Elon Musk unveils the Tesla Powerwall

This is awesome. It's so cool to see someone like Elon Musk with truckloads of money trying to do something to change (dare I say “save”) our world. (I think if Steve Jobs could have given this presentation, it would have been all that anyone would have been talking about today.)

One great quote: “Oh wow, (look at) the grid, it’s actually zero. This entire night has been powered by batteries. Not only that, the batteries were charged by the solar panels on the roof of this building. This entire night, everything you’ve been experiencing, is stored sunlight.”
