In September, Hyperloop One, whose high-tech tube transportation concept is central to a firm affiliated with billionaire Elon Musk, of Tesla Motors and SolarCity fame, identified a route largely based in Colorado as one of the ten strongest in the world and entered into a public-private partnership with the Colorado Department of Transportation to launch a feasibility study here. An author who promoted a similar concept in a book published fourteen years ago, cheers this development, but he argues that if the system is built above ground, as opposed to employing tunnels, it won’t succeed and could turn into a disaster.
