What’s the secret to building a more affordable electric vehicle? JB Straubel has an answer. It starts with a pile of old cell phones.

Almost every day old iPhones and other used personal electronics arrive by the truckload at a warehouse in Carson City, Nev., where workers crack them open, pull out their batteries and strip them for raw materials.
To JB Straubel, one of the brains behind Tesla Inc., that refuse holds the key to driving the electric car revolution forwardand making the vehicles affordable enough for everyone to own one.
