All seven of its California stations will close immediately.
A lot of things these days might benefit from a 12vDC rail everywhere, but that’s terrible for power transmission. Low volts, high current, fat cables. Not going to work.
High voltage DC isn’t much use to anyone. You’ll still need switching power supplies everywhere to step it down. Also, connecting it to a human can be really bad.
Yes high voltage AC is a bit of a pain, but not sure anything else is better.
