The Hoverboard is here (sort of)

Not a one of them wearing a helmet. Duh.

The board looks really cool - I'm guessing liquid nitrogen for super conductivity of some sort (?) Probably insanely expensive to operate though, but a very cool R&D piece.

I'm calling BS - how would it have any lateral stability? It resists being pushed sideways but is more than happy to move forward.

There is another video showing how they constructed the tracks for it to ride on. It works similar to a maglev train.

I call BS. They're showing this thing as if it has some sort of lateral "traction" that prevents what I guess what would be called "drifting" in a car. The gyros needed to do something like that would be larger than the board itself.

Edit: Amail beat me to it. :D

Tracks?! Gee, that's not cheating or anything.

:rolleyes:

Yes, tracks like the train where it rides above the surface on magnetic levitation. Like I said, it is here sort of. It does hover for about 20 minutes until the liquid nitrogen keeping the superconductors cold runs out.

Total BS. To hover over water it would need to displace water equal to the weight of the rider and board.

Why, it isn't displacing the air it is hovering in? A float plane doesn't have to displace any water to fly over water.

Why does every video... even the how they did it version have to have techno blasting throughout??

They are Japanese. Mostly.

Not techno, breakbeat. Really awful breakbeat.

But WTF is the point? It runs on rails. I made a LN2-cooled superconductor and floated it in freshman chemistry--in about 2 hours.

Fine and dandy, but could you ride it?

Yes, if I had made enough of them. We ran out of ytterbium.

wow that is remarkably underwhelming.

Yeah, has to ride on a track and has to be filled with liquid nitrogen periodically... but other than that it is EXACTLY like the ones in Back to the Future... :rolleyes:

I have no problem with Lexus doing this as a publicity stunt for advertising... I do have a problem with the media misrepresenting that "the hoverboard has arrived!"
