    Tesla's founder, Elon Musk, sees the $5 billion facility as a key step toward making electric cars more affordable, while ending reliance on oil and reducing greenhouse gas emissions. Yet the so-called gigafactory may soon become an existential threat to the 100-year-old utility business model.

Or a battery not only able to provide many times more energy than today's technology but also at significantly cheaper prices, meaning longer-lasting and less expensive power for cellphones, laptops and even the home. Those are among the ambitious goals of the $120 million, Department of Energy-funded Joint Center for Energy Storage Research.
