The United States’ copper-based electric grid is estimated to leak electricity at an estimated five percent per 100 miles (161 km) of transmission. With power plants usually located far from where the electricity they produce will actually be consumed, this can add up to a lot of wasted power. A weave of metallic nanotubes known as armchair quantum wire (AQW) is seen as an ideal solution as it can carry electricity over long distances with negligible loss, but manufacturing the massive amounts of metallic single walled carbon nanotubes required for the development of this “miracle cable” has proven difficult. Now researchers have made a pivotal breakthrough that could make the development of such a cable possible.
