it took a capacitor the size of a large thermos to store a charge (don't
remember the value). Took about 5 minutes of charging time off the
alternator, which I had custom installed to provide an extra 15-20 amps.
It used a radar detector type horn with a souped up magnatron from a big
microwave, and a large voltage ladder/network (4 ladders in parallel,
each 20 steps, at around 10-15 kv per step) fed from a custom built
flyback and flip/flop operated SCR feeder from the capacitor.

I kept the ladders soaked in an oil bath, rather than the typical
RTV/silicone coating, as I frequently needed to replace diodes.
