Magic. Got it.

I still maintain that this is Owen Wilson's long lost twin or something.

He just has *that farking look*.

Don't bother. It's just a bunch of scientists lying. It's making me pissed.

Hover car, here we come.

Honest Bender: Don't bother. It's just a bunch of scientists lying. It's making me pissed.

So it's related to string theory?

That's levitation homes.

Superconducting at room temp would be awesome.

/some material of course, not me!

Jeez, that was a wall of text. All they had to say was that it is the ICP effect.

HOLY SHIAT!

Someone needs to create a bot that scans all Fark articles and posts the Oblig images. Ya know automation and stuff.

The Institute for Quantum Computing (new window) has been doing that for years.

From the link on the 20 degree C superconductor: "This discovery is being released into the public domain without patent protection in order to encourage additional research."

Suck it, patent trolls.

Mixolydian Master: So it's done with supercooling things. I thought such a thing from seeing the fog coming off the frozen disc. If it's chilled to the point of superconductivity, then how is the guy handling it with his bare hands?

Contrary to what you see on TV, touching something that cold won't instantly freeze your hand off. He is pulling the disc out with tweezers though.

Not exactly the same thing, but this video shows why you can handle something like liquid nitrogen for short periods of time.

So, like a photo-Bevets?

I want this for my refrigerator.

I thought they debunked the video as fake.

^ No, the video is in fact, real. As is the science, and the explanation.

Let's face it; you knew it was a matter of weeks. (new window)

Hopefully comparing the videos make it clearer, to some of the people from the previous thread, how the newer stuff differs from the old spinning magnet demonstrations.

OK, that's about what I figured was happening. Not so much "quantum" as "superconductor" levitation. The superconductor can't maintain an internal induced current like a regular conductor can because that would quickly lead to infinite current. Instead, it exactly reflects the magnetic field. It's neat and all, but I don't get where they're claiming a quantum effect.

Their explanation

Apparently it has to do with the fact that they're use an extremely thin superconductor, which allows magnetic field lines to group together and penetrate the superconductor via discrete, separated channels. That way the superconductor isn't just repelled -- it also gets locked into place in a configuration (relative to the magnet) that resists alteration.
