A few days ago, the official YouTube channel of the Lexus company, just released some sort of a triler of what seems to be a functional hoverboard design.
The company Lexus teamed up with experts in super conductive technology to build a working hoverboard prototype.
The technology behind this is called: Quantum Levitation and this device uses this magnetic levetation with liquid nitrogen-cooled super-conductors and some fixed permanent magnets to make sure the board is levitating and gives it a frictionless movement.
