ABSTRACT:
A solar powered tracking device for controlling radiation exposure of surfaces, wherein solar radiation increases the vapor pressure of a liquid in a sensing device and the vapor pressure acts on opposed pneumatic cylinders to produce mechanical movement of the controlled surface to track the sun with a maximum deviation of not more than 0.5.degree. under normal clear sky radiation conditions.
