ABSTRACT:
An ion engine which produces thrust by charging a propellant vapor in an electric field and then reversing the polarity of the electric field. The electric field forces the charged nuclei close to the unenergized electrode. When the electrode is energized as a positive electrical charge, the nuclei repel and create thrust in the opposite direction.
