Abstract
Abstract Automatic tracking of a source of radiant energy to pivotally displace an energy collector panel assembly for optimum concentration of the radiant energy absorbed. Changes in magnitude and/or location of the source relative to the collector produces a change in differential air pressure in a sensor to displace the center of mass of a gravitational drive device through which tracking movement is imparted to the collector panel assembly.
