Tesla is making progress on its massive battery cell production facility, the Gigafactory.
Tesla first broke ground on the Gigafactory in 2014 and plans to have it operating at full capacity in 2020. New drone footage shows us how much of the factory is already completed and provides a new level of appreciation for how huge the facility is.

New drone footage shows that a large portion of the factory, which in total will stretch for about 6 million square feet, is already done.
But clearly, there's still some more work that needs to be done. The factory is currently producing battery packs, but will begin producing battery cells in 2017. It won't be fully operational until 2020.
The drone footage really lets you appreciate how massive the Gigafactory is -- those people on the roof look like ants!
And you can also see just how large the campus is. The factory is located on a 3,000-acre plot of land.
'The Gigafactory, when it's complete, will have the biggest footprint of any building in the world. Counting multiple levels it could be as much as 15 million square feet,' Musk said in an an interview with Leonardo DiCaprio for the documentary 'Before the Flood.'
Tesla said the factory will help reduce the price of its batteries by about 30% when it's fully operational in 2020.
But a building this big comes at a price -- Tesla and its partners will invest a collective $5 billion in the factory by 2020.
