Hyperloop One, the Los-Angeles-based company developing the technology, is gearing up to send a 28-foot-long (8.5 meter-long) pod gliding across a set of tracks in a test run in Nevada in the next few weeks, spokeswoman Marcy Simon said. Hyperloop One is working to develop a technical vision proposed by Musk, the founder of rocket maker SpaceX and electric car company Tesla Motors. In 2013, he suggested sending pods with passengers through giant vacuum tubes between Los Angeles and San Francisco.
