Early concept art for Tesla's Gigafactory. Tesla Motors Tesla's Gigafactory could change the world.

For those unfamiliar, Tesla describes its massive 5.5 million square-foot Gigafactory as a way to “accelerate the world’s transition to sustainable transportation."

The first Gigafactory, located outside Sparks, Nevada, is an ambitious manufacturing facility that plans to build the batteries for Tesla’s electric cars for the foreseeable future. Tesla wants to build batteries that cost significantly less “using economies of scale, innovative manufacturing, reduction of waste, and the simple optimization of locating most manufacturing process under one roof.”

The Gigafactory is also notable since it will be powered completely by renewable energy, according to Tesla.

Tesla’s first Gigafactory aims to start building battery cells by 2017, reaching full capacity by 2020. But for now, all we can do is view the Gigafactory from the outside. And thanks to a drone pilot and his low-altitude quadrocopter, we can see how construction on the $5 billion building is coming along.
