alt Hacker Newsit would probably slowly start coming out as dual ac and dc connections and start with "garage appliances" like your laundry, central ac / vac and car charger since the garage is the cheapest place to wire something into.

I run my garden tools and shed on a 1.2kVA 12V inverter, bought for pennies off eBay. It's just about enough to run my little "lunchbox" flux-core welder on a low enough setting to do thin metal and tubing, perfect for sticking exhaust pipes and such together.
I read an article about a house that was converted to use DC instead of AC as a trial. The most surprising part to me was that most household appliances simply kept working because they already contain a AC/DC rectifier anyway which works fine if you connect it to DC.
