Elon Musk gave a sneak preview of Tesla's billion-dollar gigafactory that is expected to produce lithium-ion batteries for the company.

Business tycoon, Elon Musk presented the gigafactory to the press last Friday, July 22 located in a desert outside of Nevada. Although some say that the factory doesn't seem to special, Musk and his electric company is banking on the factory to revolutionize transportation in the world, said a report by Mashable.

Tesla built its gigafactory to fulfill the demands for its target 500,000 cars per year. Elon Musk wanted to produce batteries in 2020 that are more than batteries produced in the whole world for the year 2013. "The factory is the machine that builds the machine," Elon Musk, Tesla CEO said in a statement published by Wired.

But Musk wanted to walk the talk. The advanced factory is also in line with Musk's renewable energy advocacy saying that the roof will be covered with solar panels that will power the factory as well.

According to the reports of the press who were able to peek into the gigfactory, there is a prominent gray floor and white walls with red trim inside. Innovative robots will do much of the work inside the factory supervised by human and is also supposed to employ about 6,500 employees.

Batteries are one of the core parts Tesla electric cars and other Tesla products such as power walls; currently, they import batteries from Japanese electronics company Panasonic. Musk believes that this is a cost-effective move to lower the prices of batteries and to speed up the production as well.

"Where the shipping costs start to become significant, the obvious way to combat that is to at least put a Gigafactory on the same continent," Musk said in a statement.

Once completed it will be one of the world's biggest factories and according to plan, it will be powered 100 percent by renewable energy.
