Abstract: A high efficiency mechanical transducer assembly including a primary drive assembly defined by at least one but preferably a plurality of synchronized conveyors being vertically oriented and structured to travel in a continuous path which is defined in part by a downward path segment and an upward path segment. A plurality of elongate arms are movably coupled at proximal ends thereof so as to move with each of said conveyors and relative thereto such that the arms automatically assume a collapsed position when travelling along the upward path segment and an outwardly extended position when travelling along the downward path segment.
