- www.ted.com How can a super-thin, three-inch disk levitate something 70,000 times its own weight? In a riveting, futuristic demonstration, Boaz Almog shows how a phenomenon known as quantum locking allows a superconductor disk to float over a magnetic rail -- completely frictionlessly and with zero energy loss.

Anti grav racing is just around the corner...
Wipeout will soon be a reality!
Who is paying for billions of dollars of sapphire and steel?
Same as who is paying for steel and carbon right now. Us.
I'd be a HUGE jump in taxes if we want any of this built, and nobody wants that.
Cute trick, but obviously this has little to do with anti-gravity... if it did it would float wherever you put it. Gravity is a whole nother force. It is the fabric of the universe.
yeah, sci-fi will not be fiction anymore
Well thats arguably the coolest thing ive seen on TED for a long while. The potential applications for this are amazing, even to my limited brain
***** I always like the vids you comment on, this was fascinating, thanks for leading me to it.
Let's think about QLock trains or QLock industrial elevators
or even better, QLock Highways, I'm just waiting for the time we could make "Syncron Batteries" capacitators tha would be Syncronized in an flux frequency avaliable kilometers from the towers, so everything would be energized just as much as it needs with no cables
@@MrNatmax - Really dude? You're just going to try and get credit for Nikola Tesla's work on the www? Good luck with that.
@@blackopal3138 the point was to make someone remember that Nikola Tesla already had this Idea
but we just don't have this becauso none have helped him
@@blackopal3138 We are just rediscovering what he did and thinking about what could we do with that, like he did
This is videoed in 2012, why I just found there’s such a cool thing as Quantum Locking in 2019 and never heard about it before?!
Because it proves thw flat earth and hiw the sun and moon actuall y work
yea wtf.. governments are refusing real life stuff from it?
Tim Thomson either you’re a troll or just uneducated.
Look up Lexus hover board. They made a hover board that works on this same principle.
@@hankyboy42594 or both
I love TEDtalks. I am so gratefull for this youtube channel. Thanks and respect to all the people who make it happen. From the staff to the talkers.
The super conductor slowly heats up and begins to loose its properties. It is this change of state that accounts for the slowing you witnessed. And yes, air resistance is part of the answer. There are several variables involved.
So where is my hoverboard?
I think they're gonna need to make a hover board trail specifically :o BUY ME ONE!
Derek Leung as soon as the sidewalks and streets are constructed of magnets
Joshua Meadows The earth is a giant magnet.
WAIT! HOW DO WE BRAKE!? We're gonna need to manual stop with friction on the ground or something of that sort right? o.o
Sonlang Siek To break, add heat to the hover board for it to lose its superconductor properties?
much science, so light
wow
many quantum
Such floaty magnet
Me Tarzan, you magnet
LK-99 says hello
For me, this "quantum locking, not levitation" thing, perfectly explains how UAP's move about.
F-ZERO WAS THE GAME!!! Great video
7:45 That was not the first time this has been demonstrated, he did that a year ago already. But those attendees don't visit RUclips of course.
He could speak at an Apple iPad keynote. Same rhetoric, same dramatic pauses. It's magical.
Can’t believe this hasn’t been patched yet
What did you mean by this ?
@@morgansmart1265 obvious. Because we all know the world is a simulation this should have been patched. A glitch in the matrix.
@@TheYCrafter lol definitely a glitch in the matrix, this technology is on the verge of serious applications 😁
That's a brother speaking LOL
Feels good to finally understand how the turtle on which the Earth sits is lifted.
WE'RE SO BACK
Have to wait another hundred years to have some practical and economic application!
yoppindia the magnets in MRI machines are generated by superconductors
They're clapping at the demonstration of these phenomena. Like Boaz says, superconductivity has been known for 100 years. We haven't been able to demonstrate them until recently.
This is absolutely amazing !!!
Could you swap out the neodymium magnets with electromagnets? And then maybe swap that out for polarized vacuum? Even possible? How many years away?
Is this good for High end GPU in PC
you mean liquid nitrogen cooling? yes ofc
D-Wave Quantum Micro Processor
Now to find an efficient way to keep all these superconductors chilled...
Could this be used for moving things? I'm sure there's much more incredible uses for this, but the first thing I thought of was putting a superconductor under my sofa and moving it with remote control to my new flat.
