Levitation, the ability to appear to defy gravities bonds, has long fascinated humanity. From flying carpets to flying nuns it has long been part of our culture. There is a modern take on this ancient story as well, Superconducting Levitation.
Seemingly able to cancel out gravity and allow objects to levitate, it seems to be the answer to giving us mere mortals at least one of superman’s powers, the ability to fly. Unfortunately superconductors don’t cancel out gravity and we will never fly under our own power, undies on the outside maybe. Instead the levitating effect called Quantum Levitation uses a number of the unusual properties of superconductors to create the effect.
All current superconductors need the cold to enter their superconducting phase. In this phase electrons are able to move about without any resistance, power loss or heat generated, which is typical for most wires or electronics that use ordinary conductors :: Read the full article »»»»
