Now it seems that things are farther along than anyone thought. In fact, construction of the plant might already be secretly underway in Nevada. This is of course interesting as Tesla hasn't officially announced where the gigafactory will be built. Something called Project Tiger is currently underway east of Reno, and there's a lot of construction workers, heavy equipment, and a heavily guarded fenced barrier around the site. The volume of dirt being moved is 140,000 cubic yards, which matches the gigafactory dimensions given earlier this year by Tesla. Is it possible that Tesla's actually building the gigafactory before even announcing its location? It seems so, yes.
