But, where is the trunk for my PT?

Pretty cool video. Too bad it's just film magic.

I can give you a boring number of reasons why it's not presently feasible even as a real prototype. But I'm pretty sure that when and if it does become feasible, it won't be levitating that high. There's just no point in making it more difficult. And it will take a lot more than "minerals underground" on the part of the roadway to make it work.

Bob you just rained on my parade. I want one or better yet to use the technology on my computer chair.

Sorry. Reality is like that sometimes.

If you don't mind needing a supply of liquid nitrogen, lining the floor with a whole bunch of very strong magnets, and some rather expensive materials, you could do a computer chair today.

You can get some of the stuff you need here:

Somewhere I've seen video of one people put together big enough to stand on and travel a few meeters.

There are other techniques, too -- more complex, but perhaps more practical (cheaper, easier to maintain, no cryogenics).

But a simpler option would be to get a big blower, feed air to a chamber under your desk, and drill lots of little holes -- like an air hockey table.
