Claim Text:
1. An atmospheric air plasma source comprising: an electrically conductive outer cylindrical tube having an air intake and an electrically conductive inner conduit coaxially with the outer cylindrical tube and in fluid communication with the air intake; an electrical voltage generator electrically connected to the inner conduit and configured to oscillate at very high frequency (VHF) frequency such that at least a portion of the inner conduit oscillates at the frequency; and a plasma emitting nozzle at a terminal end of the inner conduit, the nozzle recessed within the interior of the outer cylindrical tube from a terminal end of the outer cylindrical tube, wherein the outer cylindrical tube and the inner conduit are grounded at a rearward end that is opposite the terminal end of the inner conduit and the terminal end of the outer cylindrical tube and air received into the air intake serves as a dielectric insulator between the outer cylindrical tube and the inner conduit.
