I love this idea. But I suppose you would have to have dedicated outlets for DC?
Thats a pain.
However, as everything these days seems to have processors and need DC
--and as these power bricks are not only a PITA
--but also tend to drain trickle charges of electricity that can add up
--so a whole house solution could be awesome.
Anyone out there know enough about electrons to know if it would be possible to set something up like this without the trickle loss of electricity? Or is there something about having a hot AC outlet that is inherently wasteful?
There are probably quite a few reasons why no solutions exist.
It's one thing to hardwire a bunch of DC circutry for say 12 volts, or 24v. The problem is every device you own, is going to have different power requirements. If you have 5 different devices they probably run at 5 different voltages, so they're still going to need 5 different transformers/rectifiers.
Another thing is that DC transmission isn't as efficient as AC. As much as powerbricks suck, it's more efficient to have the 3 ft of wire from your powerbrick to your device running DC than 30+ft running though your wall to a transformer in your basement. Also DC typically requires larger guage wire to carry the equalvelent Amperage/Voltage Combination of AC.
It's a tradeoff, lets say someone made a magic transformer box that say had 24 circuits that came out the back, and you could dial in a voltage and amperage per circuit. Now you're adding to the complexity and expense of the wiring in your house. Now you'll have to get some standardized plug to use with it. What happens if you accidently plug in your cellpohne, into your Mac Mini Socket? Your cellphone is probably toast, or at least the battery is.
I think it probably comes down to KISS, Powerbricks suck, but they're pretty easy to use, and hard to screw up.
It could be possible to come up with a solution for this, but when it's all said and done It's not necessarily going to be better, just different and more expensive.
Also, I am by no means an electrican, or electrical engineer, I just hang out with a bunch of wind power nerds.
