If that is as real as it looks, it is incredible.

Quantam Levitation, the transport of the future?

What do you mean with "future"? ;)

I shot this one last week? :lol:

But while ever it requires liquid nitrogen types of temperatures to make it work, it's not going to be a practical method of levitating very much.
But it's cool factor is through the roof ! ! ! !

Mag lev is a pretty different technology to this one as it requires very precise control of the distance from the magnets. This tech as demonstrated allowed the item to be varied in distance and maintain the effect a lot better than in the Maglev system. Pretty sure the maglev system wouldn't work upside down either. But I've been wrong once before, so I guess it could happen again.

I too was very skeptical of the maglev, but it happened. I tried building my own meglev for my school project when when i was 12 and it was so bad. LoL.

I'm no physicist so i'm not too sure how different it is theoretically. But to my layman understanding it seems to have a similar concept. Meglevs needs cooling via nitrogen as well and requires a superconducting material and magnets, so does the quantum levitation.




"Suspending a superconducting disc above or below a set of permanent magnets. The magnetic field is locked inside the superconductor ; a phenomenon called 'Quantum Trapping'."
What ever that means. LoL.

As soon as they invent a super-conductor that works at room temperature, we'll be able to push around huge weights with little, or no effort at all.

They have a mag-lev train in Shanghai that does around 500km/h, in complete silence and smoothness.
Wish I could say that about our trains!

And then there's the need for a "track" of sorts. Hmm! But sooo interesting.

(Benny, been on it. And, yes. But there was that one that crashed recently. And then a phew weeks ago I was on the new metro train in Torino. I was right up at the front "windscreen" watching the (well-lit) tunnel zipping past and marvelling at the fact that it was driverless, and that it could still stop lined up exactly with the platform doors.)

(To re-set thread away from a default train theme) thanks Rick. That was v. interesting.
