ABSTRACT:
A main ellipsoidal drive element is provided including a buoyant internal chamber. The main ellipsoidal drive element defines a main ellipsoid axis, a minor ellipsoid plane, a first ellipsoid end portion, a second ellipsoid end portion, and an outer ellipsoid surface. A drive engagement element is mounted to the first ellipsoid end portion and selectively transfers rotational drive to the main ellipsoidal drive element around the main ellipsoid axis. A plurality of roller elements are mounted around a minor ellipsoid periphery of the main ellipsoidal element. Each of the roller elements are orientated to provide friction reduced rolling in a main ellipsoid axis direction and traction perpendicular to the main ellipsoid axis direction.
