Do we need to invent anything? My understanding is that most of the grid in the US operates on 3 phase, and some buildings (including residential) already have a 3 phase supply to operate AC and industrial applications.

All we are missing is for it to be standard to wire the 3 phase distribution throughout buildings to every outlet (preferably in a backwards compatible manner; in theory converting 3-phase to single phase is just a matter of ignoring a wire. I would assume that a) the grid can handle people doing this and b) doing this with out current 3-phase standard would result in our current single phase standard,

I hate those 3 phase residential buildings, because they usually deliver 208V to ovens and dryers instead of 240V.

While the appliances are probably approved fo 208V, I doubt they’re drawing more peak current to make up for it.
