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.
