Here’s a recent drone view of Tesla Motors‘ giant Gigafactory battery plant under construction in Nevada.
[ Update: Elon says this is just a fraction of the ultimate size of the facility – Elon Musk on Twitter:
This is not the full Gigafactory, it is just the pilot plant (1/4 size)
Another of Elon Musk’s concepts is being moved forward by Hyperloop Technologies Inc, which will begin building a five mile (8 km) long Hyperloop test track in 2016: Hyperloop Glides toward Reality in California – Navigant Research.
Elon has also proposed a test track in Texas.
