The home of the future will be DC

The arguments against DC power 135+ years ago found Edison on the losing side because DC power doesn't travel well.  But now, DC power can be created at your home, and many, and soon most, appliances will run natively off of DC power.  Already, TVs and computers require AC to be converted to DC to run.  Refrigerators and air conditioners are heading in the same direction.  Have these guys at Purdue built the house of the future?
