A superconductor is a material that can do electricity or transport electrons from one atom to another with no resistance. This means no heat; sound or any another form of energy will be excites from the material when it has reached "critical temperature" (Tc), or the temperature at which the material suits superconductive. Unfortunately, most materials must be in an extremely low energy state (very cold) in order to enhance superconductive. Research is underway to grow compounds that become superconductive at higher temperatures. Currently, an enormous amount of energy must be used in the cooling process for making superconductors ineffective and uneconomical.
