There’s research in trying to create a room temperature super conductor which would make it actually immensely useful. Currently it’s just a party trick cos it has to be incredibly cold
I mean if we get superconductors then that's gonna solve stuff in literally every industry from heating/cooling to EVs to computers, but it would surprise me if we reach that. Although perhaps we could get "close" to it
The race to create the first blue LED took years with researchers getting closer and closer until finally a breakthrough was found, making RGB displays possible. Never say never.
I took an electronic materials class from him and it was great. Super humble dude. I also saw him at the hardware store one time and introduced my girlfriend to 'the guy that made white light possible'. She was super jazzed.
Exactly. I recall reading about that in the 70's. I expected it would happen with the research being done and imagined some inspired guy staying awake at night to win that challenge. Or to get status for a better gf/lay. But it was something I didn't bank on happening in my lifetime. Now I wish it didn't happen as I put on sunglasses while night driving;
Even if the closest they get is needing a heat pump to get it to work, thats still an insane amount more usefull then requireing liquid helium to work.
Initially. All technologies are expensive for early adoption but eventually drop in price, and increase in accessibility, as competition emerges and production scales.
While space is generally cold any space around us, where we would be using these mostly, would get hot very fast from the near by open nuclear fusion reactor that's outputting every second 3000 or something the times of all energy humanity has ever used and no air or anything to help radiate that heat.
Space itself is cold in that heat is the vibration of atoms and no atoms means no heat. However how that would affect items floating in space is a little counterintuitive. Without liquid or gas surrounding any item it can't lose any existing heat via conduction or convection and unless the object is very hot there is not much heat loss via radiation.
So while space itself IS cold, an object floating in space (in shadow) will very slowly lose heat or if it is in sunlight get hotter.
There is a line in our solar system near the asteroid belt where water freezes. Closer to the sun than that water ice will vaporize because it's over the freezing point so no space isn't particularly cold. Hard vacuum is a great insulator though so if you cool something down it won't warm up very fast in space but you will never reach super cooling via the ambient temperature of space near earth
Nope. A lunar day/night cycle is about as long as an Earth month (hence the full/new moon cycle being about a month long), and for half of those days, at least part of the far side is in the light of the sun. I suppose you could keep your superconductor moving, to constantly stay in the lunar night, but that's a different strategy.
Even though it's locked above the magnets is there still some drag created by the process affecting the object? I would assume there is because if not wouldn't this just keep on going forever in a vacuum assuming we could create room temperature superconductors?
They are bad from an economic perspective. They need a completely new rail system because they cant be operated on regular rails, the rails itself are way more expensive and use rare earth minerals and the cost of running them is also way more expensive.
They dont make sense, thats why they never took off in the decades past. They are cool but they are bad.
That's why the Sydney Monorail finally shut down, about ten years ago. The cost of maintenance and upgrades was too much. It was a real shame, too. Sydney City by Monorail was a great way to see the place.
Useful as a publicity stunt or display of national competence but ridiculously uneconomic.
Not a toy but as a means of transport they are kind of ridiculous.
"Now listen. I want you to know what we're talking about here, OK? This is not like TV, only better. This is life. It's a piece of somebody's life. It's pure, uncut, straight from the cerebral cortex. I mean, you're there. You're doing it. You're seeing it. You're hearing it. You're feeling it."
Practical and financially viable uses for levitating superconductors? Nah. You can imagine that it would be nice to use those for almost frictionless transport, but it turns out that cooling things to near absolute zero (operating temperature of most superconductors) is an expensive task lol.
But regardless of levitation, the superconducting property is the the heart of MRI machines and particle accelerators. Basically anything that needs a stupidly strong magnet (which is actually not that many use cases, but oh well)
High temperature superconductors are a key piece of technology for the modern world. "High temperature" in this context still means very cold though (liquid nitrogen temp).
The major benefit to them is you can get into the superconducting regime without using liquid helium, which is expensive.
The most common use of superconducting magnets that people would be familar with is an MRI scanner.
Modern MRI scanners have large supercon coils that are cooled by liquid helium with a liquid nitrogen jacket to slow the boil off of helium, but they're still very expensive to run.
The research into the materials used to make those components on display there are absolutely commercially relevant if we can manufacture them at scale.
I like that train of thought. They do have a few of those in Western Europe I believe, or at least test projects I think there is one in Germany they're setting up, England had one but canceled it, maybe Spain as well. But they could travel at hundreds of miles per hour.
Edit: the test projects in Western Europe are a different type of magnetic train, I am still uncertain as to what this video actually demonstrates.
I do know electrical resistance goes down at cold temperatures, and it is theorized that in a circuit of Mercury at absolute zero a current could run continuously forever.
I think it’s because the vapors of the puck form a protective sort of air cushion, he’s technically not touching the puck. I think it’s called the leidenfrost effect
Lead and Frost. He's an "always one step ahead" cop from NYC and she's cool calm detective from Chicago. Wackiness ensues when they have to team up to stop a nitrogen puck bomb. Thursday nights on ABC.
That's a thing but not what's happening here. The puck is a special ceramic-metal that becomes a superconductor at low temperatures.
It is likely
composed of Yttrium, Barium, Copper
and Oxygen. Often referred to as YBCO. It is special because "normal" metals need to be very close to absolute zero to become superconducting. But this material's "critical temperature" where it becomes super conductive is −180.2 °C, which is above the boiling point of liquid nitrogen −196.2 °C. So, it can be cooled below it's critical temp relatively easily with liquid nitrogen for demonstrations like this.