The superconductor has to stay cold because the metal's energy has to be low so the electrons within fall to their lowest energy state. This allows the material to form what you call a Cooper Pair. This pair is consisted of two electrons that propel each other throughout the material with no resistance.
When the superconductor is put on the rail, the magnetic field of the rail creates surface currents that produce an equal and opposite magnetic field. Hence levitation.
Make F-Zero and Wipe out happen; we have the technology.
Air resistance and the loss of superconductivity from the material heating up as it's exposed to room temperature air.
If you keep it in a vacuum and keep the temperature below critical, it would remain frictionless.
thank you sir. you have just proved how ufo's fly. amazing
That was my intent ;-)
Look the article in Wikipedia about the superconductivity. As far as I remember from school, this effect appears on extremely low temperatures (about 4..77K), so the conductor has to be frozen down by the liquid helium or nitrogen. There is a certain boundary (look at the graph in the beginning) when the common conductor (joking, it's a special fusion) becomes a superconductor. So as the cold plate heats, the boundary is exceeded, and it not a superconductor anymore, so it stops flying and fall.
so if it can carry so much weight, why is he able to change its position in the magnetic field with so little effort?
Yeah ok, that makes Sense ^^
Robin Wersich - like a magnet buddy! it's easier to navigate away from its force rather than against it, I often get the impression people are so skeptical about everything. is this a cool trend?
teresa Garcia I don't really get your point...
But Jwaxenbaum602 already made it clear for me
@@robinwersich3424 - her point is that she is better than you. peace
Oh I was talking about the thicker disk, not the .5 micron one, but I guess it's probably the same disk with something around it.
Anyway thanks for the feedback.
I wonder if anyone has made a foil nacelle pressure chamber to contain and exhaust that gas.
Yeah, Geordi Laforge…. but his work was stolen by the Romulans and they had him eliminated, so the only existing one is on Romulus.
Sorry, what gas?
I was thoroughly impressed by the transcription that Google Captions gave in this video
There is no such term as "quantum locking". It is known in all superconductivity books and papers as flux pinning, which occurs in only Type II superconductors.
Old patch
I don't think any of this is new at all, but it is fascinating.
Bioshock infinite brought me here
What's more important is what will it take to make you leave 😮 … 😂 I jest... self-entertainment therapy... peace
This is absolutely amazing. From a mechanical engineering stand point my head started into application mode. How to keep the conductors cold, and what could be achieved!!.
Does anyone else suddenly have the urge to play F-Zero GX?
Rimmer Dall YES 👍
Nahh more like Bioshock Infinite
listen closely. He says that superconductors have a distinct characteristic of repelling magnetic fields and goes on to say that, though they do in fact repel said fields, they do no do so perfectly and indefinitely. There are some strands of flux that get through into the superconductor and it is when you introduce the superconductor into a large magnetic field that it locks up these strands of flux that get through it thereby entering a state of Quantum Locking or Quantum "Levitation".
Does the pinned superconductor and the load attached to it add to the weight of the magnetic base it's pinned to? If I use a disc to pin a car to a magnet like you described, would I be able to lift the magnet with the car as if I were only lifting the magnet, or would it be just as strenuous as lifting the car with it? Does the superconductor pin directly to the magnet, or to the space around itself and only move with the magnet in response to changes in space?
Jane Doe Now that is a REAL question, worthy of such topic. I'd really like to know the answer to this as well. If the superconductor does not add its weight to the magnet beneath... oh, the possibilities....
Jane Doe A bit late perhaps, but no. If you want to accelerate mass you need the necessary amount of energy. lifting the magnet would include lifting the car. Just like lifting a rope includes lifting whatever it is attached to.
Except that a rope doesn't obey to the same laws of physics. He said that it was not a repulsion, but a quantum locking, to me it mean that the magnet doesn't support any weight at all, everything is supported by the supraconductor x magnetic field.
So it could be possible yet it seems unlikely.
Le Cobra No. It isn't possible. If you want to accelerate something, you need to use energy to do it.
