied in order to excite the fluid. Therefore, if ΔE is larger than the thermal energy of the lattice, given by kT, where k is the Boltzmann constant and T is the temperature, the fluid will not be scattered by the lattice.[19] The Cooper pair fluid is thus a superfluid, meaning it can flow without energy dissipation.
IMO it sounds like bullshit stretching of a shitty theory to match observation and we don't really know how superconductors work.

>>15588068
What about you? What is your expert opinion on this matter?

>>15587618
>>15587689
I don’t get it why is this so important? What could you make with it? I know superconductors are only cold and make things float or whatever but what else?

bros so like if we make cable out of this, say like a wired headphone cable thickness, could we use it to power a fucking city? without getting warm? or maybe say an electric truck?
would cable thickness be a thing of the past?
I feel like I should spaz out about this but I need confirmation from higher IQ anons before I do it. but I'm building it.

If its real Im asking that cute girl at class out. if gooks made a superconductor by basically sintering the shit out of lead apatite it means anything is possible in this timeline

Not close to 0, but exactly 0.

>>15588105
ok this is fucking paradigm shifting if we make cables out of this. complete network with thin wires everywhere, solves EV charging and fuck me, gorillion other shits. this is fucking insane!!!

>>15588105
that doesn't mean you could pump an infinite amount of current through it(?)

>>15587605
This is arxiv, you undergrad moron.

>>15588051
From what I recall (I'm also retarded so don't trust me) electrons generally don't exist in any discrete form, rather there exists a general area in some field where the likelihood of an electron being there is higher or lower than 0 and all interactions between particles are just the intersections of those probabilities. So with a superconductor it's just a matter of moving the probability of where the energy is to where it should be through quantum tunnels - which from my dogshit understanding is basically a railgun but instead of wrapping the conductor in a coil to have a forward magnetic vector you're wrapping the magnetic field to produce a forward energy vector, rather than guiding it through straight copper like a probability river, free to lose some of its water through the surrounding soil.

>>15588120
What limits a wire's capacity? Heat. Why do wires heat up? Resistance. If there's no resistance then there's no heat, so there's no limit.

does anyone understand the process? is it hard to replicate or scale it? what material are used, lead and copper?

Rail guns, quandumb super cumpooters, unfathomably powerful ai, highly efficient banking system, highly efficient transportation. If this is true we are making another huge leap in technology.

>>15588094
classical computers that don't heat up like crazy
lossless power lines (this is huge)
quantum computers that work at room temp (this is even huger)
various kinds of particle accelerators (tokamaks, ion drives, etc etc)

>>15588139
there's a current limit in any superconductor
for this one it seems to be particularly low, which makes a lot of sense

>>15588091
I don't know shit dude, I just study homeomorphisms between funny manifolds

>>15588167
>for this one it seems to be particularly low,
how much currents can it take? why would the current be limited with 0 resistance? I'm not disagreeing, just curious to understand.

>>15588167
how difficult would it be to make a circuit to manage high currents in series?
also, what about electronic circuits, micro processors and stuff like that?

>>15588177
nta, I'm not sure, but the graphs at the start of page 3 show something like 25mA

Even if everything in this paper is true, the material as it is might have limited applications.
From what they show, the critical field and critical current seem very low. 2500 Oe is like 0.25 Tesla. Even REBCO at 77K is >1T. And 2500 Oe is not even at critical temperature but much lower. From skimming through the article I couldn't find the sample size of the current measurement to get the critical current density, not just current which is meaningless (and around 300 mA).
This means you can't actually push big current through this thing (yet). You can't make a powerful magnet, and you can't make viable power lines, both applications that were the hallmark of "room temperature superconductor revolution".
Of course, maybe one or a few more tweak(s) of the material and boom, it will give high J_c and B_c. I really hope it does, it would be super cool!

>>15587751
repli-whats now?

>>15588181
>nta, I'm not sure, but the graphs at the start of page 3 show something like 25mA
298K is ~25 degrees C. that shows about 250mA. higher temp seems to limit the current.

