Several companies are working to make Elon Musk's Hyperloop transportation concept a reality, including Musk's own The Boring Company. But one of these competitors may have just leaped ahead of the rest.

Arrivo has formed a partnership with the Colorado Department of Transportation to build a Hyperloop-like transportation system in Denver, with a goal of opening it by 2021. But Arrivo's system differs significantly from the Hyperloops detailed in Musk's original white paper, and previewed by multiple companies in renderings and small-scale tests.

First off, the vehicles won't travel in sealed tubes. That should make things easier in emergencies, but it also means pods won't be able to travel in a near-vacuum state and achieve the near-supersonic speeds promised by other Hyperloop developers.
