New Tesla battery could power your home, and maybe the electric grid too
I like the idea of having solar cells that charge up a bank of batteries that could power my house at night.  I was recently talking to a Solar City rep and they are thinking along those lines.I wonder if this would be a good time to define a standard low voltage plug for house hold use. An awful lot of modern electrical devices don't need 110VAC and end up wasting a lot of power converting AC to DC. I've seen replacements for wall sockets that combine a single AC socket with a few USB power ports. That's convenient, but USB wasn't designed as a power plug, it's just been co-opted for it. A well designed system of 24VDC or 48VDC would be a nice thing to have. Bonus points if it's a world standard.  I'd also like a pony.
