These engineers want to make Elon Musk’s Hyperloop a reality

Nobody laughs much at Elon Musk anymore, but plenty of people snickered at his Hyperloop idea. To remind you, the Hyperloop is a series of underground trains powered by compressed air that transport folks between cities in tubes at around Mach I. While that may sound certifiably insane, a company called Hyperloop Transportation Technologies doesn’t think so, and with the help of some UCLA students, has made considerable progress developing the idea. According to Wired, the startup has enlisted top engineers from companies like Boeing, Airbus and SpaceX willing to work on Hyperloop in their spare time in exchange for stock options.
