Scientists Replace Copper with Carbon in Breakthrough EV Motor 
A team of Korean scientists has created a small electric motor that works without a single strand of copper. Instead, it uses carbon nanotube cables — ultra-light, ultra-conductive threads of rolled graphene — to spin up power with far less weight. 
This innovation could pave the…
