| Jun 17, 2016 at 18:56 | comment | added | Ben Trettel | Here's an interesting article on the advantages of DC power. Conversion efficiencies can vary from 50% to 90% according to the article. The author advocates using DC if you have solar PV panels on your roof to avoid the conversion losses. | |

| Jan 27, 2015 at 12:35 | comment | added | Rick | The NEC does allow for wiring of low voltage DC power. Some examples are: telephone lines (DC unless the phone is ringing), power over ethernet, and sensitive sound systems.I can't remember how low voltage is defined, but 12 v would definitely qualify. | |

| Jan 27, 2015 at 4:07 | comment | added | George Herold | What's the cost and what's the savings? If you'd want to run any real power through the lines it would be a lot of copper. The local building code will want to make sure your wires don't overheat and start a fire. | |
| Jan 27, 2015 at 4:00 | comment | added | Dan | There are reasons, both practical and political behind the use of AC. I'd expect that you're right in that a single high quality dc supply within the home could do a better and more efficient job than the dozens of light bulbs, computer power supplies, cell phone chargers and other wall warts that we've got. You'd probably still use AC for generation and long range transmission. | |
| Jan 27, 2015 at 3:45 | comment | added | Fred | If you did you'd want to make sure the wiring was easily identifiable from the AC wiring. I wonder if national standards exist for such wiring, particularly regarding colour of the wires and the overall cable? | |
