ABSTRACT:
A volatile liquid is circulated through a normally closed circuit, including expansion tubes within an expansion chamber where the sun's rays are focused on the tubes to heat the liquid, transforming it to an expanding gas to drive a fluid-operated motor, also in the circuit. The motor may drive a mechanical load or an electric generator. The generator drives a pump which compresses the gas back to a liquid state and returns the same to a reservoir and to the inlets of the expansion tubes in the expansion chamber. An air reservoir which is pressurized by a pump driven by the fluid operated motor has its outlet connected to the motor inlet so that during periods of darkness or cloud cover in which the volatile liquid is not expanded into a gas, the pressurized air will be automatically fed into the motor to continue to drive the same.
A gimbal system automatically controlled by sun tracking devices supports the expansion chamber to continually focus the sun's rays onto the expansion tubes, regardless of the relative position of the sun and the base on which the gimbal system is mounted.