It would act like a zero friction suspension that you can use to move along the rail. The rail would have the weight of the car pushing down on the magnetic suspension, by the car would stay locked in the air. The car would still have friction due to air resistance, but it would make it easier to move. Because it doesn’t require friction with the ground, so it would stay in motion with less force. He could not literally hold the car in his hand because the weight has to go somewhere, but he could push the car along if it was on a magnetic rail system.
I've never seen it demonstrated. strange considering how impressive it looks.
it can levitate a small car?...THEN SHOW US THAT.
hey hes showing you the possibilities of the technology this shiz is amazing
+There is no death. How about you show us? Take the responsibility in your own hands before you ask another? If you are not interested, maybe you can do some research and at least show us how its possible? I would show, but people never try to answer the questions themselves. Rather just bark
Charles B. Sharpe
He made the claim that he can levitate a small car, not me, so he should hold up to his claim. That's my point.
if you want to see this tech in real life look at Coral Gables castle in Flordia the oil cartels are shelfing this stuff dude Bozag couldn't even if he could and wanted to show your small pea brained nous
mikewahby
coral castle is made of light weight rock he didnt need to use levitation
yes, no, and no. I know you only asked one question but its actually a really good question and a complicated one at that. simply put, in a perfect world, yes it would go on forever, but friction with the air around it would slow it down. Also the reason the material he's using is a superconductor is because its cooled below a very very specific temperature. this means that as it spins and heats up, it stops being a superconductor. the third no was because when he mentioned the lack of friction
finally i know how the pyramids were built in these times thnx^^
Bang! Missing piece of the puzzle, eh? Good on you, I hope I can figure it all out one day too!
It makes me immediately wonder about the magnetic field of the Earth and how it "dips in" at the North and South Poles which are the coldest points of course.
Has anyone tried mixing this type of levitation with gyroscopic procession? Maybe this is how ufos move sideways while repulsive against earth's magnetism.
You overestimate the earth's magnetic strength. If anything had enough power to push against the magnetic core, it would collapse it in the process. The earth's core is molten, thus in a liquid state, it's magnetic direction can move around quite easily, especially if something had enough power to push against it. Newtons third law prevents something like this from existing, maybe if the earth's core wasn't in a liquid state, but even then, a silly idea to be honest.
I think the most difficult part of having a quantum locked ufo, is to keep it at a low temperature required for the superconductivity state to stay. maybe some alien did it, maybe not.
I love our interactions David. I had a friend who thought consciousness was a fundamental part of the universe, but I thought it was an emergent phenomenon. We had a wonderful interaction. I'm sure you will agree that disagreeing can be very agreeable for those intrested in exploring the truth. It is through the interchange of opposing ideas where we grow and learn the most. I have learned much from you, and I have changed some of my positions as a result.
No one has a monopoly on the truth.
Would it be possible to use the magnetic field of the Earth for flying saucers ? Could a bigger conducter ( e.g. 3 Meter) be used for transportion into space for everyone ? At least like the flying cars in the movie: "The Fifth Element" :) Or is the magentic field of the Earth to weak ? Thank you for your amazing speech !
Now that's using your noggin,lol, love the flying saucer question.... But the magnetic field is out in space. It cannot be accessed on the surface or even from the atmosphere. peace
@@blackopal3138 The Earth's magnetic field can absolutely be used on its surface. Just look at a compass.
The problem is just that it's not that strong.
@@Max_G4 lol, i'm a little surprised that I answered that so definitively, like I would know. Compass is a compelling example. In effect we already have the proof of concept, we just have to start increasing the load capacity. Look at LED 100 yrs later. Never know, pretty cool. peace
It is possible to adjust it with just a little push, but u need a *lot* of force to push it all the way down into contact with the magnet rail.
My name is Jeff
Hi Jeff.
It can be locked at any height. The electromagnetic field lines spread out away from the magnets, so there's a maximum distance where the locking effect can only just counteract the superconductor's weight.
The sun is a super conductor circling above our Flat Earth☝😄
are you serious or am i just getting wooooshed here?
Flat earthers watch ted!
