Hyperloop's First Real Test Is a Whooshing Success

Watch the Hyperloop Complete Its First Successful Test Ride
Published on Jul 12, 2017 3min. 16 sec.The Hyperloop is one step closer to becoming a reality. If it works, the new form of transportation could mean a journey from LA to San Francisco city would take just 50 minutes.
Your dream of one day zipping from one city to another in a pod in a pneumatic tube just took one more step toward reality. Hyperloop One announced Wednesday that it successfully tested a full hyperloop.
The step into the future occurred in May at the company’s Nevada test track, where engineers watched a magnetically levitating test sled fire through a tube in near-vacuum, reaching 70 mph in just over five seconds.
That is but a fraction of the 700 mph or so Hyperloop One promises, but put that aside for now. What matters here is all the elements required to make hyperloop work, worked: propulsion, braking, and the levitation and vacuum systems that all but eliminate friction and air resistance so that pod shoots through the tube at maximum speed with minimal energy.
“This is integrating all of the pieces,” says Josh Giegel, Hyperloop One’s engineering chief. “It’s the first phase of a test program that will get us to a production unit.”
Hyperloop One also revealed its design for the pod that will carry the people (or cargo) if and when this thing becomes real. The pod, made of aluminum and carbon fiber, is 28 feet long and resembles a bus.
The May test comes just about a year after Hyperloop One publicly demonstrated its propulsion system on a tube-free track. The addition of that full-scale tube—11 feet in diameter and 1600 feet long—and the engineers’ ability to suck nearly all the air out of it, is a big step, but there’s plenty left to do. For one, they need to master the airlock system that will allow pods to move into and out of the tube without wrecking that vacuum, then spending the time and energy pumping all the air back out.
That addition to the system will come soon after the company reaching its next goal, Giegel says: hitting 250 mph. All the while, the tubers will be working to improve reliability and reduce costs, two crucial elements to solving the riddle that will make all this engineering work seem simple: Building and certifying a system the public and regulators believe is safe, then operating it at profit, in a space already dominated by established, efficient competitors like airlines.
Oh, and it has to beat back rivals like Hyperloop Transportation Technologies, which plans to build systems in Slovakia and South Korea in the next few years, and Arrivo, launched by former Hyperloop One lead engineer, Brogan BamBrogan.
