Poll: Is LK-99 the holy grail of science?
- Faker than a set of rubber titties
- Yes it's real, I can't wait for my flying car, maglev trains and cheap electricity.
- Duh I'm a fucking dumbo, is LK-99 a breakfast Cereal

Do you understand resistance? -
2023-08-27 at 2:08 AM UTCSo LK-99 was a meme and is not an RTSC, looks like the revolution and next gen of EM technology is still yet to come.

2023-08-28 at 12:42 PM UTC"As of 15 August 2023, no replication attempts had yet been peer-reviewed by a journal. Of the non-peer-reviewed attempts, over 15 notable labs have published results that failed to observe any superconductivity, and a few have observed magnetic response in small fragments that could be explained by normal diamagnetism or ferromagnetism"
A bag of shit as I predicted. -
2023-08-28 at 2:04 PM UTCi could make it i bet

2023-08-28 at 10:20 PM UTCI really haven't seen any evidence or solid argument that an RTPSC is even a thing that is possible within our universe tbh.
The thing about "holy grail"s is, they're mythical. -

Originally posted by Loing Guaranteed if it's even a superconductor at all, they will find that super conductance is achieved only in small fragments throughout bulk masses. And the material is ceramic and not a metal so you can't really form it into circuits well. So basically, close to useless practically in some senses.
However if it's real at all, if there is any RT superconductivity achieved at all anywhere in the material, it will be tremendous news from the research/theory POV. As far as we know from current info, LK-99 is purported to achieve superconductivity with a different mechanism than Cooper pairing, an alternative method involving quantum tunneling through the topogical defects between the material's internal surfaces.
So if it's at all real, it should be the beginning of a feeding frenzy of new RTSC research. And who knows, maybe it will help to produce a real, useful RTSC material that can be turned into wires and formed into circuits.
I don’t really know shit about shit, but I see everyone talking about flying trains and stuff. It seems like you wouldn’t really need to address the engineering issue of forming a material into wiring or patterning it onto a circuit board to make it useful. Just slap it on a carriage and put it in a magnetic field and you’ve got a floating train, right?
For circuitry what do you get out of a superconductor? Like you lose less power to resistance and don’t generate as much heat, but don’t you still have the same semiconductors still generating heat to produce a logic gate? Does charge propagate though a superconductor faster or something? -

Well it won't change much for trains in general. But let's think about trains as an example.
Basically the same reason we use electromagnets for maglev trains rather than just using regular non superconducting magnets. Cuz the "free" levitation doesn't do shit for us if it can barely even levitate its own weight. It's not as simple as more magnet = more levitate, above a certain critical field it loses superconductivity. We wouldn't really care about basic Meissner locking levitation, we would use superconducting electromagnetic levitation to whatever critical current the material could take at operating temperatures.
It would be more powerful and more efficient than basic maglev.
But (to my earlier point that it wouldn't really change much for trains) that's really not the reason maglev hasn't already taken over trainology everywhere anywhere: the electric bill and inefficiencies involved with maglev is basically a meme cost in the grand scheme of things. Essentially a non factor.For circuitry what do you get out of a superconductor? Like you lose less power to resistance and don’t generate as much heat, but don’t you still have the same semiconductors still generating heat to produce a logic gate?

Cuz for example think about an MRI machine, we don't move a magnet around like zoom zoom inside it.
We use an electromagnetic coil that is made superconducting by helium gas cooling. A charge moving around the coil and its corresponding changing magnetic field is used as the "rotating magnet" so to speak.
Already there exist "High Temp" (liquid nitrogen temps rather than liquid helium temps, helium is more expensive) Superconductors that are ceramics. Why don't they use HTSCs in MRI machines? Cuz they're ceramics. Even if you were to just "zoom zoom" them around mechanically, they're brittle and would fucking break. Not to mention that enchanicakly zoomzooming them has a shitload of basic engineering challenges like you literally can't achieve anywhere near the same speeds as sending a charge down a coil (shit is near the speed of light), nor gain anywhere close to the same level of control you can get over radius vs turns etc. And if you could get itnuo to speed, imagine the vibrational stress the casing would constantly deal with for example. And you can't really run current through it while it's moving so you can't use it for electromagnetics, just it's basic magnetic force, and you can't really interface with it directly for resonance information like you can with a coil you just run current through, and make into a powerful superconducting electromagnet.The following users say it would be alright if the author of this post didn't die in a fire! -
2023-08-29 at 8:56 PM UTCOh yeah and the reason we use superconducting electromagnets in MRI is cuz we can achieve higher magnetic field strengths
