Better efficiency ? you mean smaller cable. Cheaper long distance
transmission. Or why doesnt Energy Star , EPA and every green
orginiation admonish us from being 120. I can easily but a 240
Frige, TV, AC anything I want. I hear nothing about Americas 120 v
system. 240 is jn in every house , if it made 1% difference then off
grid Solar , Wind generation, and greens off grid would talk 240 all
day long, they dont. If that were true where is 480 AC So Im
listening , and willing to learn.
