Meanings of cool superconductor in inglés

Perhaps the closest example yet to Marty's machine, this gadget houses a liquid nitrogen- cooled superconductor to float above a hidden magnetic track.

Constructed using bamboo and other materials used in the manufacture of its cars, the Slide hoverboard works using liquid nitrogen- cooled superconductors and permanent magnets.

Ships might have flown to the shadow squares, reopened the power beams so that other liquid-helium- cooled superconductors could be adapted to the power beam receivers.
