Cold plasma ozone generator

A cold plasma ozone generator to generate ozone from oxygen in a gas, said cold plasma ozone generator comprising:

• an inlet gas port;
• at least one in-electrode, said in-electrode having a plurality of holes proximate a perimeter of the in-electrode;
• said plurality of perimeter holes are in fluid communication with said inlet gas port, said plurality of perimeter holes configured to allow gas to pass therethrough;
• at least one out-electrode, said out-electrode having at least one hole at the center of the out-electrode, said at least one hole configured to allow gas to pass therethrough;
• said in-electrode and said out-electrode configured to maintain AC voltage therebetween;
• at least one spacer between said in-electrode and said out-electrode, said spacer configured to maintain a constant-width gap between said in-electrode and said out-electrode, said constant-width gap configured to allow said gas to pass through said plurality of perimeter holes in said in-electrode and then radially inward from the perimeter of the gap to said at least one hole in said out-electrode;
• and
• an outlet port in fluid communication with said at least one hole in said out-electrode.
