The Lexus Hoverboard - It's Real!
Many superconductor elevation stunts like it have been around Youtube for a while. However; this is being portrayed as a novel idea, which it is not, and a similar hoverboard has 0% chance of being practical considering superconduction is a major ingredient in the recipe. Nevertheless, great PR video!

World Record 100 Tesla Magnetic Field Created -w/eerie sound

So, what can you use this for now?

A 100 Tesla non-destructive magnet has a major effect on a wide range of science. It's a one-of-a-kind tool for studying the fundamental properties of materials, from metals and superconductors, to semiconductors and insulators.
Icy achoo dither.

The Vanishing El (NYC)
I love this. Damn, I'm convinced that as a species we've made and continue to make a huge mistake in terms of technology in that our only aim is to improve efficiency. There's another far more important factor for me, something that could be called for lack of an official term: the dog-head-out-of-window co-efficient or in other words: how much does this technology contribute to my joy of being alive.
I'd choose a ride on the "EL" over a nasty taxi or subway ride any day. Maybe someday when superconductors are refined enough we'll see the return of scenic travel in the big cities.

Quantum Racetrack Explained!
Just have the magnet under the track moving along with the superconductor-racecar locked in place above it. EZ.
Real Quantum Levitation on a Wipe'Out Track
I just briefly read about it. Essentially below certain temperatures superconductors cannot have a magnetic field inside its body (I still don't know why), so the magnetic field flows "around" the superconductor, looking kind of like what air looks like going over an airplane wing. That seems oversimplified, but I'm dumb and I haven't taken E&M in 2 years...>> ^MycroftHomlz:
^jealous.
@rottenseed, It is the Meissner effect. I can go into it... are you sure you want that?
Controlled Quantum Levitation on a Wipe'Out Track
Well... Their diagram is a little funny. I think you could do it if the car or track was a superconductor, but I don't see the reason to make both superconducting.
Superconductors levitate by generating an equal and opposite magnetic field outside the superconductor to expel the magnetic flux inside (think Lenz's Law). The Meissner Effect is naively perfect diamagnetism.
I look at this and think it is totally doable. If you want I can send the video to guy I know that studies superconductors. I think most physicists would probably say that you could make this.
>> ^dannym3141:
Pretty sure that's possible, i don't care to speculate how in an engineering fashion, but sure, you can get them to follow a track and even suspend them upside down if you like, i don't how well they can stick to the track during fast turns, perhaps you'd need to tilt the surface gradually.
I assume it'd be easier to cool the track rather than the cars, otherwise you're gonna have to wire up the cars to deliver coolant which would destroy the point. The idea of nitrogen gas coming out of the tiny cars for the whole video is a bit of a suggestion it's not real. That's assuming he was putting nitrogen in the car in that weird pipe.
Shit, they do stuff similar to this with trains full of people in some places. Probably a bit of a tamer ride because of the much higher masses involved.
(I study physics, but maybe someone knows more than me about the current progress on all that)
Quantum Levitation
There's nothing "quantum" about this!!!!
Stop falling for their marketing bullshit hype!
Superconductor levitation have been known for a very long time.

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??
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.

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.

Your playing with powers you can't possibly understand, life finds a way.
Yeah, raptor-riding jesus does not approve of this evil magicks!
I take it you didn't get the Jurassic Park reference, because that is the Ian Malcolm actor's voice.
It's ok, on second viewing, I don't think it is him anyway. I <3 magnates
All hail the superconductor raptor.

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

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