Hi Jason, All! 
        Tripolar coils have been proposed numerous times in the past. 
Theoretically, at any one time there could be arcs between any two of the 
three coils, but they would be somewhat smaller than those produced by a 
bipolar coil. The tripolar coils has been a darling of some UFOlogists and 
other fringe experimenters, but  to my knowledge no one has succeeded in 
building an effective one. Of interest, (IMO) might be a "triple bipolar 
coil". This would be a circle of six, with voltage peaking at the 
diametrically opposed pairs of coils in rotation. If the ionized air and 
plasma in the center did not have time to dissipate, (perhaps inside a large 
globe) the results MIGHT be interesting. Toploads would have to be smaller or 
of unusual shapes so that they were not closer to each other than to the 
center. Such a system would require a fairly large lab area (hear that 
Chris?!) To my knowledge, no one has successfully done this yet either. 
Just some thoughts for the future, 
Matt D.