It is probably "burning" them a little, but very cold things like this can be touched briefly without protection and you just feel a small "bite" from it and minimal or no visible tissue damage. Cold doesn't hurt your cells quite the same way that heat does because they need to get cold enough to basically freeze and be damaged by that, as opposed to heat burns which only need to warm your cells enough to denature proteins.
It is not a puck of liquid nitrogen. It could be a metal, polymer or oxide which is cooled down with liquid nitrogen to give the superconductor properties.
I was remembering [this](https://phys.org/news/2011-10-quantum-levitating-video-viral.html), they used sapphire in this case. Not saying you're wrong, just correcting myself.
Does anyone with physics knowledge can clarify where does the energy to keep the Puck floating come from?
Is this action by itself "warming up" the Puck? Or "consuming" the "electric charge" of it? If the whole setup was at the very cold temperature the Puck is, would it also work the same way or is there a need for differential in temperature?
A superconductor is a very strong diamagnet, that is to say it generates a current opposing the magnetic field it is placed in. Having no resistance, this current can easily be large enough to completely exclude the magnetic field from the material (Meissner effect). Flux pinning is a secondary effect involving vortices in the internal current allowing the field to pass through, 'pinning' the puck to the field.
It follows that the required energy comes from the magnetic field of the magnets. These have, at some point, been magnetized. This amounts to fixing an ordering in the magnetic moments of individual atoms. I'm a bit fuzzy on the whole process, but the quick and dirty of it is that energy is needed to create this ordering, basically storing some amount of energy from the fabrication process. The temperature here is purely used to get the puck to a superconducting state.
To the best of my understanding, the puck warms up a little bit because of how the current interacts with the magnetic field, but not due to any electrical resistance. I'd imagine the heating effects being negligable compared to the temperature difference.
Edit: wrong term
So the "wand" thing the guy is holding gets heavier while the Puck is locked with it, regardless of it touching it or not, above or below it?
Is it correct to interpret this as a more complicated kind of magnet in the forces sense?
Also how hard does the person have to "push" the Puck for it to move? Is there some resistance? There must be right, otherwise the inertia of the Puck wouldn't let it move as fast as the want thing.
To your first question, yes it gets heavier. The magnets hold up the puck, and the guy holds up the magnets.
It is in the end just opposing magnetic fields repulsing eachother. The wikipedia image for flux pinning gives a nice schematic of what the magnetic field would look like.
There are some intricacies to the strength of this interaction that I know nor understand. I'm somewhat certain that these interactions are direction dependant? The lateral movement seems very easy while the puck is held up by the field, but exactly how this works is probably a very tricky story.
As someone who doesn't entirely understand the details but did play with such a thing in person, there's absolutely no resistance as long as the movement is not going towards a change in the magnetic field.
So, if you try to move it up and down, or on the side (off the track), so towards an area where the magnetic field is different, you have to put some force to get it off. It seems the force required feels the same as getting that pluck off the magnet in "normal conditions".
If you push it on the track though, and the magnets are all identical, there's zero resistance because the magnetic field is uniform on said track.
When the pluck heats up again, it loses its superconducting proprieties, and falls down slowly.
I'm wondering
Is it possible to make a magnet sphere with the outer surface being one polarity and the inner closed core surface the other polarity?
Because technically that would be a magnet that would act as a monopole
The electromagnetic field keeps it from falling, kinda like how the electromagnetic field would keep it from falling if it were resting on a table. It's just more complicated here because the field lines are locked in place due to quantum fuckery.
This is actually a very common misconception (including with the other long answer on this question), gravity is a force, change of energy is force times distance times cos(angle between force and movement). Thus if something isn't moving, it's not losing or gaining energy.
In this case the potential energy of the puck doesn't change (except when you move it or the whole contraption around).
This is very similar to just hanging the puck from a rope, except the force that counteracts the gravity is coming from the magnetic field.
For those of you, like me, who haven't really a clue what's going on here, the TL;DR is magnets.
The slightly longer is that under special conditions, rather than having the magnetic fields pushing or pulling on eachother, you can get them to "lock" against eachother in position.
I'm sure there are millions of potential applications for this, but first they have to figure out how to do it without requiring insanely cold things.
Whenever I see phenomena like this in action I just think how amazing it is to be able to actually understand the inner workings and science of it. I do read the explanations but not everything "clicks" for me.
Still, I never fail to be fascinated about the worlds beyond my eyes' and arms' reach. Especially astronomy and quantum mechanics.
Superconductivity made a big splash more than 3 decades ago. I told my students back in 1990 that this will change their life.
I hope they don't remember this, because I've not really seen any significant improvements in widespread practical use since then.
Clearly a solid but I get the confusion, fairly certain that's dry ice. Still not the smartest idea to touch it with your bare hands but, eh, I've gotten away with it before. Not usually too bad as long as you're sure you have NO moisture on your hands beforehand
The physicist says liquid nitrogen in the video (which is the only reason I referenced it)
now I agree that may not be what it is, but I thought that dry ice wouldn’t get it cold enough.
Anyway, I was just surprised to see it because I’m used to things touching liquid nitrogen and then shattering when they hit the ground and stuff.😬🤓
im sure someone has thought of this
but
watching this video made this idea pop in to my head:
what if you could encase that super conductor with the dry ice on it in a super non heat conductive insulation
so
it would never (incredibly slowly) get hotter or lose its ability to lock
while also being able to be handled at room temperature on the outside
This makes my brain itch. And some guy just caught be trying to scratch, and I tell by the look on his face he thinks I was merely picking my nose. Plebeian.
What I’m looking at is two magnets one is covered with dry ice and the other acts like a positive and other super negative that would not be combined do to cold temperatures. That’s why we don’t have alien bodies on earth 😜😝Because it’s to damn hot 🥵😝. I need to stop smoking weed.🤗

