This is an interesting solution to the the upcoming problem of what to do with used electric auto batteries.

http://news.nationalgeographic.com/n...car-batteries/

"Imagine a future in which old electric-car batteries are deployed in neighborhoods as energy-storage systems that guard against power outages, while paving the way for wind and solar power—and more electric cars. The idea has moved one step closer with the demonstration of a boxy unit of used Chevy Volt batteries capable of providing enough electricity to power three to five average American homes for up to two hours.
