This group seems to have alot of electrical knowledge, sooo.....

The US is 60 HZ and Europe is 50 HZ, a 60HZ motor is more efficient,

I seem to remember reading that Westinghouse-Tesla AC was chosen over
Edison DC because the AC could be transmitted with lower power loss
over distance. So was AC more efficent at the distances it was being
transmitted at the begining of the electrical revolution?
Thanks

Yes, because unlike DC it could be transmitted at high voltage
(requires more cheap insulation or spacing) , low current (requires
less expensive copper) and easily transformed to low household voltage
at the end. The Edison system needed small, inefficient power plants
in every neighborhood. Also Edison wasn't as clever a businessman and
promoter as George Westinghouse, and I think the propaganda film of AC
killing a horse backfired on Edison.
