The inevitable decline of dirty electricity got a bit of a boost with Tesla’s announcement of a way to store energy in your household via lithium-ion cells with a liquid thermal-control system… let’s just say they’re battery packs connected to the internet able to store a couple of days juice. It’s called a “Powerwall” and peeps love it. Awesome huh?
“You can reserve a Powerwall right now on Tesla’s site. The device will also be available via distributors, with the 10kWh version offered to installers for $3,500, while the 7kWh model will cost $3,000. This doesn’t include the cost of a DC-to-AC inverter to work with your home. (Solar cell customers will already have that inverter.)”
