Claim 18:
19. An electrohydrodynamic (EHD) rotary system, comprising:
at least one rotary device comprising a hub portion, an axis of rotation, and at least one blade extending radially from the hub portion to a tip thereof, the a least one blade comprising a front leading edge, a back trailing edge and top and bottom surfaces that extend between the front and back edges;
at least one rotary electrode emitter, the at least one rotary electrode being electrically conductive and coupled to the at least one blade of the at least one rotary device proximate to the back edge thereof;
at least one counter electrode, the at least one counter electrode being electrically conductive and positioned proximate to the at least one rotary device in a spaced relationship;
an electrical system comprising a voltage source including a first terminal that is electrically coupled to the at least one rotary electrode emitter and a second terminal that is electrically coupled to the at least one counter electrode, the voltage source comprising an electric potential difference between the first and second terminals that generates corona discharges from the at least one rotary electrode that form flows of ionic wind emanating therefrom that rotate the at least one rotary device about the axis of rotation in a first direction; and
wherein the hub portion comprises a shaft extending along the axis of rotation, and wherein the shaft comprises an electrically conductive portion that is electrically coupled with the at least one rotary electrode emitter.