The superconductor in that locked state is in so much pain that it cannot move. In fact, it doesn't even want to move. :)
what we need is a 5 mm thick piece of superconductor, inside of its own refrigeration unit keeping that superconductor superconductive and expel the heat it produces to move forward or slow down. now, as he said that a 3 mm thick piece can pick up a car, its vertical location is locked to the magnet but its horizontal location is free, to get it set to a certain height you must hold it at the desired height and then turn on a electric magnet beneath it. as the superconductor has no resistance from friction but gravity is still in play. i would suggest that there be a way to slow down through means of the mag rail. put small buffers of magnets with reversed polarity to slow it down, with small thrusters for acceleration and deceleration.
So... did you copy that comment from the conversation you were in, or vice-versa?
i dont understand your comment.
If you are using a magnetic rail, you could probably propel and break it by using a magnetic pulse sequence like some trains do. It works like a snake flexing ribs in sequence to slither. Yes, I agree with the idea to have a compressor of some type to cool the duper super conducting component but I guess, you'd just have to be careful that the materials used on tye shell wouldn't interfere with the magnetic fluxors in the first place.
WTF!? Nothing new - for 100 years now. Go to your nearest University and listen to a course about superconductivity. The reaction of the audience is kinda ridiculous
i believe the disc is made of ceramic compound and by cooling with liquid nitrogen it releases a magnetic field when the atoms react to the rise back to room temprature. i would like to see a similar experiment where the disc is heated with lasers, curious to see if it would be more reactive under controlled temp.
I am from Sudan and a fan of your useful contents. Thank you
Superconductors are strong antiferromagnetic substances that will expel external magnetic field that coined as Meissner effect. Since superconductors are enveloped with strong antiferromagnetic field in which this will help stationary electrons from amassing photons from surroundings. Again this doesn't mean that superconductors have zero resistance. It's just that free electrons that have dissipated out their stationary photons are allowed to re-amass stationary photons again from surroundings due to the presence of strong antiferromagnetic field of the superconductors themselves. Superconductors have quantum locking above an external magnetic field because it's a strong antiferromagnetic field (similar magnetic fields) that repel the external magnetic field to allow it to float above the external magnetic whereas its opposite magnetic fields to the external magnetic field will make it attracted to the external magnetic field that caused it to be locked literally to the external magnetic field. All superconductive substances at characteristic critical temperature will turn into a superconductor with very high specific heat capacity. This prompts us to suspect that stationary photons may play an important role in fostering superconductivity condition. At least we know now that missing link between electricity and magnetism is the photons in which free electrons are enveloped with stronger magnetic field due to the presence of abundant stationary photons onto themselves. Thus, we strongly believe that abundant stationary photons present on nuclei of superconductive atoms may foster the creation of strong antiferromagnetic field within the superconductor itself. If you are interested in real discoveries, I would recommend you to read my book, The Unification Theory - Volume One and you will be amazed with lots of new, interesting discoveries. In God I trust.
If you are interested in discoveries check out IISc Bangalore's researchers that made type 2 room temperature superconductors at atmospheric pressure and 13 deg celsius critical temperature by using a gold silver nano composite. See what I did there.. Also u missed the opportunity to say the missing link between electricity and magnetism is electromagnetic waves. Lol. Also ur book sounds like the ambitions of CCP. The Unification theory.😂😂 I am sorry I had to say it. Also no hate.. I just googled u r from Malaysia. And ur book is way off my level I think. I am 17 and Indian and just know basics of magnetism, superconductivity .etc and why it happens and how to calculate some things about it. Will I understand it? I will read the whole book if u say yes. but please say truly
Space Elevators. Come hire me to design it. Win or fail, give me that job.
I find it a bit funny that you are taking the setup of his demo so literally. The force slowing the disk down is called 'air resistance' or 'drag'. When he says 'frictionless motion' he simply means that there is an absence of mechanical friction (since the magnet and the disk are not touching), and that the quantum locking effect is making a negligible or nonexistent contribution (depending on the instantaneous temperature of the disk) to the dissipation of energy you are witnessing.
that is the coolest thing ive seen so far.
Somewhere, there is a Cedar Point engineer wetting his trousers just thinking about the possibilities!
This is the way to go for future transportation.
New high-temperature superconductors can be cooled with liquid nitrogen. That's still below our fridges (well, mine at least, dunno about your's), but it's less expensive to maintain than with liquid Helium.
We do they are used as huge storage rings like the SC super collider except no collision, we did this for texas in the late 89 early 1990's. It is not normal public knowledge-yet not classified.
