GERMANY-US-AUTOMOBILE-TECHNOLOGY-TESLA

Tesla CEO Elon Musk uses his mobile device as he sits in the car arriving to the construction site for the new plant, the so-called "Giga Factory", of US electric carmaker Tesla in Gruenheide near Berlin, northeastern Germany. - The site still has only provisional construction permits, but Tesla has been authorised by local officials to begin work at its own risk. Tesla is aiming to produce 500,000 electric vehicles a year at the plant, which will also be home to "the largest battery factory in the world", according to group boss Elon Musk.
