If I built a new house today I’d wire 12 volts DC in addition to 110VAC. Safe for kids and fewer unsightly wall warts.

  Also impractical due to I^2R losses.

    Not if you has an in-wall supply in each room.

      I’ll stick with the AC thanks. Having a house full of switchers is going to be hell.

        I already have a house full of switchers, with all the wall warts! I've got at least 15 that are always plugged in.

  Was recently thinking that single pair power over Ethernet could probably handle 90% of the use case for residential power. 50W is enough for a LED/Fluorescent lighting, power a laptop, lighting, charge your phone.
