Tesla builds a house battery. But does it come in race car red?

Getting off the grid getting easier? Tesla's trying to make it that way, by employing the battery derived from its Model S vehicles.

The battery, plus installation, will cost roughly $3,000. Then there's the tiny matter of solar panels, which are sold separately, of course.

The true benefit won't come from this first generation of batteries, necessarily--storing solar power in a battery is still highly inefficient--but in bringing investment and research into the next generations.
