ABSTRACT:
A liquid-tight fluid container forming a primary chamber is provided with a vertical standpipe communicating, at its depending end, with the bottom area of the primary chamber and communicating with an elevated tank and chamber, at its upper end, in vertically spaced relation above the primary chamber. The elevated tank is formed in a fluid reservoir in turn communicating with the depending end portion of the primary chamber through a check valve. Solar rays heat fluid which circulates through a heat exchanger disposed in the primary chamber to expand a volatile liquid therein and force it through the standpipe into the elevated tank. The liquid is returned to the reservoir bottom. The liquid drives a hydraulic motor by its movement to or from the elevated tank or both.
