Gyrobus G3, the only surviving gyrobus in the world (built in 1955) in the Flemish tramway and bus museum, Antwerp. A gyrobus is an electric bus that uses flywheel energy storage, not overhead wires like a trolleybus.The name comes from the Greek language term for flywheel, gyros.While there are no gyrobuses currently in use commercially,
