Hyperloop 1 shows off super-speed propulsion technology

The propulsion technology involves levitating pods that use electricity and magnets to move through a low-friction environment at the speed of sound.

A sled speeds down a track during a test of a Hyperloop One propulsion system on Wednesday. The startup company opened its test site outside of Las Vegas for the first public demonstration of technology for a super-speed, tube based transportation system.

A low-profile block of aluminum zipped across a short stretch of what looked like railroad tracks Wednesday before crashing into a tuft of sand and sending a small cloud into the clear skies of the desert north of Las Vegas.

The seconds-long demonstration by startup Hyperloop One marked the first public glimpse of a propulsion system that its creators hope will rocket people and cargo through tubes at the speed of sound in five years.

It took place as hundreds of journalists and investors watched from grandstands about 50 yards away after being bused to the site from a swanky casino.

"It's going to eliminate the barriers we face every day of time and distance. It's going to change our lives," CEO Rob Lloyd said a day earlier. "It's real. It's happening now."

Executives with the Los Angeles-based company said the system could whisk people the 350 miles from Los Angeles to San Francisco in 30 minutes.

They described a future where there's no such thing as a long-distance relationship, and it doesn't matter where you live because the commute to work would be so quick.

They say the tubes could run underground — a safe alternative to highway crossings and inclement weather.

The propulsion technology involves levitating pods that use electricity and magnets to move through a low-friction environment at more than 700 mph.

The idea was first articulated in a paper by Tesla co-founder Elon Musk in 2013. Mr. Musk was busy building his electric car and rooftop solar companies at the time, and offered the idea to whoever wanted to try it out.

The idea has skeptics, including professor James Moore II, director of the University of Southern California's Transportation Engineering Program.

He credited Musk for the new idea on how to move objects through tubes but said backers would face myriad public policy issues before it's installed on a large scale, including questions about safety, financing, and land ownership.

Such roadblocks are keeping self-driving vehicles off the road decades after the idea was born, he said.

"I would certainly not say nothing will come of hyperloop technology," Mr. Moore said. "But I doubt this specific piece of technology will have a dramatic effect on how we move people and goods in the near term."

Hyperloop One hopes to start moving cargo by 2019 and people by 2021. It announced Tuesday that it had completed another $80 million round of financing and was partnering with firms including GE and SNCF, the French national railway company.

Hyperloop One secured land in December in North Las Vegas to test the technology in a desert industrial park and will receive $9 million in state tax breaks for its investments in the state.

Company officials hope to combine the separate components later this year for a test it's calling its "Kitty Hawk moment" – a reference to the Wright Brothers' inaugural airplane flight.

Dear Reader,

About a year ago, I happened upon this statement about the Monitor in the Harvard Business Review – under the charming heading of “do things that don’t interest you”:

“Many things that end up” being meaningful, writes social scientist Joseph Grenny, “have come from conference workshops, articles, or online videos that began as a chore and ended with an insight. My work in Kenya, for example, was heavily influenced by a Christian Science Monitor article I had forced myself to read 10 years earlier. Sometimes, we call things ‘boring’ simply because they lie outside the box we are currently in.”

If you were to come up with a punchline to a joke about the Monitor, that would probably be it. We’re seen as being global, fair, insightful, and perhaps a bit too earnest. We’re the bran muffin of journalism.

But you know what? We change lives. And I’m going to argue that we change lives precisely because we force open that too-small box that most human beings think they live in.

The Monitor is a peculiar little publication that’s hard for the world to figure out. We’re run by a church, but we’re not only for church members and we’re not about converting people. We’re known as being fair even as the world becomes as polarized as at any time since the newspaper’s founding in 1908.

We have a mission beyond circulation, we want to bridge divides. We’re about kicking down the door of thought everywhere and saying, “You are bigger and more capable than you realize. And we can prove it.”

If you’re looking for bran muffin journalism, you can subscribe to the Monitor for $15. You’ll get the Monitor Weekly magazine, the Monitor Daily email, and unlimited access to CSMonitor.com.
