If you had a 100 ampere service and your meter had a Kh of 3.6 (see
my recent article) and you pay $ 0.10 per KWH, each revolution is about
1/28 of a cent.
78 rpm indicates an instantaneous load of about 16.8 KW, so at that
rate you'd be paying the utility $ 1.68 per hour. Them rpm's add up
fast! :-)
