Oxygen is ionized with Tesla Coil technology to produce Ozone while passing through a Charged Aperture Disc then is propelled forward as a Cold Plasma Toroid at sub-sonic velocities to a target of your choice to maximum range of 100 m. The vortex carries a variable electric charge capable of disrupting cell phones and of course, delivering an electrical shock for denial of access to property for unwanted guests.

Ozone Vortex Rings can carry a High Voltage Static Charge to any targeted electrically neutral surface at a distance with Tesla coil technology.

An ozone gas torus holds an electric charge and behaves like a capacitor in accordance with the classic skin effect.

Ozone gas configured as a toroidal vortex can behave like a conventional capacitor and store electric charge when oxygen passes thru a circular aperture in the presence of an electromagnet field and is ionized. The surface of the torus moves through the ambient air with less resistance than a normal object.

Tesla Coil details & nomenclature showing how the Ozone torus is generated and how it interacts with the electro-magnetic field from the Tesla coil.

Upon leaving the aperture, the cold plasma torus is guided by the collimator tube that carries some residual electric charge thus helping preserve the toroidal geometry as the ring accelerates through the tube.

Oxygen is an ideal gas but expensive. Neon or other halogens would probably work too given the right pressures and volumes.
