A more practical solution would be special J boxes that have the
transformers in them and are sensitive to loads being plugged/
unplugged and cut off power to the primary when not in use. Everyone
hates wall warts, they draw a little current even when not in use.
Your electrician would then install these low voltage outlets easily
throughout the house. The important thing is that they be able to
detect "no load" and cut off the primary, and sense an item being
plugged in or turned on and re-connect the transformer primary. Your
whole house DC distribution idea would not be able to do this because
it has to be "ready" globally with no local outlet control sensors.
There is no reason that could not be designed into wall-warts.
I've never measured the quiescent primary current draw of old
style wall-warts verses the newer tiny switcher wall-warts, I'm
sure someone has done so. I think your idea is great for office
cubicles because it could be built in during manufacturing and
would help lead to a less cluttered work space, at least for
This could have been a very interesting thread if it were not for the
few insecure nerds/geeks who think they have to prove something about
their engineering prowess, and just wind up looking like a person with
drastic insecurity issues.
I did however offer a marketable solution to your proposal, if you can
find it somewhere in this mess.
Few others of these supposedly "illustrious" engineers actually
offered anything worthwhile from what I can see.
