One of the limitations of traditional copper electrical wiring is the fact that the metal’s resistance causes the wire to heat up, and some of the energy being carried through the wire is lost in the form of that heat. Wires made from superconducting materials, however, would have no resistance, so could transfer much more energy. While previous attempts at the technology have proven too fragile or expensive, researchers from Tel Aviv University have now developed a new type of cost-effective superconductive wire, that they claim can carry 40 times more electricity than copper wiring of the same size.
