The program which estimates the breakdown potential, when applied to breakdown between spheres, etc, gives roughly the same breakdown voltages as are in the North Report, when I use the low frequency value of 30kV/cm as the threshold. Perhaps with close spheres, etc, the development of leaders and breakdown of the gap follows rapidly from the initial streamers, so that the full discharge appears to be pretty much at the same voltage. Maybe this isn't the case when the electrodes are a long way apart. Maybe the process of streamers combining into leaders doesn't take place until the terminal potential is rather higher? I'll abandon further speculation because presumably the answers are all in > http://hot-streamer.com/TeslaCoils/OtherPapers/phd_plank.pdf which I'll read as soon as I can find a viewer. -- Paul Nicholson, --
