Armchair Quantum Wire
“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.
The key was finding the right balance of temperatures, pressures, reaction times and catalyst ratios to promote growth and retard etching.
