Taking to the stage at this year's Economist Innovation Awards, Elon Musk of SpaceX let slip a few more choice details about his "Hyperloop" high-speed transportation system that would see commuters travel between Los Angeles and San Francisco in a mere 30 minutes, describing the concept for the first time as a cross between Concorde and railgun.
During a show-stealing acceptance speech, Musk explained that, in order to be worth while, the technology must exceed the merits of existing transport systems by being much faster and cheaper while remaining weatherproof and, "ideally," crash proof. "Ideally, he added again, for tongue-in-cheek emphasis.
Musk further hinted that the Hyperloop transport would leave as you arrived to board, and have to deal with "right of way" issues. It may sound crazy, but there was a time he talked this way about commercial spaceflight and we know how that turned out.