>>15588177
>how much currents can it take?
it is unclear from the paper, they say 250 mA for a thin film but they don't give the width
>why would the current be limited with 0 resistance?
It's only zero up to a limit, then it starts behaving like normal stuff. I'd have to explain ~all of modern physics to you to get at the why, and perhaps write up some new physics and I don't feel up to it right now
let's just say that electrons DO move around in a conductor of any sort even though it's not their motion that propagates the electric field
if they move around too much, due to current or heat, the superconductor isn't super anymore

>>15588186
>Verbatim repost of a HN comment
Is this a bot ?

>>15588181
>nta, I'm not sure, but the graphs at the start of page 3 show something like 25mA
nvm, it shows different ranges for different temps. -25mA to 25mA for 398K, ~ -250mA to 250mA for 298K, etc.
but again, don't trust me

>>15588192
yeah

>>15588181
>how difficult would it be to make a circuit to manage high currents in series?
not at all
>what about electronic circuits, micro processors and stuff like that?
if you can deposit atom-thick films of this stuff, classical computing becomes much cheaper in terms of energy usage, and quantum computing at room temp becomes possible, which is beyond mindblowing

>>15588202

I don't think that's how it works. They knew what they were trying to create, I don't think this was once of those accidental graphene-type deals. that requires to build on other knowledge, invest money in gear, have people trying to make something using various techniques, I think there's a lot of smaller steps that are not obvious. also helps to have friends in the industry, you might get access to random needed details along the way. all these conspire for one of the teams to come up with it faster, than if any random neet would decide to start inventing superconductors at home. I mean they could, I'm just talking about probabilities here.

honestly looks nothing like YBCO meissner effect. it behaves like it’s pinned on a single axis rather than two axes. is this because LK99 is just a 1D superconductor?

Interesting thing about parallel superconductors is that the magnetic flux threading the loop has to be an integer number of flux quanta. This results in a number of valid configurations of passing some current I from one junction to the other, where there's some variable current flowing through the loop in a circle in addition to the net current flowing between junctions.

Above text is for a loop that looks like ---[==]----

I haven't heard of any superconductors being not exactly 0 ohm. That'd make them not superconductors

For the sample synthesis of the LK-99, the general solid-state reaction was used. Lanarkite and
Cu3P were uniformly mixed in a molar ratio of 1:1 in an agate mortar with a pestle. The sample
was put into a reaction tube, sealed under the vacuum of 10-5 Torr and reacted at 925°C for 10 hr.
After the reaction, a dark gray ingot was obtained reproducibly and then made into the shape of
thin cuboids for electrical measurements. For other analyses, it was pulverized and used as the
form of powder. The reagents used for the above solid- state reaction was PbO (JUNSEI, GR),
PbSO4 (KANTO, GR), Cu (DAEJUNG, EP), and P (JUNSEI, EP).
1) Preparation for lanarkite, Pb2SO5
PbO and PbSO4 powders were uniformly mixed in a molar ratio of 1:1 in an agate mortar with a
pestle. And then, after the sample was transferred to an alumina crucible, it was reacted at 725 °C
for 24 hour in a furnace. After completion of the reaction, white sample was obtained. It was
pulverized with the mortar.
2) Preparation for copper phosphide, Cu3P
Cu and P powders were mixed in each composition ratio. And the sample was transferred in a
quartz tube. The tube was sealed under the vacuum of 10-5 Torr and reacted at 550 °C for 48 hour
in a furnace. After taken out from the tube, a dark gray ingot was obtained and pulverized.

>Electrical resistance of type-II superconductors measured by a dc method is related to the motion of Abrikosov vortices.

I think thats what I was thinking of. I recall the word vortices

>>15588511
>In superconductivity, a type-II superconductor is a superconductor that exhibits an intermediate phase of mixed ordinary and superconducting properties at intermediate temperature and fields above the superconducting phases. It also features the formation of magnetic field vortices with an applied external magnetic field. This occurs above a certain critical field strength Hc1. The vortex density increases with increasing field strength. At a higher critical field Hc2, superconductivity is destroyed.
Looks like if your sample is cool and has a low field it'll still measure 0 resistance.

