Elon Musk, co-founder of PayPal, Tesla Motors, and SpaceX, unveiled on Monday the first design for his Hyperloop transit system. Based on his vision and what he tells Bloomberg Businessweek, the new form of transportation would be a solar-powered, city-to-city elevated transit system. Passengers on embark on this 800 miles per hour ride through a steel tube sitting in an aluminum pod. Musk estimates that cost will be between $6 to $10 billion to create the Hyperloop, but believes tickets would be “much cheaper” than traveling on Amtrak. Musk believes that when an investment of this size is made, it should have as significant of returns. He says that the Hyperloop will be safer, faster, lower in cost, more convenient, immune from weather, self-sustaining, earthquake resistent, and “not disruptive to those along the route.” Since the tub would stretch for hundreds of miles, there were some that questioned whether it was realistic.
