These eggheads kept "proving" that 60Hz was

Fuller's law of cosmic irreversibility:
1 pot t == 1 pot p.
1 pot p != 1 pot t.
Lets not forget EDISON promoted DC as well.
When you think about it, the RPM of the generator
is the limiting factor. You can't have your moving
parts move too fast.
Or too slow -- hamster powered night light.

Oh, the steel mill had 250VDC distribution, as well as higher
voltages for the overhead cranes and welders.
I once witnessed a plant electrician mistakenly wire a 120v 60Hz
water cooler to 250 VDC. The ensuing meltdown was fun to watch. His
boss told him to pack it back up and return it to stores with a tag
saying something to the effect that it was a manufacturing defect.
