Ten times lighter than copper and 30 times stronger — scientists at Cambridge University are hoping carbon nanotubes will replace copper as a way to conduct electricity in the future.
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 cotton candy machine with temperatures above 1,800 F, had been made "in a usable form" a millimeter thick.
Krzysztof Koziol of the University's department of materials science and metallurgy told Reuters in a telephone interview that commercial applications were still years away but that "our target is to beat copper".
Wire made in the laboratory from carbon nanotubes (CNTs) — microscopic hollow cylinders composed of carbon atoms — is 10 times lighter than copper and 30 times stronger, the university said in a statement.
