Superconductivity is what makes these supercomputers possible.
But until recently, Liquid nitrogen was needed to cool alloys and metals down to insanely low temperatures to achieve the phenomenon.
Look at the embedded video for an example of what a superconductor can do. Start at 2:46.
Scientists seem to have unearthed a rare material that can act as a superconductor.
This discovery will undoubtedly push the human race into the next age of technology.
The implications of this discovery are tantamount to the harnessing and usage of electricity.

A superconductor is an element or metallic alloy which, when cooled below a certain threshold temperature, the material dramatically loses all electrical resistance. In principle, superconductors can allow electrical current to flow without any energy loss (although, in practice, an ideal superconductor is very hard to produce). This type of current is called a supercurrent.
The threshold temperature below which a material transitions into a superconductor state is designated as Tc, which stands for critical temperature. Not all materials turn into superconductors, and the materials that do each have their own value of Tc.

After decades of hunting, scientists recently announced the discovery of a room-temperature superconductor, an elusive material that conveys electricity with no loss of energy at everyday temperatures.
What is a room-temperature superconductor?
Electricity passes throughout a superconducting material without resistance. Superconductors also expel magnetic fields (the Meissner effect). Moreover, a superconductor can maintain an electric current even when a voltage is not applied. Each superconducting material has an associated critical temperature below which the superconducting state is maintained. Above the critical temperature, the superconducting properties are destroyed.
A room-temperature superconductor would revolutionize technology. A superconducting power grid would not lose energy via resistance, so it would result in tremendous energy savings compared with the technology we have today. Superconducting magnets are used in MRI machines, particle accelerators and in magnetic levitation trains.
