Scientists have made a strong, lightweight wire from carbon that might eventually be a rival to copper if its ability to conduct electricity can be improved, Cambridge University said.
They said it was the first time that the super-strong carbon wires, spun in a tiny furnace that looks like a candy floss machine with temperatures above 1,000 degrees Celsius, had been made "in a usable form" a millimetre thick.
Krzysztof Koziol of the University's department of materials science and metallurgy said that commercial applications were still years away but that "our target is to beat copper".
