Electric motors are in almost everything these days. From electric cars to robots to generators, the list goes on. Each of these requires expensive and heavy materials like copper and rare earth elements, all of which are resource-limited and will only get more expensive over time. But scientists have come up with a new design that uses carbon nanotubes and, believe it or not, no metal whatsoever. Is this a game changer? Or just another even more expensive pipe dream?
