Because we give too much credit to intelligence. Intelligence finds patterns, intelligence refines processes. But discovering new shit? Discovering new shit has nothing to do with knowing shit (can even be worse because of preconceived ideas) and all to do with trying and mixing random shit until something clicks.
Art is nothing but remixing existing things + a bit of randomness. Same thing with science.

Holy shit, the egg on their face to have rejected a world changing technology.

And yet they'll face absolutely no blowback for it and the masses of researchers will continue to suck their cock as the "most prestigious" journal.

>>15598881
These Journals are jokes.

>>15598886

Journals are quality control, and that includes both the quality of the research and the quality of the presentation. Both are critical and not being up the snuff in either can get you rejected. Something like 95% of papers submitted to Science or Nature are rejected so that's not even a huge knock against this study.

>>15598649
Who's to say we did? Historically "scientific" discoveries were considered church secrets and thus never shared and lost to time. The ark of the covenant was said to float above the ground and shock to the touch. Sounds fancy but it's just magnetism and a battery.

I've heard claims that this will solve energy storage, but I don't see how. I understand that it would have infinite cycles and no loss over time. But you can't put much current through without losing superconductivity, so energy density would be low, right?

>>15599049
You are correct. It will not solve energy storage, at least directly. Indirectly, however, there will be a lot of improvements.

>>15599049
>>15599065

4 words: big ass floating flywheels.

>>15598784
sovl

>>15599072
you don't use those in vehicles or handheld devices though.
magnetic bearings are already a thing for flywheels. supermagnetic bearings and motors will make them cheaper and somewhat more efficient.
but it doesn't exactly change the grid

>>15598784

>>15599102
The fuck it doesnt. Instead of having high power conections to big centrals like nuclear or hydro-electric you could have local storage that trully scales with the size of the locality.
Renewables would become the biggest source of energy overnight. The grid would be simplified, the load more balanced, etc.
The tecnology exist already, but magnetic bearings and normal motors dont hold a candle to superconducting ones.

>>15599102
We are speaking here about the fucking grid, who cares about the battery of your dildo

>>15599117
you would have to have a vacuum where the disk spins, but I guess if the pumps dont take much energy then that could still be pretty good
I don't remember flywheels having that high of an energy density though
even with levitation + vacuum the disk rotation speed would still be bounded by the physical properties of the disk material, so they would still have a max energy density

>>15598784
Holy mother of based.

>>15599125
God I hope it's legit. Fuck muh professionalism and muh "correct fonts"

>>15599124
>vacuum
Only done during maintenance, negligible
>disk rotation speed would still be bounded by the physical properties of the disk material

You have super efficient levitation, just make the load slower and bigger

>>15599132
I'm also so fucking done with the 'correct' english needed to publish. My language uses long sentences and I like it that way, fucking deal with it

>>15599117
>Renewables would *magically* become the biggest source of energy overnight
>the grid would be *magically* simplified

we already know exactly how well superconductor flywheels can do. We've made them. Subtract the extra cost of cooling, and you'd have exactly what you'd get with RT superconductors. It doesn't solve anything.

>>15598784
Too based to be wrong. We are so back.

>>15599142
my supervisor complained because i used extremely mild metaphor throughout a paper
it was something like "the knowledge can only be found inside the heads of the committee members"

>>15599144
>Subtract the extra cost of cooling
>it doesnt solve anything
You say it like the cost is small or something.
> It doesn't solve anything.
Yeah, let me store this energy using this super expensive, short lived and based on rare materials technology. Or on this one based on some copper, lead and concrete that can be used basically forever.

>>15599149

This, ffs, english have to be the worst fucking language to write papers. Is rather:

>>15599144
>It doesn't solve anything

I'd rather have a few ton flywheel on the side of my house that I can use for 50y than a powerwall that may catch fire in a few

>>15599180
the amount of battery fires happening are greatly exaggerated

>>15599192
Better 0 than low. Lithium batteries will still die in a few years anyway

>>15599197
lmao

>>15599142
>My language uses long sentences and I like it that way, fucking deal with it
This is fucking infuriating, because long sentences are a feature of English.

>>15599160
Or it could be as the paper has shown with their imperfect samples: the ampacity of the material is still far too low to be a useful electrical component and we will need more years of research to a) discover the exact mechanisms for RTSC b) engineer a RTSC material using said mechanism that can be manufactured cheaply and provides the same or equal electrical conductivity to copper or aluminum

>>15599200
Until lithium battery based chemistries can survive for many, many more cycles than it does now, it will never be viable for anything beyond small disposable consumer electronic gadgets.

