In 2013, Elon Musk, CEO of SpaceX and Tesla, unveiled the hyperloop transit system and offered it to the world for free. The system was designed to move people around the country in high speed pods traveling at 800 miles per hour.

Rather than taking his idea and running with it though, many people immediately jumped up to criticize the idea.

“It’s far-fetched … It would be enormously expensive. And I think there are a huge number of technical challenges with the vehicle,” he says. One of the biggest questions is how much energy the system will require. “My questions aren’t could you do it, but could you do it in a way that makes sense from an energy efficiency standpoint and makes sense from an economic standpoint,” says John Hansman, a professor of aeronautics and astronautics at MIT told Technology Review.

“As far-sighted technology evangelism, the Hyperloop is laudable and deserves deeper discussion. As an intellectual idea, or the groundwork for some speculative fiction, it is fascinating. But as a shovel-ready infrastructure project, it is dead on arrival,” said journalist René Lavanchy in a Guardian op-ed.

According to Business Insider, transportation blogger Alon Levy said that the Hyperloop would be a ‘terrifying barf ride’.

So, while many groups have expressed some interest and investigated the idea further it appears that the first person to build a Hyperloop track will be Musk himself.

“Will be building a Hyperloop test track for companies and student teams to test out their pods. Most likely in Texas,” Tweeted Musk on Thursday.

To be clear, it does not appear that Musk is building any kind of transit-pod, merely a track for others to test Hyperloop technology on. Still, having a track to work with could be a huge benefit to groups and engineers attempting to develop the technology.

“We’ll be able to act faster because that big problem is solved,” Dirk Ahlborn told Wired. Ahlborn is CEO of JumpStartFund, a startup based in El Segunda, California. The company, which has brought together 100 engineers from across the United States, is working on developing the Hyperloop into a commercially viable idea. The team also includes 25 graduate architecture students from UCLA who are working on issues such as cost analysis and route planning.

Addistionally Musk said that he was “also thinking of having an annual student Hyperloop pod racer competition, like Formula SAE”.

There is no further word on where in Texas Musk might build the test track, how much it might cost or when construction would begin or end. If all of the details aren’t ready, however, Musk can be forgiven.

It has been a busy couple of weeks for the billionaire.

Last Saturday his company Space X came close to landing a Falcon 9 rocket on a floating platform. Although the landing failed, it came very close and once the system is perfected it will dramatically cut the costs of sending supplies into space.

On Tuesday he was talking about Mars Plans and announcing plans for a Seattle based office for commercial satellite launches. Later, in Detroit, Musk talked to auto industry executives about the short and long term future plans for Tesla Motors. On Thursday he announced a $10 million dollar donation for the study of ethics in artificial intelligence.

As long as he remains this busy, it may take Musk awhile to find a good location for the Hyperloop test track.