Wait, just how quickly could you charge a really big capacitor with this? Because its my understanding that charge times are the weak link in directed energy weapons right now

>>15588466

it would literally charge instantly and discharge just as quick

Did you post this "understanding" on /k/ about a month ago and I called you a retard who's never seen an RC circuit?

>>15588794
It's not a capacitor. You could make one out of this material but it's not going to be anything special and maybe wouldn't even superconduct when you start charging it

>>15587605
Looks like fraud to me. The paper is written like shit.

>>15588803
No that was someone else
I mostly just post in Ukraine threads these days

So what’s the consensus? Is this thing for real or what? It sounds too good to be true…

>>15588806
Alright. Charge times are indeed the weak link but it's because of the power supply, not the caps. Caps can discharge basically instantly. Maybe a superconducting capacitor would be useful for some experiments or future tech but not anything immediately practical

>>15588094
Another thing is that motors could be generally made smaller for the same power output. Motor are limited by current density which is normally 2A to 8A per square millimeter. Something like this can greatly increase power density (Power per unit volume).

Something like 2% in the big transmission lines and another 3-5% in distribution. Superconductors of this kind will almost certainly be far too expensive to use for energy distribution. So realistically it can't be applied to energy grids or transfers.

That's what I said. you mistake realism with pessimism because your brain is absolutely rotten. If they actually had something that could be used to transmit electricity cheaper than current cables they wouldn't have lead with tech jargon but with "hey we made this cable here, it costs this much per kilometer and can transmit this much power". Lot of brain rotten tech bros have this problem where they think that mere existence or even possibility of some kind of technically better solution to some imaginary problem regardless of cost means that it will be used regardless of cost or practical limits.

>, and were aware that non-toxic alternatives existed,
Like what?

>>15589009
I'm sure long distances will somehow make the cable cheaper... because it just will!
In real world transmission losses actually get lower and transmission gets cheaper with increased distance because you can realistically use higher voltages. Over a 1000km distance you are only looking at 2% with best cables today. If your super conductor isn't competitive on a local scale where demands are lowest and losses are highest it won't be on a longer scale where regular cables get more efficient. The obviously conclusion you should reach from this is that the reason power isn't moved far isn't because transmission losses grow too big but something else, can you figure out what it is?

>>15589010
I just reiterated the point which you refused to address, which is the cost. It's simply infeasible to try to spend orders of magnitude more on a wire that transmits 100% of the power instead of 98%. It's not competitive technology.

>>15589017
Their own specs clearly state the material is not suitable categorically for power lines. It's magical thinking to believe that things will just get solved because they just will! It's not a "scale of production" issue. When they first figured out copper conducts electricity they didn't go "well it only conducts 2% now but I bet with bigger production we can up that to 98%", they went huh this element conducts 98% electricity, now we just need to make lot of it.

>>15589016

This is not an interesting application. You can minimize distribution losses by going to ultra high AC voltages. Double the voltage and you halve the current, losses are proportional to the square of the current

the first transistor was a massive bulky piece of shit that needed a vacuum
the first steam engine was incredibly inefficient, expensive, needed special new fabrication methods, and dangerous
the first forged metals were (probably) impure pieces of crap with more rock than metal

He’s just another retard trying to feel smart anon

>>15589049
Even at 13% losses the super conducting cable can at most cost no more than 15% to be viable and that's not going to happen. Furthermore that's not actually a thing that even exists.

>>15589054
You are making a false equivalence, there's no guarantee that the tech will improve and the things that worked for those such as miniaturization or more pure manufacturing won't help it compete in the energy transfer business according to their own methods. It's a fundamental problem. You may also notice that those first crappy things still worked at their jobs. The jankiest of transistors were immediately obvious to be superior to the previous vacuum tube tech in price and performance and went to mass production pretty much immediately. The first steam engines were immediately useful in things like operating coal mine water pumps, the first forged metals were immediately useful in making stabby things. None of those things were "let's increase the efficiency of a cheap thing by 2% at massively increased cost".