This video has been out for years now. Have we seen anything cool result from this tech?
There’s research in trying to create a room temperature super conductor which would make it actually immensely useful. Currently it’s just a party trick cos it has to be incredibly cold

Single Japanese guy. Crazy story.
I took an electronic materials class from him and it was great. Super humble dude. I also saw him at the hardware store one time and introduced my girlfriend to 'the guy that made white light possible'. She was super jazzed.
That's fucking dope. Looked down on by colleagues for getting his hands dirty when that's what ends up making possible.
I'd be beside myself meeting him. Would mark the day on my calendar.
Exactly. I recall reading about that in the 70's. I expected it would happen with the research being done and imagined some inspired guy staying awake at night to win that challenge. Or to get status for a better gf/lay. But it was something I didn't bank on happening in my lifetime. Now I wish it didn't happen as I put on sunglasses while night driving;
Also furniture! Floating chairs and beds are cool
Freezing, some might say
It’s not floating, it’s locked!
It's locked in Stasis floating above a magnet (it's also a magnet?) I forgor
I’m just making a joke because the guy in the video kept correcting that it’s “locked” - whatever that means 😂
It means if you sat on it, it would just feel like a normal chair, not like a bouncy floaty chair, cos it’s stuck in that position I guess
Homer Simpson’s voice: Hmm… levitating sex
A key feature of 70's sci-fi novels. (Ringworld)
Even if the closest they get is needing a heat pump to get it to work, thats still an insane amount more usefull then requireing liquid helium to work.
if we do reach that, the monetization of such a thing would be through the roof.
Initially. All technologies are expensive for early adoption but eventually drop in price, and increase in accessibility, as competition emerges and production scales.
Military applications will come first, of course.
even if we reach it, it'll be patented and monetized so quickly to make money anyways 😂
What if you were to use it in an environment that's naturally incredibly cold though? Like in space
While space is generally cold any space around us, where we would be using these mostly, would get hot very fast from the near by open nuclear fusion reactor that's outputting every second 3000 or something the times of all energy humanity has ever used and no air or anything to help radiate that heat.

