Edison did ofcourse protect his interests. I have read somewhere that he mad the electric chair for AC to scare people from choosing AC and keep up with DC.
I guess if someone should decide a new standard today with no hence of history, and whats available we had higer voltage DC in our houses, almost no loss, and easy to convert to suitable voltage and frequency with modern technology. Higher voltage, thinner wires, less copper.
To expensive to do all that, but maybe with combined 120/240V in north American houses the 240 could win. Most 230V equipment made for other countries (mainly with 50 Hz) will run Ok on 240 (60Hz)
