Lexus Hoverboard

[index] [1,084 page views]

Lexus has gone and brought the hoverboard from Back to the Future II closer to reality. Their board weighs in at 25 pounds and features liquid nitrogen chilled superconducting blocks allowing for ten minutes of hover shenanigans. But how does it work? The superconductors allow the board to exploit the Meissner-Ochsenfeld effect to “push away” magnetic fields while also taking advantage of flux-pinning “lock” the board into a stable position. Basically, this is the same technology as the quantum locking demonstration from nearly half a decade ago. Just like the demonstration, the Lexus hoverboard can only work on a specially built track.
