Researchers have simulated attaching benzene molecules to the outside of a nanotube to form gear teeth. Nanotubes are molecular-sized pipes made of carbon atoms. To "drive" the gears, the supercomputer simulated a laser that served as a motor. The laser creates an electric field around the nanotube.

A positively charged atom is placed on one side of the nanotube, and a negatively charged atom on the other side. The electric field drags the nanotube around like a shaft turning.
