Tesla has doubled the labor force working on its $5B battery factory in the Nevada desert, aiming to meet demand for its coming Model 3. Now, 1,000 workers build seven days a week on two shifts in an effort to start churning out lithium-ion cells by late 2016. Elon Musk is set to inaugurate the Gigafactory with a media briefing today, followed by an exclusive tour and party for Tesla (NASDAQ:TSLA) customers on Friday.
