Title: Liquid metal current collector with compliant brush having flooded filaments

Abstract: An electrical current collector for an acyclic machine employs a rotor collector ring encircled by a stator collector ring to which a compliant brush of electrically conductive filaments is attached. The gap between rotor collector ring and stator collector ring, including brush interstices, is flooded with liquid metal which is drawn around the rotor collector ring periphery when rotation begins. A thin film of liquid metal on the brush makes sliding contact with the rotor collector ring, enhancing conductivity between the rotor and stator collector rings through the brush filaments.
