Tesla Powerwall

[Grieve]

Did we cross some technological barrier or is this just basically like Apple claiming they invented an idea that had been around for years, but now has rounded corners?

I knew you, Jake or Maul would find a way to get an Apple dig into this thread...

No, the point is that the technology was not there 10 years ago. As with microprocessors/hard drives/etc, battery tech has been leaping along incredibly fast, due both to electric car tech (and especially Tesla), but also things like laptop computers and smartphones. This would have been prohibitively expensive and much, much larger 10 years ago.

What this needs is to get governments (and specifically the US government) on board in a big way. Credits, incentives, but also have these installed in federal buildings across America. Not being reliant on the grid is a pretty big draw there anyway.

Of course, that would be a lot easier with a left-leaning administration like Obama's or (soon) Hilary's. Ted Cruz or Rand Paul, probably not so much.
