ABSTRACT:
An elongated arm, pivotally mounted at the center to a support structure, includes a large, bulbous reservoir attached at either end thereof. The arm is hollow and a passageway therethrough joins the two reservoirs. A volatile fluid which vaporizes at a relatively low temperature (125.degree. F. or less) is placed within the reservoir/passageway to provide the activating fluid for the device. A source of heat input is provided in heat exchange relationship with each reservoir when pivoted to its lowermost point, causing the volatile liquid to vaporize and flow to the other end where it condenses, causing the other end to lower. An electrical generator or other energy converter is operatively associated with and operated responsively to the movement of the arm.
