Abstract

In one embodiment, a rotary device includes a multiwall nanotube that extends substantially perpendicularly from a substrate. A rotor may be coupled to an outer wall of the multiwall nanotube, be spaced apart from the substrate, and be free to rotate around an elongate axis of the multiwall nanotube.
