Abstract
An apparatus for coupling AC electrical energy from a stationary source to a moving electrical device includes an input for receiving a source of AC electrical energy. The apparatus also includes a stationary, electrically-conductive plate and a moveable, electrically-conductive plate which is proximate to the stationary plate. A power consuming electrical device is electrically connected to the moveable plate. The invention couples energy from the AC source to the power consuming device by means of a capacitive link established between the stationary plate and the moveable plate. In preferred embodiments of the invention, the power consuming device comprises a neon tube or an electrical motor.
