Tesla’s Gigafactory 1 is near Reno, Nevada, and occupies 1215 hectares (3000 acres). Gigafactory 1 itself takes up 510,000 square metres, roughly the same area 70-odd rugby fields would cover. The factory is less than 30 per cent complete and, once finished, says Tesla CEO Elon Musk, will cover between 1.3 and 1.5 million square metres. That’s 200-odd rugby fields. This video from National Geographic has actor Leonardo Dicaprio talking to Tesla’s Musk about the plant.