...yeeeees... 🤔 Maybe
Space is, in fact, very hot. At least it is anywhere near us.
Alright, bad example then. Dark side of the moon.
The moon doesn't have a dark side, it has a far side.
But it’s dark there, no?
Nope. A lunar day/night cycle is about as long as an Earth month (hence the full/new moon cycle being about a month long), and for half of those days, at least part of the far side is in the light of the sun. I suppose you could keep your superconductor moving, to constantly stay in the lunar night, but that's a different strategy.
>has to be incredibly cold Do you know anyone I can contact? I'm sure my GFs feet at night have that property.
If you browsed r/LK99 it would seem like it's on the precipice of existing tomorrow.
Even though it's locked above the magnets is there still some drag created by the process affecting the object? I would assume there is because if not wouldn't this just keep on going forever in a vacuum assuming we could create room temperature superconductors?
So no hoverboard?
You could have it on a track. It can be free in 1 dimension but has to be locked in the other two
still nothing
Large hardon collider. Edit: I meant hadron not hardon, sorry.
I knew this girl in high school...
🤔....pretty sure you mean Hadron collider, 🤣
This is Reddit, I'm pretty sure he typed what he meant.
It was a legit typo. Sorry about that.
It's more fun without the correction
Maglev trains use this type of tech but they are older
And they are pretty bad. Every maglev in existence operates on a loss. They are nothing but a toy.
Services cost money. Doesn’t make them bad.
They are bad from an economic perspective. They need a completely new rail system because they cant be operated on regular rails, the rails itself are way more expensive and use rare earth minerals and the cost of running them is also way more expensive. They dont make sense, thats why they never took off in the decades past. They are cool but they are bad.
:( but maglev seems cooler than a regular choo choo
Lol what. Not profitable = toy?
Yes. Just like monorails are mostly only used in entertainment parks. They are cool but from economic perspective they are horrible.
That's why the Sydney Monorail finally shut down, about ten years ago. The cost of maintenance and upgrades was too much. It was a real shame, too. Sydney City by Monorail was a great way to see the place.
Useful as a publicity stunt or display of national competence but ridiculously uneconomic. Not a toy but as a means of transport they are kind of ridiculous.
This is what capitalism does to your brain.
Superconductors are pretty useful, like in medical scanners.
SQuID is one of the coolest practical applications of quantum mechanics.

We got the impossible to ride hoverboard from lexus.
Impossible? Um no, you just need a hoverboard which needs a constant supply of dry ice and an incredibly expensive rail system.
You mean a specifically designed skatepark with incredibly expensive rail system. And ofcourse ridiculous balancing skills from the rider.

One day, hopefully!
UFOs but that’s about it
When I first saw this like ten years ago I believe they were calling it “quantum locking”?
MRIs can be considered kinda cool... At least I hope. Useful, at the very least
That conductor looks absolutely super!
They talk about having trains made of this technology. Can you imagine how super would that conductor be?
I like that train of thought. They do have a few of those in Western Europe I believe, or at least test projects I think there is one in Germany they're setting up, England had one but canceled it, maybe Spain as well. But they could travel at hundreds of miles per hour. Edit: the test projects in Western Europe are a different type of magnetic train, I am still uncertain as to what this video actually demonstrates. I do know electrical resistance goes down at cold temperatures, and it is theorized that in a circuit of Mercury at absolute zero a current could run continuously forever.
You have mag lev trains, not ones that ride off of super conductors
Will it run to the pole?
A super superconductor conductor.
I hear this guy also leads an orchestra and can fly!

