Quantum Levitation

[Murley]

This is some really impressive progress towards finally getting hoverboards.



Yeah, I guess there may be some other more practical uses for it as well. Keeping the thing cool is the mission...

[OptiC]

Of course there are more practical uses... Hover bikes

Pretty awesome demo! Cheers for posting it up.

[Captain Starfish]

Wow - could be used for a really cool monorail

[Murley]

I don't know how these magnet things work. Obviously we need to keep the superconductor cold - if we were to encase it in a cooling device, would it still levitate over something outside the cooling device? Maybe internal cooling is the answer but either way it's a whole lot of extra weight :/

[Captain Starfish]

Also note how easily the thing can be moved in attitude and distance from the magnets. Cool, yes. Practical, not so much.

[Murley]

Good point but if they can control minimum separation distance, hover board. BRB, saving pennies.

... got a bit too excited to be able to make words for a moment there. Holy shit, that's awesome.

Super excited to see what this can do for long distance rail.

At the super cold level, strange stuff happens.. I've seen liquids pour through materials that would normally be impossible.

We know nothing!

awesome!!!!!!

Y'know someone will eventually micronise the cooling apparatus, and next we'll have ultra-gay 5000 superconductor rollerblades.

I just want some grav unit that can hold up a jet engine strapped to an aerodynamic frame thanks. Wipeout League here I come.

From what little I have divined from this, the Meissner effect is one of those bizarre quantum force effects that no-one can actually explain and yet can now be so entertainingly demonstrated. Wiki diagram to illustrate...

Correct me if I am wrong, the magnetic field no longer penetrates the material, but is warped along the surface like a bubble..... How many other forces can perhaps be affected this way?

PS: when someone starts spouting comments like "Quantum levitation" and then demonstrates it on an atomic (ie, real world) model, then the implications become quite profound. I want highways of rare earth magnets that I can fly along wearing my suite woven of fibres in their superconductive transition state (solar powered of course, otherwise inductive). No need for hover boards or bikes at all

It was explained to me that the Meissner effect was essentially the Bernoulli principle on a different medium.
Much like your illustrations Skut.

People have been playing games with quantum level physics on an atomic or macro level for a long time, seeing a real world experiment demonstrating the application is encouraging..... I mean, the whole object behaving within the field, simply by reducing temperature to the superconducting transition state.... wow! (ok, I am new to to this, but WOW)

[Edog]

That is awesome, amazing that it works upside down too.

This was my desktop for ages a few years ago.

Hmmm, if we could actually see the subatomic quantum foam of reality (in a supposed vacuum) then I guess we would all go insane!

[Desmo]

Quantum foam makes me roam.

I found an excerpt of the documentary where they try to reach absolute 0°, some strange stuff happens in this quantum region (Is quantum even a correct term for these phenomena?)
