Travel from San Francisco to Los Angeles could take just half an hour on the Hyperloop, which is set to break ground in 2016.
The new system would utilize passenger capsules that travel close to the speed of sound, around 750 mph, according to CNBC.
And it could end up being low cost or even free of charge for commuters to ride, despite the projections that it will cost at least $16 billion to build, Hyperloop CEO Dirk Ahlborn told Wired. One way the company could make money other than tickets sales would be to sell its excess renewable energy.
"I really, strongly believe that if we create a hyperloop network and it's free — in the off-peak times at least, in peak times we would charge a little bit — but we make money in other ways, that will really change how people live," Ahlborn said.
Tesla Motors/SpaceX honcho Elon Musk first announced the Hyperloop idea in 2013.