>>15599200
A flywheel isn't going to lose 30% of its capacity over 10 years.

>>15599180
Wouldn't that still go off like bomb and blow up your whole block if it got knocked down or something?

>>15599197
> Better 0
I bet there's a non-zero chance that something will fail and that flywheel will bulldoze your entire house

>>15599233
you clearly haven't kept up with them lately
they are already being used for grid storage
tesla powerwall is rated for 10 years for instance and that is with cycling once every day

>>15599238
what matters in the end is LCOE
without actually having a room temperature superconductor and making a system, it is way too early to say that they would somehow be automatically win lithium batteries

>>15599223
I'm honestly not that worried about the saturation limit of this material, if it works. It'll be easy to improve and compensate for and it doesn't have to reach extraordinary saturation limits to be able to exploit its superconducting properties.

>>15599250
>tesla powerwall is rated for 10 years
That sounds terrible for infrastructure.

>>15599254
>LCOE
According to simulations, this is better LOCE than lithium batteries but even with superconducting magnets this is a dumb engineering proposal.

>>15599260
Megapacks have a 15 year guarantee, that is pretty good dude

They are covered by a big steel wall. It is also easy to detect problems early thanks to vibrations or simply sound. The risk of sudden catastrofic malfunction is much lower

>>15599258
I am concerned about amperage and other material properties such as what seems to be a lack of tensile strength- which is bad for making cables.

>>15599281
Whatever this material gives, we will take it.
In any case the most interesting part is how it achieves it. Once we know it we will surelly find better compounds for each application

>>15599281
you can solve a ton of things with geometry, laminating into composite material, etc.

Why is there a thread about this random paper? It has nothing to do with the room temperature superconductors you guys are interested in.

>>15599348
>why
you know why

>>15599049
with these thing film superconductors energy density is a function of surface area of the material, and the layers can be built up using standard vapor phase deposition or molecular beam epitaph, which means the process can be integrated as a node into existing semiconductor fabs. As a simple example you could imagine laying down stacks of layers on a wafer prior to building the electronics on top, so then you have a printable battery integrated into the chip itself. Then imagining printing these things on paper or glass or your moms boyfriends dick.

No need for batteries? I thought that it would just create better batteries instead?

>>15600297
superconductors have zero resistance, aka perfect electrical conductivity. that means zero energy is lost from running power through it, which means things like unfathomably efficient battery usage, effectively zero heat generation from electronics, significantly smaller and more efficient wires, etc.

>>15600487
You can run a superconducting superwire into a superloop, and the current will flow forever. So storing electricity becomes trivial.

>>15599262
nice simulation

>>15600497
o I didn't think about that. The heat generation and losses are nearly 0?

>>15600502
0

>>15600497
the problem was already trivial, power generation was already a solved problem 100 year ago. people who want to reinvent the wheel for no reason all have that desire because they are too low iq to figure out how to do something legitimately useful

>>15599180
You don't need superconductors for a flywheel, they already exist with conventional magnetic bearings. Superconductors would add nothing to that.
What you CAN do is have a loop of superconductor, so you can get the advantages of a flywheel but with no moving parts in complete safety.
Unless the temperature goes about the critical temp, in which case it will quench and explode.

We are SO BACK bros!

>>15600505

Bros, koreans don't even know this is happening. there's not a single korean media that is reporting this shit. not sure why users in the west picked up on this so much. some guy who got kicked out of a research group published a crazy paper without the consent of other researchers in the group. of course it doesn't work. it was never supposed to work.

Mechanical parts that can interact without touching (zero friction in a vacuum).
High energy density batteries with instant charging
Rail/coil guns
Way better electric cars
Super energy efficient power cables
Little flying drones that can follow you around all day and do stuff on a single charge (in general anything that wasn't viable due to the battery not lasting long enough is now viable).
Smaller cheaper MRIs and other magnetic imaging technologies
Propellant free propulsion when in the presence of a magnetic field (e.g. Earth's)

>>15600506

Solved, gentlemen.

>>15600895
This is just a horrible comparison for you to make.
Theranos didn't publish papers explaining how their magic blood machines worked, they kept everything close to the chest and weren't found out for years.
LK-99 is easily replicated by anyone with a few thousand dollars and a free weekend, there's no profit motive for faking something so simple.
Now if they had published a paper with a thousand steps that would take five years to replicate, then there's a much better argument that it's fake and the process is being obfuscated.
But we're not seeing that, we're seeing something very simple and the authors fighting over who gets publication rights.
The Chinese took this seriously enough to try and scoop LK-99 before the Koreans ever got to publish, leaving us with this mess of papers that were thrown online in a rush.
Nobody would go to all this trouble unless they were sure they had something real.
They're openly inviting people to call their bluff via replication, even going so far as to offer assistance to any teams willing to visit SK.

