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.

It wouldn't be feasible. Have a look at the wiring in your car to see how complicated and expensive it would be. Lower voltage means much higher amperage. This requires very thick wiring and relays on all switches to prevent arcing or contact melting. An electric kettle or toaster would need a cable as thick as a garden hose and would need to be hard-wired.