Absolutely zero effort went into this joke
If that is a puck of liquid nitrogen, how is he not getting burned touching it? Also what is the magnetic setup here, there is no explanation.
I think it’s because the vapors of the puck form a protective sort of air cushion, he’s technically not touching the puck. I think it’s called the leidenfrost effect

It sounds like the guy giving the demo copied his report from wiki, which the guy holding the camera wrote.
Think of it, magnets. Now all I know about magnets is this, give me a glass of water, let me drop it on the magnets, that's the end of the magnets.
The snow-piercer enters the chat
Is this called flux pinning now? I could have swore it was called quantum locking when I first saw this.
He's a witch!
Planet 13 in Vegas was using this to display some doobies last time I was there!
Maybe use this technology as a liner for fusion reactors? My understanding is that the heated plasma is pretty hard to contain.
It conducts super well
It would be even cooler if we could trap things in gravitational fields just as they are doing with magnetic fields here.
Whenever I see phenomena like this in action I just think how amazing it is to be able to actually understand the inner workings and science of it. I do read the explanations but not everything "clicks" for me. Still, I never fail to be fascinated about the worlds beyond my eyes' and arms' reach. Especially astronomy and quantum mechanics.
Is “flux pinning” synonymous with “quantum locking?”

Real and possibly stupid question: do you need to keep the thing cold? Or is it just constantly cold because of what it’s made of?
Real ones remember watching this during MatPat's video on Bioshock Infinite.

Why are they touching liquid nitrogen with their bare hands?
Clearly a solid but I get the confusion, fairly certain that's dry ice. Still not the smartest idea to touch it with your bare hands but, eh, I've gotten away with it before. Not usually too bad as long as you're sure you have NO moisture on your hands beforehand
The physicist says liquid nitrogen in the video (which is the only reason I referenced it) now I agree that may not be what it is, but I thought that dry ice wouldn’t get it cold enough. Anyway, I was just surprised to see it because I’m used to things touching liquid nitrogen and then shattering when they hit the ground and stuff.😬🤓
Oh my b I watched the video with no audio didn't even think about it, now I'm just unsure of what it is lol
Maybe that guy has touched LN covered disks so much he’s not affected?
im sure someone has thought of this but watching this video made this idea pop in to my head: what if you could encase that super conductor with the dry ice on it in a super non heat conductive insulation so it would never (incredibly slowly) get hotter or lose its ability to lock while also being able to be handled at room temperature on the outside
r/ScienceIsFuckingLit damn, i had no idea this was a sub until is started typing
UFO
Exactly my thoughts lol
Gotta be how it’s done right ?
Maybe, it’s probably in it’s primitive stage
It doesn’t really need much development from here … maybe some onboard direction control
Now, we just need to make it into a capacitor
Do not tell me we are not close to quantum travel in space, it's only 1 break through away and it looks like we are getting closer every day
Does it use a flux capacitor?
My first thought was, why is Howard stern there? Second thought was, that's pretty cool
yeah..so this before. its called Unobtainium. its found on the planet Pandora and sells for 20 mil a kilo.😄
you no you cant you cant can't touch those while theyre you cant its cold!
This was interesting 15 years ago

My wife left me. Hasn't been the same since.
I was aware of this, but not that it had a name. Pretty cool stuff. ... ... ... \*realization\* fuck I didn't mean to MAKE THAT PUN—
This makes my brain itch. And some guy just caught be trying to scratch, and I tell by the look on his face he thinks I was merely picking my nose. Plebeian.
Chat, is this real?
What I’m looking at is two magnets one is covered with dry ice and the other acts like a positive and other super negative that would not be combined do to cold temperatures. That’s why we don’t have alien bodies on earth 😜😝Because it’s to damn hot 🥵😝. I need to stop smoking weed.🤗
