That is so incredibly wicked awesome. Thank you again, science.

Supercool

Curses! You beat me to posting about this by an hour. This video has a shorter presentation, but for a slightly longer one with a bit of an explanation and one more cool trick not shown here (and classical music!) check this one out.

Beat me by 8 minutes. Is your video really too similar to be another sift?

Quantum locking...how does that work?

I'm going to say two words that are probably overused but are perfectly suited for this situation.

Holy shit....

Alright, this is unbelievably fucking cool.

You guys might (not) remember the Meissner effect I posted earlier (http://videosift.com/video/The-Meissner-Effect-Awsome-physics) This is exactly the same effect.

The fundamental difference is that the superconductor in my vid is thicker than in this case. In this case, a 1 micron YBCO layer is deposited onto a sapphire wafer (probably through physical vapor deposition [http://www.youtube.com/watch?v=_a9Slv1T1UM, go to 3:15 if you want to skip to PVD])

When you deposit a thin film with PVD you will inevitably form small imperfections at the grain boundaries in the film, usually only nanometers wide. When brought down below the superconductive transition temperature (IE, liquid nitrogen temp), the magnetic field lines are able to penetrate these grain boundaries in discrete quantities (unlike the thicker superconductor) forming what they seem to be calling "quantum tubes". The superconductor pins the field lines into these quantum sized tubes, and the force required to distort the field lines is greater than the weight of the superconductor.

Read this for a bit more: http://www.quantumlevitation.com/levitation/The_physics.html, but it doesn't seem terribly well translated, and it cant seem to decide how layman's terms it wants to be.

Is he being interviewed by Harry Shearer?

I didn't think that PVD would form YBCO.
I could easily be wrong though--my knowledge is out of date.

Great video about the Meissner Effect.

I had no idea Jeff Goldblum was so interested in superconductors.

One word: Speedtrain

*Quality.



My mouth was hanging open the whole time.
These things need the sound effect of the flying turrets from BioShock when they move.

Physical vapor deposition (evaporation) pretty much works with any material that can be evaporated in a vaccuum without decomposing. Metals, semi-metals, and many ceramics and metal-oxides are candidates.

It's neat but that thing would totally freeze your nuts for all the uses I can see.

How much load can be exerted on a mass that is 'locked' in place like that?

i.e. Could this be a way to make super sweet hover bikes and cars a reality??

Comment hidden because you are ignoring dag.(show it anyway)

That's a key question. Also how cold do you have to keep that superconductor? What about room temperature ones. Weren't they all the rage a while back?>> ^BoneyD:

That is genuinely amazing. I love science like this. Incredible.

Your playing with powers you can't possibly understand, life finds a way.

And when that baby hits 88 mph...you're gonna see some serious shit...

Room temperature superconductors are not a reality yet, at lest not for longer than a couple of nanoseconds at a time.

Guess I'll need to move closer to work then.

I take it you didn't get the Jurassic Park reference, because that is the Ian Malcolm actor's voice.

Aww crap, I should've read all the comments before downvoting yours (damn me and my lack of pop culture!).

That being said, now the raptor-jesus reference is all the funnier.

It's ok, on second viewing, I don't think it is him anyway. I <3 magnates
All hail the superconductor raptor.

@MycroftHomlz heeeeeeeeeeeeeeeeelp...howz them works?

Quantum locked? Don't blink.

SPACE ELEVATOR.

Can this technology be used to transport quantummushroom

>> ^deathcow:

Yes and no.

Favorite moment for a science noob like me? When the guy corrects the interviewer IMMEDIATELY. "It's not floating, it's locked."

Love it.

For the disk going around the ring they should add a small orifice or pipette as a nozzle for the evaporating nitrogen to propel the disk around the ring to make a rocket hoover UFO. Otherwise, it all boils out of the top.

That is astoundingly awesome.

For the demonstration, not much imo. The guy had no difficulty adjust the 'locked' item with his hand, which can't be exerting a terrible amount of force.

Scaling up in size is another matter (and totally outside my area of simple deductive logic ; ), I would imagine as your super conductor blocks get bigger you could indeed support much higher weights.

It's interesting though, I wonder how a train, for example, would go around corners? Would the track need to be curved, as the superconductor is locked in a certain aspect to the track ie. like a toboggan? At the serious speeds an air friction only train could travel at, not tilting in to relative shallow corners might cause some serious in cabin 'passenger migration' issues if the train didn't lean in to the corner. *grin*

But yeah, that is some cool (no bad pun intended) shit right there.

I. What. Whoa. That is rather neat and I. Wow

>> ^deathcow:

Ahhh... I KNEW rule 34 would apply somehow...

Any vehicle or contraption that operates purely on "Hover" has n o way of stopping without friction.
Back to the drawing board for Super Trains. How could you stop a 250 MPH train ?

You can always push back on EM fields with other EM fields, right? Perhaps with even greater force than that of friction, as EM fields can scale perhaps better than materials can absorb heat (without melting), I would wager.

WHAT THE WHAT WITH THE WHAT!?

Looks like a quantum mushroom cap.
