Japanese car manufacturer Lexus posted this video on their Youtube channel yesterday, and immediately every Back to the Future fan on the internet (so that's pretty much the entire internet) sat up and took notice.

We've had the Hendo hoverboard (which uses magnets, but requires a copper surface to hover) we've had the fake Tony Hawk one, and various drone variations that act like hoverboards, but could this be the real deal?

The board uses liquid nitrogen cooled superconductors and permanent magnets...

It's certainly a tantalising prospect - and this video with that little tease at the end - does nothing to make it any less tantalising. And if this is a fake (or a clever attempt at creating a viral marketing campaign) then they're certainly going all out on it.

A press release put out with the video quotes the company's Executive Vice President, Mark Templin, and includes a legitimate-sounding explanation of how the board works.

It explains: "The Lexus Hoverboard operates using magnetic levitation to achieve amazing frictionless movement. Liquid nitrogen cooled superconductors and permanent magnets combine to allow Lexus to create the impossible."

What do you think - real deal or elaborate hoax?
