Ok, the hoverboard has been invented, and you can buy one. Delivery in a year.
All right, not QUITE that simple, but intriguing technology nonetheless. Kind of "cheap maglev without some of the restrictions".
The designer has in mind putting it under houses so they can lift off the ground in earthquakes. And he wants "the world" to come up with ideas for actual uses - the hoverboard is really a just a novelty eye-catcher.
My vote is to put it under car seats. Then you get the ride quality benefit of magnetic suspension without altering the existing infrastructure of the car or the road. If I can think of that in 30 seconds (although someone can knock it down in ten no doubt) then with a bit of thought it could actually be interesting.
Just one of many links - Telegraph in this case - here:

And their actual Kickstarter page with videos and stuff (yes, you can pay for one right now, and I see someone in the last ten minutes actually has) is here:
