"Virgin Hyperloop One are leading the way in these efforts", he continued, noting that the company is "working on exciting projects in the Middle East, Europe, India, Canada, and the U.S.".
Its tracks use magnetic levitation and the pod glides at airline speeds for long distances. In its announcement today, Virgin Hyperloop One says that it "continues to see a growing demand from governments and the private sector around the world".
"From our airlines to our trains to our spaceline, we have always been passionate about innovation in transport too, especially the development of technology that could transform people's lives", Branson said in a statement. "I was very impressed and now look forward to helping turn this cutting edge engineering into a global passenger service".
'This is just the latest example'.
