G.E. had a huge Marx impulse lightning generator there.  It produced 
+5 million and -5 million Volts, so 10 million between the two 70 ft. 
tall towers.  My grandfather said it was so loud you could barely 
stand to hear it fire.

They also have a 1 million Volt xmfr setup with AC power arcing 
between xmfrs.  A large series reactor controlled the current on each pri.
