| 1. A method of rotating a nanotube, comprising:
(a) providing a multiwalled nanotube attached to a rotor plate, said multiwalled nanotube suspended at opposed portions between
anchor pads on a substrate to permit rotational movement of the rotor plate without hindrance by the substrate, said multiwalled
nanotube having an outer shell that is compromised in a region between the rotor plate and the anchor pad to permit additional
rotational freedom of the rotor plate;
(b) providing at least two stator electrodes adjacent the rotor plate;
(c) applying out of phase voltages to the stator electrodes; and
(d) applying a dc voltage offset to the stator voltages to the rotor plate.
