New superconductor wires carry 40 times more electricity

Wires made of superconducting materials developed by Tel Aviv University can deliver 40 times more electricity than copper wires.

One of the drawbacks of traditional copper wires is that it is heated during power transmission, which results in energy wastage. But the wire made from superconducting materials developed by scientists at Tel Aviv University could transmit 40 times more electricity than copper at the same size due to heat absorption.

Superconducting wires are made of sapphire crystal fibers covered by a ceramic mixture. Each wire is thicker than a human hair that is capable of transmitting a large amount of electricity. The disadvantage of this type of wire is that it always requires cooling to maintain the superconducting state. However, the disadvantage has been solved by a closed-loop cooling system using cheap liquid nitrogen.

There have been studies of superconducting materials before, but the material is not durable and expensive.

Dr Boaz Almog, one of the researchers, believes that sapphiretic superconducting cables are ideal for providing power from remote power sources or for use in the national grid.
