"Folks may not realize that power is transmitted in three phases in the US" My office in the UK has three phase power (I own it.) The phase shift thing is to enable putting more power into a place and nothing to do with "so that we basically always have at least one phase providing power at any time." whatever that means. My home only has one phase because I don't need to draw that much power here (yet.)

"so that we basically always have at least one phase providing power at any time" is sort of what makes things like AC motors run better on 3 phases.

  They're also self starting and trivially reversible. Single phase motors require a separate starting arrangement.
