In 2017, Virgin Hyperloop’s top executives told The Verge they expect to see “working hyperloops around the world… by 2020.” That deadline was later pushed to 2021, the year they believe the hyperloop will be ready for human passengers.
There are still a lot of safety questions that need to be answered, said Constantine Samaras, associate professor of civil and environmental engineering at Carnegie Mellon University. “A hyperloop vehicle will travel much faster than high-speed rail, maybe even reaching 760 mph,” Samaras said in an email. “Maintaining safety at such high speeds is very important, and all of the unforeseen disasters need to be engineered into the system. An earthquake? The vacuum tube breaks? The train somehow punches through the tube? At such high speeds, these events amplify the danger, and so safety has to be paramount.”
