An oxygen allotrope generator having a tube with an electrically grounded outer surface and an electrically positive inner surface. A plurality of corona reaction plates are spaced along the interior of the tube, the plates being longitudinally inter-connected by wires and being in electrical connection with the electrically positive inner surface of the tube. An outer jacket encloses the tube and provides a second linear pass for partially ozonated gas to flow in the generator. An alternative embodiment includes external distributed ground connections at the locations of the corona reaction.

A mobile system is described that that produces and applies an ozonated liquid to clean and sanitize a variety of articles and surfaces. The mobile system includes an ozonated liquid dispensing unit that forms the ozonated liquid from water and ozone gas.
