D'oh! I was actually off by a factor of 100, not 1000. Cost was about 13 cents per KWH. Expensive!!
NB: I shouldn't be allowed to do math. Don't believe any number I compute.

Very cool, Miriam! And I don't see any specs printed on the motor.

What is springloaded? The mount?
I read somewhere (an old manual, probably) that the handwheel should make contact with the edge of the motor pulley, not the center of it. Too much drag or something if you line it up with the center of the pulley. It makes sense intuitively but I can't exactly explain it, physically. (And I shouldn't try to, given my propensity to err.)