More over you fail to provide any substance, you simply state that things will (somehow) improve because they will and that's the end of the argument.

>you're basically arguing that if something doesn't spring out of the lab fully formed and ready to take over the world within a decade it's worthless
Most things are like that so even if I was saying that (which I'm not, I'm simply saying that according to their own words the tech is not feasible for power transmission) I would still be correct most of the time.

>>15589183
Hmm no I don't buy this. Dias paper was also "high quality" and, in addition to nice figures, it also had some vague theoretical justification (electron-phonon coupling does exist)

OK explain to me how it achieves 0 resistance. I get that it's the crystal structure of lead with copper atoms, and it makes use of the quantum tunneling effect, which is quantum particles passing through reeeealy thin surfaces, but how does that effect prevent resistance? Is it like... Electrons hop from copper atom to atom and the tunneling just itself is 0 resistance?

when they flow as cooper pairs there is a band gap that eliminates some low energy states
as long as the collisions between the cooper pairs and the material lattice are lower energy than the minimun energy level the pairs can take, they don't "really" collide and no energy is lost

>>15589380
what why? I don't understand your question.
Do you mean why it wasn't possible before? Because the Sahara is huge and the distance between those solar panels in the Sahara and the population centers in MENA and Europe are even huger. At these distances, with the huge system loss and expensive transmission lines, it simply wasn't worth it. This'll make it much easier to transport that electricity with much less loss.

Even if it's not practical, it would still be informative as a research step leading towards something better. Superconductivity is very poorly understood, everything helps.
That's if it wasn't a gookscam, which it is.

Egypt is fine.

>>15589410
Even if it was real, it really doesn't. The transmission losses are the least of your concern in bringing power from africa to europe and have never been the actual reason why it hasn't been done before. This doesn't contribute to that anyways one bit since it's not competitive technology for power lines.

ok, I might be stupid, but I don't think a diamagnetic material would fall to the magnet like the sample does at ~0:22
on the other hand, if it is as they claim then it breaks down under an even slightly strong magnetic field; being in contact with the magnet might be enough to turn the superconductivity off and stop the levitating force.

>>15589422
pretty sure it was one of the biggest concerns, along with cost. This'd reduce both transmission loss and prices.
>>15589418
Kinda still is, but there's been a lot of strides made in energy storage that makes it easier. Check out Tesla's battery storage.

>>15589462
No it won't because it will cost way more than regular cable, which along with political problems is the actual reason why it's not done. Transmission losses are entirely irrelevant because the 13% you lose from putting your solar panels to Morocco or what ever instead of Essex you gain in efficiency increase.

>>15589486
It's not the transmission losses but the cost of the transmission. Notice how if you say increase the cost by factor of 100 or more to make the cable superconducting to gain 13% more power it would have made more sense to lay down a second normal cable instead? Do you understand how that works? Indeed you do get blown out super easily.

>>15589514

lol, lmao even

I was at a conference on strongly correlated electron systems in Seoul just 3 weeks ago and as a materials scientist and physicist I can assure u guys this article is horseshit
if you want to see something actually legit, new and very close to this (but not quite ambient pressures) look up the new papers on a lutetium hydride compound by the Dias group in Rochester, USA. They found superconductivity at room temperature with "only" 10 kbar (a factor 10+ lower than the norm)

>>15589486

So hecking epic

>>15588773
>25c
thanks

>>15589519
?
Super conductors at room temperature that are commercially competitive aren't a real thing
2% is figure that's lost per 1000km in high voltage over ground power lines, it's also the average loss of electricity in USA due to transmission
13% is what happens when you draw 3800km of undersea cable, which is not the same as ultra high voltage over land cabling, 3.5 per 1000km is perfectly reasonable for such cable. 13% is also not a big number, again the same panel with a 13% penalty still makes more power in morocco than it does in essex. This also ties back to my earlier point that power loss reducing methods already exist, they could run that line with ultra high voltage cables instead to drop the loss down from 13% to something like 7-8% but it probably make financial sense to do that.
>actually it's not even about that it's something else entirely
The project isn't hindered by the 13% loss at all as per above, but the billions it costs to make the cable, swapping the billion dollar cable with a trillion dollar super conducting cable wouldn't help the financial viability of the project.