>>15600884

ok, maybe it's not a fraud. maybe it's a case of the guy being absolutely dumb or delusional or both. i hear he couldnt get his phd in like 10 years.

>even going so far as to offer assistance to any teams willing to visit SK
imma need a source or an actual account of a team that actually flew over

>>15600924
>yes, and all it takes is the guy going "hang on, better data on the way"
This is just stupid.
We've passed the point of "does the paper have good data" and moved on to "does this even make sense in principle?"
They could publish a dozen new papers, wouldn't change a damn thing.

>we don't actually know what theyre fighting about
Yes we do, don't act dumb.
The authors changing on a paper-to-paper basis is evidence enough, they're worried about getting cut from a Nobel.

>imma need a source
They're already claiming replication.

And before you say the predictable thing, yes we know these are legit chat logs from the actual people involved.
There are multiple sources with identical screenshots.
If you want further evidence you'll have to get on a plane to Beijing.

>maybe it's a case of the guy being absolutely dumb or delusional or both
Convenient how the Koreans are cunning and clever enough to try and trick the world but also somehow dumb enough to just accidentally their way into data that somehow is exactly what we would expect from a SC. >>15600646

>imma need a source or an actual account of a team that actually flew over
I never claimed any team flew over, I said the Koreans offered help to anyone who does.

>>15600940
Can you explain to me what would it mean if this room superconductir is true and how will it change the world?

Like it's just some material but people talk about it like it's philosophers stone

>>15600940
nobody's officially claimed replication. all we have is some literal who's message. that should be all we need to know about this.

>>15600924
>SOURCESROUCESOURCESOURCE????

You still haven't explained how they profit little soijacker

>>15600952
It's been explained multiple times >>15600827

>>15600954
The experiment takes multiple days to complete.
Most people were not privy to LK-99 until the 25th, only three days ago.
There hasn't been enough time for anyone to finish yet.
However, the story goes that the Chinese found the arxiv paper on the 22nd, the day it was published, giving them a head start.

>>15600966
Thank anon

>>15600827
>Mechanical parts that can interact without touching (zero friction in a vacuum).
This is already possible with conventional magnetic bearings.
Hovertrains benefit because you can use flux pinning as a motive force, so there is that.
The real advantage is being able to run current in a loop without loss.
For example, you could have magnetic shielding of spacecraft against cosmic rays. Till now, the answer has always been "yes it works, but the electromagnet is too heavy, or the cooling apparatus for a superconductor is too heavy" That goes away now.
You can also use a loop to store power, much more practical than any flywheel.

>>15600827
And so you've said about technologies, but can you predict what social and day to day changes they may cause?

>>15600978
And how the fuck hover board can work?
What the fuck, does it mean that you can make any thing on earth just fly away by using electricity?

>>15600978
>>15600981
Use your fucking head.

>>15600981
Replaced all sidewalks with superconductor. Then attach magnets to your skateboard and simply hover wherever you want to go.

>>15600987
But can you push with leg though

>>15600984
Dude it's you here who is scientist.
Invention of faster cpus too was insignificant in itself but look how it changed the whole world

>>15600978
See this shit?
https://www.youtube.com/watch?v=7KtzyZKSuls
You'll be able to do that, except you won't have to fill up your board with liquid nitrogen first
>but wait doesn't that only work on that one special skate park
Yes the skate park has to be magnetic
>that's retarded
you're right, it IS retarded.
Room temperature superconductors will no doubt be very useful but we haven't exactly figured out how yet.

I just want an Elysium energy shield :(

>>15600827
Processors would still get hot, heat is from gate switching, not resistive heat for the most part. Still it would help and would be interesting to see what the TSMC yellow autists can do with it.

>>15600990
Yes certainly. It's just like those examples of a normal superconductor hovering over a magnet except you can ride on it.

>>15600997
Imagine this but it pushes off of the Earth's magnetic field.

>>15601001
That could potentially be possible, if you can increase the critical current density to absolutely huge levels.

>>15600975
>This is already possible with conventional magnetic bearings.
To an extent, but flux pinning is by comparison rock solid, and the bearing could carry orders of magnitude more load.

