Lexus Hoverboard: How they did it

The Lexus Hoverboard technology features two “cryostats”—reservoirs in which superconducting material is kept at -197 degrees (-127.22 degrees celsius) through immersion in liquid nitrogen. The board is then placed above a track that contains permanent magnets. Dr. Oliver de Hass, evico CEO, said: “The magnetic field from the track is effectively ‘frozen’ into the superconductors in the board, maintaining the distance between the board and the track— essentially keeping the board hovering. This force is strong enough to allow the rider to stand and even jump on the board.”
