It's the sweetest dream of every electric-car fan: a battery that could store enough energy to offer up to 1,000 miles of real-world range. While it's not going to arrive in showrooms any time soon, Israeli startup Phinergy thinks its aluminum-air energy storage device might just be that battery. Moreover, say CEO Aviv Tzidon, the company has signed a contract with a global automaker to deliver production volumes of the device starting in 2017. Which isn't really all that far away in car time, since we're already seeing 2014 model-year cars on the road.
