The world's energy infrastructure may soon undergo significant change; Tesla Motors recently unveiled the Powerwall, a compact, lithium-ion battery pack that will allow residents to autonomously consume energy by drawing from their own sun-powered reserve. For just $3,500, you can purchase an attractive, wall-mounted battery capable of storing up to 10 kilowatt-hours of energy - about a third of what the average US household uses daily. Beyond this, the company will also be offering scalable Powerpacks to businesses and utility companies that will allow limitless storage. Powerwalls will go out for delivery this summer.
