What is "superconductors"

Usage examples of "superconductors".

I developed the room-temperature superconductors that allowed a much-improved computer to be built, and helped put it together.

Heavy power-cables snaked across open ground, some of them superconductors running from hot, crude, hastily built lasers to a Donau that steamed and boiled around them, and there were radio-wave towers whose archaic shapes hinted at the hand and mind of Tesla.
