One experiment I definitely plan to try is to measure the fast current 
waveform _directly_ at the base of a major output streamer.

Since the top electrode will be large enough to accomodate a person,
a digital storage scope and a small Honda generator, one could simply
fashion a long insulated probe that is grounded to the inside of the 
electrode, then stick the tip out thru a small opening in the electrode 
wall and 'go fishing' for arcs!  A fast Pearson CT could measure the 
probe current when a suitable arc emanates from the probe tip, and the 
scope could then capture the waveform, from the relative safety of the 
interior of the top electrode.

BTW, does anyone have a nice storage scope with a 3.5" floppy drive?
