USA TODAY Tesla Motors CEO Elon Musk is taking a next step with one of his favorite pet projects, the Hyperloop tube high-speed transport system. He tweeted Thursday that there will be a Hyperloop test track built in Texas for companies and student teams to test out their transport pods. Later, he followed up with another tweet about an annual pod racing competition, which sounds like a cross between the Boy Scout's Soap Box Derby and Star Wars Episode One's epic pod racing scene. (Perhaps the hope is to find a real-life Anakin Skywalker.) Musk, attending a transportation conference, told the Texas Tribune that he expects the test track would be about five miles long. Backers of the idea of a tube that can whiz travelers to their destinations inside of pod, or transport vehicles, as hundreds of miles an hour put out a paper a few weeks ago that outlined the feasibility. They envision the first Hyperloop going from San Francisco to Los Angeles, a project they believe would be far cheaper and more efficient than building a high-speed train. Connecting the two cities by Hyperloop could mean making the 400-mile journey in under an hour.
