Good morning. One should never underestimate the ingenuity of the race, so we won’t. In this case, a Silicon Valley billionaire named Elon Musk has presented the world with the Hyperloop. It is a pneumatic travel route faster than the speed of sound. Its backer is a wunderkind with a proven track record of turning science fiction into reality. Mr. Musk’s CV is impressive, to say the least. He made his initial fortune from PayPal, the online secure payment system, before going on to launch spaceships. Last year his SpaceX venture became the first private operation to dock a cargo capsule with the International Space Station. Hyperlooping. Better than streetcars or subways. (Just kidding).
