Electric car maker Tesla officially opened its Gigafactory near Reno.
The massive factory is only about 15 percent complete, and when it’s finished will stretch more than 10 million square feet. That’s about the size of 260 pro football fields, making it one of the largest buildings in the world.
The $5 billion dollar factory will manufacture lithium-ion batteries by 2018. Tesla recently pushed ahead its goal of making 500,000 vehicles per year, after receiving big initial demand for its upcoming Model 3 sedan, which goes on sale next year.
