Two months later, however, Lexus admitted the video had been filmed in a skatepark where the special tracks needed for the board to work had been covered up.Īfter receiving a 'hover conversion' in the future, Doc's DeLorean is shown folding up its wheels and flying in the second installment of the trilogy (pictured). It was initially unveiled in a stylish video, at which time, the firm refused to reveal how it worked. When placed above a track containing permanent magnets and cooled to its operating temperature, the track's magnetic flux lines are 'pinned' into place, maintaining the hover height of the board. These are housed in cryostats, or reservoirs of liquid nitrogen that cool the superconductors to -197☌.
and is made from an insulated core, containing HTSLs (high temperature superconducting blocks). It uses a combination of superconductors, magnets and liquid nitrogen to 'levitate'. In June, Lexus revealed what appeared to be a working prototype hoverboard called Slide. Mr Henderson is expected to unveil a follow-up model later today and this could more closely resemble the board in the film.
Unlike the Back to the Future board, though, the technology requires it to be on top of conductive materials - such as copper or aluminum - to serve as a secondary magnetic field.