>>15600997
Well I've imagined something more like this..

long thread with napkin math calculating how long it would take to replicate the 1000 experiments with a supercomputer
but the point is basically that its not possible to brute force calculate this stuff right now, you have to physically test
I guess the experimental procedure could be automated if you wanted to run through thousands of different combos like that

>>15601057
what is meant by LK-99 search process?

>>15601046
It's fake though

>>15600511
a superconducting ring would be the mother of all supercaps
I can't wait to build my own plasma rifle from plumb bobs, electrical wire, safety matches and 3dprinted plastic

You're forgetting about lead toxicity. Handling lead is virtually impossible without immediate supercancer.

>>15600810
>MIT believes it to be a a new kind of superconductor with unusual physics.
I piss and shit on MIT beliefs from a great height and with extreme gusto
the best thing that can potentially come out of this is NOT a room-temp superconductor (space is cold enough for YBCO, I don't give a shit)
it's a theory of superconductivity that actually does what a theory should - explain the data and predict new phenomena

>>15600999
> heat is from gate switching
yes but you could switch much faster, so your heat losses would be much lower

>>15601203
its certainly a clusterfuck

>>15601212
it's just like muh korean drama series

could you guys stopping with that one

>>15601267
switching time would be much shorter, retard

>>15601112
they claim to "bruteforce" the research, they make tons of slightly different compounds and tests them to find a superconductor

>>15601279
how? transistors are made of semiconductors. Or are you talking about those fancy superconductor based transistors? i read somewhere that those would be almost impossible to miniaturize

>>15601284
so if they’re not lying these guys have essentially just been randomly boiling shit in a pot for 20 years until they found something that worked?

>>15601304
i mean i am not sure anymore, too much random information, but i think they had an idea on what they were looking for, something that did their dead mentor? or something like that

>>15601304
That's precisely what they're claiming, yes.

>>15599223
>the ampacity of the material is still far too low
enlighten us faggot, how do you know that? show us the info, from any published papers on this material.
let me guess, you're just repeating what other morons said because they can't properly read a fucking paper
the material is a fucking lead ceramic, a fucking brick, fuck knows what and how it forms, it's all still speculation, you have no idea on the conditions of those measurements, yet you somehow surely know "this superconductor does not conduct as much current as other more betterer superconductors"
midwit gossip

>>15601291
the idea is probably to use josephson junctions which are supposed to be very fast. dunno how viable this approach is tho and how many decades away. it's enough for the hopium addicts here anyway

>>15601304
history of science is people banging various rocks together until they get a spark

>>15601112
this is a linkedin post from one of the authors

>>15601304
Yeah, from what I've heard they've stumbled upon trace amounts of the stuff in 1999 and have been searching for a reliable process to reproduce it ever since, though they only got proper financing in 2017

>>15601304
So? This is how science should be done. Known models are just por optimization and prediction but ultimately are always incomplete or wrong. The ONLY way to drive innovation is trying random shit until something sticks. Also ideally make retards be the ones that try the random shit so they don’t have preconceptions of “this wont work because Mr Sponzerotnzowitz paper said so we’ll skip it”

>>15601323
>decades away
josephson junctions exist now, and have existed for decades, only trouble with them is they need to be chilled
did you honestly believe that the guys at ft. Meade run map/reduce on the whole Internet with fucking Xeons?
jesus fuck

Nothing ever happens. LK-99 is a fake. Busted. Party over.

>>15601323
I was talking about those when i said those probably won't be able to miniaturize properly. Still now that i think even if only works on big ones, faster shifting power electronics would be a really big thing.

Let me ask, do (You) hope that this is real?

this one is way more compelling than any other ambient superconductor claim i have seen, but i’m no physicist

I noticed people that think this is real get really mad and emotional which means for them this is just hope of having their miserable lives fixed by miraculous new technology
I'm going to say it's fake

>>15601429
If true material scientists can research why the fuck is it superconductive and create novel malleable materials, not really a problem

>>15601330
Lmao, the potentially most important scientific innovation of the 21st century was literally brute forced by some chinks in a lab, incredible

>>15601439
That's why theorycels are wishing for it to be fake while everyone else is hoping for it to be true.

>>15601430
Those types are just the pathetic Yang Gangers that thought their useless lives could be subsidized fully with UBI bux. Same people are all the 'fururists' and 'singularity worshippers' that believe a future is just around the corner where they can be the slobs they want to be.

>>15601435
not sure what you intend to say, but yea I also imagine its not an issue if you can just deposit the material on a printing board.

