My bad. I only remember something about them using DC to electrocute an elephant to prove how much better it was.
I think that was Edison using AC. Apparently it was not part of the war of the currents. https://www.wikipedia.org/wiki/Electrocuting_an_Elephant
That was actually to prove how “dangerous” it was. This was when Edison and Tesla were duking it out, trying to get their respective electricity types established as the standard. Edison and JP Morgan decided it would be a good promotion for alternating current if they publicly electrocuted an elephant with direct current to demonstrate how dangerous it was. Obviously they knew that both modes are dangerous with that much current, but when has marketing ever been about honesty?
It is 60Hz tho (instead of 50) which is stoopid. So you were on the right track.
Why is 60hz stupid? The US was ahead of Europe in terms of electrical development last century and 50hz generators were bigger and more expensive than 60hz generators at the time.
