True, but they use 50 Hz rather that 60 Hz in the US. That makes for
bigger transformers. If we were serious about saving, we'd increase
the frequency to about 10,000 Hz.


Who's going to pay for replacing every alternating-current motor on the
continent?


Plus I'd bet that the significantly higher capacitive currents between
conductors would waste a huge amount of power in resistive losses.

IIRC 400Hz power was used in aircraft circa WWII, I lost track of
whether it's still a standard there.
