I'm a fan of renewable energies, most of which come in the form of electricity generation. Which is a good thin since most of our energy needs are in the form of electricity. So, it comes as no surprise when I see articles like this, that electric batteries may soon be able to store 2-3x their current loads I become excited. Not only for my cellphone, which lasts 4 hours or so these days, but for electric cars, trains, and yes, whole-home systems.
