This really belongs in sci.electricity, but since there isn't one, here goes:

I have a swimming pool, which has a filter pump that runs all summer.
Over the weekend I had a conversation with the local pool supply
company service person.  We got on the subject of pumps, and he asked
me if my pump was ok, and how it was connected.  I told him it was connected
to 110V (by previous owner), but it could also run at 220.  He said I
should convert it, that this would give a great savings in the power bill.

Well, I went home wondering how this could be true.  I examined the
pump motor, its rated:

	9  amps @ 220v
	18 amps @ 110v

So, in my mild knowledge of electronics and Ohm's law, Power = E x I
1980 watts in both cases.

So somebody please tell me, is the pool guy whacko, or am I missing
something?
