The "wall wart" is one of humanity's worst inventions (not counting all of the inventions that are actually intended to kill and maim each other, I'll admit). AC-plug power supplies are a cheap workaround to various engineering, economic, and regulatory problems that manufacturers face, and they solve those problems by pushing them off onto end users. So what can we do about it? OSNews takes a look at an ingenious workaround to the Wall Wart problem, and some hopeful trends that might make them a thing of the past.

I can also image one day having solar PV panels on the roof battery backed and send that power into the house for use only by 12DC computing or entertainment devices, not mess with the AC system at all. So AC half stays on grid, DC half off grid. If the power goes out, the huge AC equipment won't work, but the computer stuff will.

I currently use a 15 watt and a 9 watt solar panel to charge 2 18 amp batteries. I use a USB car adapter to charge my phone and bluetooh headset. I use a 350 watt inverter to run my rooms lights, and charge my netbook.
