Submission + - Panasonic 'Home Batteries' Power Houses for a Week (nexus404.com)
tjansen writes: Panasonic has announced plans to create 'home batteries'. They are lithium-ion batteries large enough to power a house for a week, making energy sources such as solar and wind power more feasible. Also, you can buy energy when it is cheapest, and don't need to worry about power outages anymore.
