"Billionaire and entrepreneur Elon Musk is getting more hands-on with the Hyperloop. Musk, who heads up both space transportation outfit SpaceX and electric-vehicle maker Tesla Motors, casually announced via Twitter on Thursday that he's decided to help accelerate development of his vision for near-supersonic tube transportation, first outlined in August 2013. Musk said he will build a five-mile test track for the still-theoretical system for students and companies to use. A possible location would be Texas, he added, where presumably there is plenty of flat land to go around."
