Abstract:
A centripetal impeller to impart a force and having an attachment piece defining an axis of revolution. The impeller has a movable arm pivotable relative to the attachment piece so that the movable arm is a distance r from the axis of revolution. The impeller includes a rotation device coupled to the attachment piece causing the attachment piece to rotate along the axis of revolution. A variable force device is attached to the movable arm to produce a force on the movable arm toward the axis of revolution so as to cause a net force along the axis of revolution.
