	I found it quite surprisng that Glascoe et all give a lot of discussion
to rotary gaps and say that despite experiments with "spark gaps
designed for radio use" straight tungstern wire electrodes seemed to
work as well as any!  The power they worked with seldom exceeded 2 kW
average, and the peak currents were probably only 100 amps or so.
