Filed: 2001-07-11
Abstract: This device is a brushless high-voltage electrical generator for producing a  high energy external electrodynamic field or continuous quasi-coherent DC corona or arcdischarge of uniformed current density which completely enclose s the machine's conductive housing (1). This housing is divided into distinct electrical sections (3-5) and contains a flat conductive rotor (6) electrically links separate negative (3) and positive (5) housing sections a nd upon which a plurality of toroidal generating coils (35, 40, 56) are rotatab ly mounted. Circular arrays of stationary permanent magnets (34, 39, 55) are affixed within the housing which induce a constant DC voltage within said coils upon their rotation. The primary voltage generated is electrostaticall y impressed across the rotor such that great quantities of electronic charge m ay be transported between the opposite polarity sections (3-5) of the housing, in such a manner that a much higher secondary voltage is caused to appear acros s interposed neutral sections thereof, and the resulting external breakdown current once initiated is independent of the generating coils'ampacity. Ancillary mechanical, electrical, and/or electronic features may be attached  upon or within the housing to aid in harnessing and controlling the useful effects associated with the external dynamic electric field produced by the device.
