" What about heat loss in the transmission lines from the converter in the
" walls to the DC sockets?

what devices are we talking about that really get along better with
dc, what voltage are we talking about, and how many of them can be
standardized to a common voltage without sacrificing efficiency?

if we're talking lights only, a houseful of leds probably wouldn't tax
a single 15-20a ckt even at 12v.