Indeed, lol, lmao even

>>15589545
Well I'm sure you can quote the proper number then since you made and claimed it will reduce cost. Factor of 100 is quite good estimate of the conversion cost between simple wire and superconducting system as things are right now, which paper in the OP agrees with.

>>15589549

>>15589551
we did except at high pressure. this is room temp, ambient pressure. or fake.

>>15589554
>Factor of 100 is quite good estimate of the conversion cost between simple wire and superconducting system
>which paper in the OP agrees with
I didn't see any such thing. You made that up just like your other headcannon.

>>15589538
you may also need to consider that superconductors, if they allow enough amps, will not need as many power electronics due to the lower high voltages, which would cheap the other parts of the infrastructure
The part that doesn't make sense is that they want to connect morocco with england without going through europe. They have gibraltar just do that way and sell to the spanish/portuguse energy market and put a connection to england in bilbao or wherever if they want to avoid france

>>15589565
>if they allow enough amps
OP's system doesn't allow this, it allows significantly less than what a regular ol wire would so that's not exactly an argument in your favor. The transformers I would also classify as the cheapest bit out of the generator (such as the solar field in morocco), the cabling and it's immediate costs and the transformers at each end so even if it did make those bit cheaper it's more of grasping at straws thing.

>The part that doesn't make sense is that they want to connect Morocco with England without going through Europe.
That's the part that makes sense, the primary reason for why these projects don't happen is political, running the lines over land trough Spain and France would in fact reduce transmission losses but incur political costs, especially now that UK is out of EU. The secondary reason being cost, which isn't exactly helped by the undersea cable but can be helped by direct country to country negotiations.

>>15588049
this is it boys, it's real this time, I can feel it in my bones. If it isn't, it's so trivial to reproduce that we should know within a week to a month.

OP paper doesn't address the cost of cable made from this thing, which means it's at best competitive with other similar products, but probably not and more expensive, otherwise they would advertise such feature.

There's no indication as to why it would be cheaper, and many indications that it wouldn't be, such as how it can't handle current, that the effect happens at interface layer, the fact that other similar products are just as expensive ect. The indication that it will beat regular wire? It just will ok....

>>15589588

This material is shit, but if it is real it shows how to do superconductors in sane enviroments with a new approach so it would be refined and get better performance with other materials processes parameters whatever
And trusting morocco more than the eu countries is just plain retarded

For starters, a superconductor would need much less cross section than standard cables. So there's one.

>>15589596

There are no other similar products you schizo

>>15589597
It's what other similar products cost, which is a reasonable baseline to begin discussion, you claimed it was cheaper to which I responded that it's not. It's magical thinking to assume it just will be cheap!!!

>We're discussing hypotheticals.

>>15589602

Which is totally irrelevant to what I'm saying, but hey palpatine might show up and just start force lighting us free electricity too!

>And trusting morocco more than the eu countries is just plain retarded
You need to trust morocco to put the panels in morocco. Also the undersea cable minimizes trust in morocco because the lines don't have to go trough the bits of morocco with people in them, which is huge plus.

>>15589605
>For starters, a superconductor would need much less cross section than standard cables. So there's one.

>>15589678
The person I responded to claimed to KNOW it was not only viable for powerlines which is itself entirely unproven and OP's paper seems to contradict that basic statement but that he also knew that it would be cheaper as well. That's the basis for this discussion. I'm saying nothing about it looks like it would make it viable for powerlines and that all sensible logic states that it's not.

The simple reality of the situation is that you operate on the premise that anything that's not explicitly proven false is true and so it must be cheaper because wizards will fix it and avengers will build it
I operate on the premise where things that are proven correct are true and logical things might be true and when someone is THIS insistent on avoiding the topic of cost then it's fairly obvious that they have nothing and will never have anything.
