  • Patent number: 11291972
    Abstract: A method of dissociating hydrogen and oxygen from a water molecule comprises isolating a predetermined volume of water between concentrically-mounted electrodes; applying a magnetic field across the predetermined volume of water, the magnetic field focused radially and attracting diametrically across the electrodes; exciting water molecules in the isolated volume of water to a resonant harmonic frequency; and synchronously applying short burst high voltage, high frequency AC pulse packets to the isolated volume of water to create an electric field. The AC pulse packets have a burst width of up to 1 millisecond and a voltage up to about 10 MV, and generate an oscillating electromotive force which acts on the excited water molecules to dissociate hydrogen and oxygen.

In one embodiment, each of the anodes may be coupled to a power supply through an intervening electrical switch. A switch controller enables the selection of which anodes should be turned on or off during processing. In this way, current density across the anode assembly can be controlled in a uniform manner by turning on and off select anodes. Turning off a portion of the anodes may lower current density in that region. Likewise, turning on the portion of anodes will increase the current density in that region.