>>15601439
If the story is to be believed their dead mentor had a general idea and they were working in that direction. i do hope something happens if only to force a bunch of people to eat crow.

>>15598715
This. Academia is a giant circlejerk and dick measuring contest. It's more akin to Hollywood that to finding the truth. I always distinguish between science(tm) and actual research. Nobody cares for research if 'important people' don't think it's important.

This.

>>15598788
AI is a good comparison. It's great at knowing and combining existing knowledge, but it's useless for prediction and creation as it is completely reliant on existing data. 95% of scientists are the same
>t. phd student
>>15598854
>>15598881
Elitist tier journals are cancer. In a lot of cases, how many blacks, women and 'important people' you have on the paper is more important than its scientific value. I've seen cases in which they had a token elitist who did basically nothing just to get in a high impact journal
>>15601330
>>15601439
This is an actual scientific approach. The usual science(tm) approach is that the principal investigator has a 'great idea'/concept which is easily seen as pure shit by any capable phd student or post doc, then the latter have to try to produce it in the lab and are called lazy or stupid if they fail. Eventually someone makes an accidental, related discovery and the PI sells it as his idea. All contradicting results are not reported.

>>15601369
No shit I want it to be real

what if this is a huge psyop to discredit anything that might "leak" like this one, in the future?
if this fails, and some faggot discovers something, what are the chances of people trying to replicate it, if this one fails?

>>15601545
Same old megastructure circlejerk, like all his vids.

>>15601582
100%, this happens like once every 6 months

>>15601582
Nobody cares. The monetary potential will keep people researching this until humans die out or figure it out.

>>15601582
>what if this is a huge psyop
go back

>>15598642
Read the paper you fat-tailed polecat. Type III superconductors do not expel magnetic fields and do not exhibit the Meissner effect. That means zero resistance but they don't float, get it? We need that sweet floating ability which you have in your fancy floating mountains. Now hand them over!

>>15601598
even without it being floaty we can still pump huge current for powerful fields so we can still make better floaty things with it.
tho being the first of its kind, and things don't yet seem clear, I'd wait until call out its properties.

>>15601605
No that guy is wrong. The paper in OP says that vortex penetration in these theoretical Type-III superconductors happens at any magnetic field strength, up till the critical limit. With Type-II superconductors, that penetration requires a certain minimum strength.
This vortex penetration is precisely what is needed for the Flux Pinning to take place.
So in fact these Type-III superconductors would float even better than normal high-temp superconductors, up until you overload them.

>>15601616
Exactly. Type-II has a critical field Hc1 that is non zero. If field is more than this then flux pinning will happen up until Hc2 where superconducting stops.

Type-III has Hc1 = 0 so flux pinning will happen at any field strength although it need to be strong enough to counter the weight of the Superconducter.

They need to make LK99 that is as pure as possible. This whole shitshow was leaked by that Kwon guy who was kicked out of the Uni 4 months ago. They haven't perfected the synthesis method yet.

are time crystals involved in this whole thing? (in the case if it really works)

for real tho, how does crystallized actual shit look like?

>>15601722
like a crystal

>>15601729
if you think about it, if some god made all of this, there's a chance that we might get superconductive material out of our own literal shit.
brothers, we all know what has to be done. for science!

>>15598573
If it is true, in what should be invested to make good money?

>>15598573
explain to me the difference between type i, ii, iii

Pajeets already reproduced it. It wasn't superconductive. Case closed.

>>15601817
We are en route of being synthesizing sir

>>15601549
He got blown up by an IED.

>>15601813
1 is normal metals. It has Meissner Effect - rejects all magnetic fields. But no flux pinning so can't float in that cool way. If you put it above a magnet it would just bounce away and slide off.
2 is high temperate ones like we currently have. Above a certain field strength, it allows some magnetic field to penetrate it in a controlled way, allowing it to float in a stable way.
3 in theory is a new type that, whorishly, allows shafts of magnetic penetration right from 0 magnetic field. So it should float quite well.

>>15601817
they did not do it properly

>>15601832
>They've already admitted to not following the instructions properly
mexican gang members can cook meth why can't these jeets follow simple instructions

>>15601863
probably bc the first to publish a replication will be on the news, so they are trying to get close enough but faster

>>15601863
There's hidden variables to the "recipe," like ramp heating times.

>>15601833
That is the full thing.

>>15601882
That may be the case but keeping those variables hidden only damages any potential claims. If you want to be the people who created the worlds first room temperature super conductor you would want to facilitate repeatability not hinder it.

>>15601845
so type 3s are made for BMC? thanks
