Musk on Tuesday, Nov. 5, 2013, blamed a shortage of lithium-ion battery cells for trouble meeting demand for Teslas lone vehicle, the Model S. Cars that could have been sold in North America were diverted to Europe to satisfy waiting customers, Musk said on a conference call after releasing third-quarter earnings. (AP Photo/Paul Sakuma)
