Room Temperature Superconductor - this is a BIG DEAL in Physics

 For decades, a dream of many physicists, chemists, engineers and material scientists has been to make a material that can be in a superconducting state at room temperature. Generally, superconductors have been a variety of materials that, when made really cold, like using liquid helium to cool down around 3 or 4 Kelvin, could lose all their electrical resistance...yes, R = 0...that is a superconductor. 

In this state, when an electrical current flows through the superconductor, there would be NO energy loss at all. You could maximize the current. At Fermilab, a superconducting solenoid would produce very strong magnetic fields on my old experiment. MRI machines are possible because of these types of superconducting magnets. 

But think about room temperature. If we could make wires and run electricity through them in a superconducting state, the nature of power production and distribution becomes totally efficient, with no heat loss in the wires. All aspects of our electronic, energy dependent world would be affected over time, in a positive way. Here is a ETHS grad's (Jaime B.) explanation of superconductivity in general:
