Speaking of power stories.  One of my uncles helped run a light plant for
the small town where I grew up.  We actually didn't get rural electrical
power until 1954 in Kansas where I lived.  I can still remember going out
to an aunt's house in the country, and they used coal-oil lanterns for
light.  No in door pluming or anything.

Anyhow, the contract the city had with this guy my uncle worked for stated
he had to keep the voltage at a constant range, but nothing was said about
the frequency, so at night, he'd slow the engines down to save gasoline
and keep the voltage up.  Electric clocks didn't keep proper time.  Comes
from people writing contracts who don't know what to include.
