Light Activated Rotor
Abstract
Provided is a light activated rotor comprising typically a
plurality of vanes affixed to a hub rotatable around the
longitudinal axis of an axle. Each vane comprises a planar
surface oriented generally perpendicular to the longitudinal
axis of the axle with each vane separated into a first surface
and a second surface. The first and second surface are
adjacent and share a common boundary generally perpendicular
to the longitudinal axis of the axle. Additionally, the
first and second surfaces have differing emissivities. When
the light activated rotor is illuminated with a radiant flux, the
differing emissivities of the first and second surfaces produce
a temperature gradient across the vane and generally
perpendicular to the longitudinal axis, and a thermal creep
force across the planar surface of the vane generates a
revolution of the vane and the affixed hub around the
longitudinal axis of the axle.
