That article might drive the EEs here a little batty.
AC doesn't actually flow. The electrons jiggle.
I checked a few pages down and found another obvious error.
There is another mistake he http://tinyurl.com/4dv2hch
just above the watt hour meter.
What, the step-down transformer? What's wrong with that?
And I have to disagree with you; who says AC doesn't flow? During the
positive half-cycle, current flows (electrons from negative to positive,
or "conventional current flow" in the opposite direction).
I have no idea where I read that thing about electrons just jiggling
in an AC circuit. Curiosity got the best of me so I snooped a bit.

I suppose this explanation falls apart if looked at from the POV of
quantum physics, but for an explanation of current flow from an
electrical standpoint it's perfectly valid.
