Touring Hyperloop One\'s Ever Evolving Test Site

For the first time since May 2016, the site was opened up to a handful of journalists this week during CES. Hyperloop One was a vastly different company. Back then, it was led by original co-founders Brogan BamBrogan and Shervin Pishevar -- the former quit a few months after an alleged falling out with Pishevar's brother. The latter would depart at the tail end of 2017, departing under a cloud after becoming embroiled in a sexual harassment scandal. In their place, Richard Branson has stepped in as chairperson, rebranding the company as Virgin Hyperloop One.

Another new face is Dr. Anita Sengupta, who has joined the company as the head of its systems engineering division. Sengupta is a veteran of NASA's Jet Propulsion Laboratory and the figure behind the Curiosity rover's supersonic parachute that enabled it to land on Mars. Sengupta's knowledge of theoretical physics will be helpful when it comes to ensuring that the Hyperloop can function safely and reliably. After all, as she says, you don't get to practice landing hundreds of millions of dollars' worth of equipment on another planet.

Her job has been made easier by the fact that DevLoop has now played host to more than 200 test runs of increasing speed and complexity. In November, the company demonstrated that its test pod could reach speeds of up to 240 miles per hour in just a 500-meter long tube. It took a distance of 300 meters to hit that speed, with the following 200 being used for deceleration, fact fans. And even though the tubes have been welded in place, the company continues to make significant tweaks to the system.

There was always a plan to include airlocks in the final design, but engineers were prompted to retrofit one onto DevLoop after a visit to SpaceX's own test Hyperloop. They noticed how very long it took for the tube to depressurize before each run and started building their own airlock shortly afterward. Now a large white box roughly 10 feet tall sits just after the entrance of the tube, which houses a heavy airlock plate that keeps the vacuum separate from the entryway.
