Claim 16:
17. An apparatus comprising a cold-plasma ozone generator, the ozone generator comprising: a non-arcing non-coronal ozone production cell capable of generating ozone; the ozone production cell having a pair of electrodes placed on two sides of the production cell and spaced apart by an electrode gap, and a dielectric layer on each of the electrodes facing inward into the ozone production cell; a high-voltage pulse generator attached to the electrodes and configured for producing a glow discharge cold plasma between the electrodes, the high-voltage pulse generator being able to produce sufficient voltage to generate the glow discharge cold plasma; a cooling system attached to each of the electrodes; and an oxygen source adapted to provide gas flow through the production cell in the gap between the pair of electrodes that efficiently generates ozone in the cold plasma, wherein the pair of electrodes comprise two aluminum, brass, stainless steel or copper electrodes at least 0.75-cm thick, the electrodes have dimensions of about 10 cm in width and about 20 cm in length and all edges and sides of the electrode bonded to the dielectric layer have about 1-cm radii of curvature, the electrode gap is defined by alumina or polymer precision spacers, the high-voltage pulse generator is configured to operate at a peak voltage of about 15 kV to 25 kV, pulse repetition rate of about 1 kHz to 10 kHz and pulse width of about 5 ns to 20 ns, and the dielectric layers are plasma-spray coating layers, electron-beam deposition layers, chemical-vapor-deposition layers, sintered layers and/or baked on layers of the group consisting of alumina, sapphire, silica, aluminum nitride, diamond or polymers and are intimately and directly bonded to each of the electrodes without the use of adhesive between the dielectric layer and the electrode.
