ABSTRACT:
The power engine includes at least two separate fluid-tight enclosures. A solid mass is associated with each enclosure. A coupling rigidly interconnects the enclosures. A pivot shaft defines an axis of rotation and pivotally supports the engine for rotation from a first position, whereat a first enclosure is located at a first level above the axis of rotation, to a second position, whereat the first enclosure is located at a second level below the axis of rotation. A motive fluid is enclosed within each enclosure whose pressure varies in response to temperature changes. Each solid mass is movable in response to a pressure change in its associated enclosure. The engine is responsive to alternating thermal effects which cause alternating variations in the pressures of the enclosures resulting in alternating shifts of the center of gravity of the engine, thereby rotating the engine about the axis of rotation.
