Virgin Hyperloop has trialled its first ever journey with passengers, in the desert of Nevada. The futuristic transport concept involves pods inside vacuum tubes carrying passengers at high speeds. In the trial, two passengers – both company staff – travelled the length of a 500m test track in 15 seconds, reaching 107mph (172km/h). However, this is a fraction of Virgin’s ambitions for travel speeds of more than 1,000km/h. Virgin Hyperloop is not the only firm developing the concept but nobody has carried passengers before.
