How Superconductors Can Save Energy
At very low temperatures, some substances and elements exhibit strange properties that do not appear at higher temperatures. Scientists know a lot about superconductors these days and have found many of the properties are commercially useful.
One problem with electricity is that a large percentage is lost in the grid through inefficiency and wastage before it reaches the homes, meaning that there is a sizeable scope for improving efficiency and reducing the use of energy in the process, which would be good for all of us.
Now scientists have managed to make a superconducting wire that when suitably cold ensures many less losses of energy during transmission, greatly improving the efficiency and reducing wasted energy in the process. There is now a superconducting cable in New York state, no less, and if it proves to work in practice then it could presumably be spread around the world.
