Development and Testing of the Lexus Hoverboard

The Lexus hoverboard is constructed from an insulated core that contains high-temperature superconducting blocks. These are housed in cryostats — reservoirs of liquid nitrogen that cool the superconductors to −197°C. The board is then placed above a track containing permanent magnets. When the board is cooled to its operating temperature, the track’s magnetic flux lines are ‘pinned’ into place, maintaining the hover height of the board.