In quantum locking, the superconductor is not really "hovering", but locked into place. If you have a superconductor "floating" above a magnet, you can flip the magnet over and the superconductor will follow. With the superconductor under the magnet, it seems the magnet is pulling it instead of repelling it.
If you've ever played Bioshock infinite, this is how the city floats.
He redefined the word 'awesome'.
Actually it gives off a mist because its sublimating (changing from solid to gas, skipping the liquid phase due to high, or relatively high, temperature)
He is going to flare up when he sees Boaz Almog "LEVITATES"
Excellent discription👍👏👏👏
He spoke about the potential applications rather than the fundamental research that must take place in order to raise the critical temperature of superconductors. Superconductivity is a very old phenomenon, known to many of us, but it is not yet practical and the technology is not yet mature except for very demanding applications, namely NMRI.
I would have appreciated if he had shown a graph of the advances in superconductor technology and how far we have yet to go.
You and how many more? I have seen several videos of the phenomenum but not a single one explaing it, until this one. That is what TEDs is about, talking about ideas worth sharing...
Thank you for this video. I really enjoyed it despite the fact that as a student I preferred my chemistry classes rather than my physics class.
My first sentence does not make any sense ^^ . "Read over before posting", I need to carve this somewhere on my body. "... superconductor requires a low temperature like boiling water requires a hot temperature." ... this comparison does not work. Water is a material, "superconductive" and "boiling" are characteristics (you can find some other fluid that boils at low temperatures)... Therefore, I had to add "I believe we won’t find any material ... "
Each plate interacts with the magnetic field, basically changing it so that when it reaches the inner plates, it wouldn't have the same effect
If you've been searching on RUclips before you'll not be surprised with this...but still THUMBS UP! I never dislike a video like this...
Jealous? I'm a child of the 80's and growing up I loved to watch the science shows for kids and one of the cool tricks that they always would show was magnets and levitating items with them. I just wondered how most of that audience had never seen those sorts of images before -- I thought that they were common place.
so that's why aliens have disc shaped ships
What you see is in this video is called Meissner effect and was discovered before world war 2 by Walther Meissner and Robert Ochsenfeld.
It was also used in some commercial solutions like promoting nike shoes (just google for "nike levitation shoes" in the videos).
Anyone after LK-99
unless you are in the vacuum of space there will always be friction, wind resistance is one of the hardest frictions to over come hence all the scientific and engineering programs focusing on aerospace.
É realmente impressionante, mas tem uma limitação curtíssima de tempo. O disco precisa ser mantido em uma temperatura baixíssima, e esse é o desafio.
My only questions are why did he use such a thin superconductor, and why didn't he demonstrate its load-bearing capabilities? He leaves a few crucial things out of his explanations.
So this is how Aliens come to Earth... Silent, Fast and without any trace...
Why have I only heard of this recently?! Why is this not global news?!
Liquid nitorgen is at 196 degrees C and the coldness of space is -273 degrees C so it could be used in space
So the catch is keeping it chilled, I guess?
The magnets purpose is to supply the magnetic field that permits the quantum locking. Cooling it wouldn't really do much of anything to support the superconductivity.
I think that would put a damper on the situation.
Wait so you can use a superconductor like a battery to store massive amounts of energy, then use it for (next to) zero friction propulsion that can hold massive amounts of weight... Wouldn't that be the ultimate vehicle?
how could you possibly dislike this?
holy crap. HALF A MICRON?!?!?! how does he not get cut holding it with his bare hands???
They clap and give a standing ovation to Superconductivity and Quantum Levitation? This isn't an earth-shattering idea here folks, we've known about this stuff for years... o.O
5:54 I find it a bit funny that he asserts "frictionless motion" while giving it a new push every other second.
This amazing discovery is finally on TED!!!
0:22 Talk about old hate. That was discovered in 1911.
That is absolutely incredible
its not steam, nitrogen would give out nitrogen on boiling which is invisible. Mist is actually very small particles of ice that are formed through condensation of water vapor that is present in the air. And because temperature is so low near the surface of liquid N2 that instead of water droplets, we have ice particles.
Holding a car in my hand?.....
Man I better join the avengers or the justice league I guess...
aww man I wanted to see a demonstration in holding weight.
