In August 2013 Elon Musk, CEO of Tesla Motors and SpaceX, released a 50 plus page white paper that described an incredible high-speed train capable of attaining speeds upwards of 800 mph. Now just two years later there are already plans to see his vision come to life. Hyperloop Transportation Technologies is planning a $100 million, 5-mile test track to be built in part of California’s central valley. The 5-mile mini-loop isn’t near the same scale of Musk’s original vision of a Los Angeles to San Francisco commute in a about 30 minutes, but the smaller loop will provide proof of concept and will be the test to see if a full scale loop is actually viable.
