The resistivity of copper at room temperature is 1.7 10 − 8 Ωm. Thus, the decay time for a copper coil at room temperature of the same dimensions and inductance would be less than 0.1 ms. Superconductors are thus indispensable for magnetic energy storage systems, except for very short storage durations (lower than 1 s).

It was discovered more than 100 years ago in mercury cooled to the temperature of liquid helium (about -452°F, only a few degrees above absolute zero). Early on, scientists could explain what occurred in superconductivity, but the why and how of superconductivity were a mystery for nearly 50 years.
Room temperature superconductors have applications almost EVERYWHERE in the realm of electricity.
