Matthew Roberts used a drone to get an idea of the construction going on at the site of Tesla's Gigafactory in Sparks, Nevada. The footage shows off the huge factory, which is the largest building in the world by footprint. Estimates reveal the factory's size has more than doubled over the last half year, putting it at around 4.5 million square feet. Once it's completely finished, it's expected to have a footprint of around 10 million square feet.
Elon Musk's goal behind this factory is to drive down battery costs to new lows to advance the adoption of electric cars as well as home battery storage systems for renewable energy. Tesla claims the Gigafactory will drive down the per kWh cost of their li-ion battery pack by over 30 percent.
The factory will enable Tesla to significantly increase its car production, the project is expected to be completed in 2018 and will produce more li-ion batteries per year than were produced worldwide by all other manufacturers in 2013!
This will not be the only Gigafactory in the world, next year Tesla is expected to announce a second Gigafactory somewhere in Europe. If Musk has his way, many more will follow to transition the world a path of sustainability.
