Breakthrough may allow for a nanotube power grid.
Scientists at Rice University have found a way to mass produce long strands of metallic single walled carbon nanotubes, a hurdle which has been holding back the development of a nationwide electrical grid based on nanotubes.
The team has found a way to take small batches of nanotubes and make them much longer.
“Armchair quantum wire” (AQW) will be a weave of metallic nanotubes that can carry electricity with negligible loss over long distances. It will be an ideal replacement for the nation’s copper-based grid, which leaks electricity at an estimated 5 percent per 100 miles of transmission, the researchers said.
