To deliver the Model 3 and its dream of an affordable, yet reliable electric car, Tesla needs the Gigafactory. The complex in Nevada will be used to produce batteries at an unprecedented scale, besting the might of every other factory in the world combined. Before that can happen, however, Elon Musk needs to build the darn place. Fresh footage by Matthew Roberts, shot with a DJI Phantom 3 drone in 4K, shows how far the project has progressed. As expected, there's still a long way to go -- only a handful of the 21 Gigafactory "blocks" have been completed so far. Even so, it's an enormous building that dominates the picturesque desert landscape.
