    As we start to see more and more of these type of USB power sockets around the place, maybe the question is... why are these sockets only 5V DC. Could we get more use-cases for 12V and maybe 24V for homes and offices, especially if every building had a renewable energy source and a big old battery. One feeds of the other, so to speak. Then I suppose, the other question, if this renewable energy source plus battery is working well then I wonder... would we still need AC power sockets in every room in the home or in the business.

    Many years ago, pop 'tronics ran an article on smart plugs that eliminated the need for power supplies in appliances. Even washing machines could use DC moters because they'd just request alternating current synchronized with reversing their drums. Basically you'd get a couple hots and a digital line to request a voltage and amperage from a smart panel at your distribution point.

    I suspect this never went anywhere because the initial cost was high, and appliance makers didn't want to commit to it until it was already ubiquitous.
