The Future of technology with regard to Edison & Tesla will be a hybrid home whereas new homes be required to be wired with the traditional AC (Alternating Current - Tesla Design) for higher voltage/current applications; electric range, dryers, etc, but also be outfitted in almost every location with low voltage DC (Direct Current-Edison Design) for powering LED lighting, computers, cell chargers, etc. The huge advantage of adding low voltage DC to all locations within a home is not needing a expensive and wasteful inverter to convert free solar energy to AC and back to DC to power these same low voltage DC devices. Solar becomes much more affordable and practicable to to run all the existing & new low voltage DC devices!
