Re: 1939 Worlds Fair GE Exhibits

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.

I came across the following searching for information regarding a Tesla coil my Dad says he saw at the 1939 world fair. I didn't find the Tesla coil, but found what looks like a jacob's ladder with rotating electrodes. Not specifically Tesla related, but thought the group would enjoy:

It's a fascinating display, looks like it might be three phases arcing together? No sure what to make of it.

If anyone has any detail of a Dr. Moon at the fair, please let me know. Apparently he would stand on the top of his coil and let the streamers come from his fingers.
