“Hyperloop” travel might sound like a far-fetched idea, but some companies are already building it

Elon Musk made headlines in 2013 when he shared his vision for a “hyperloop” transportation system, where pods would travel supersonic speeds through a nearly frictionless tube. His vision has since evolved from that concept sketch to today, when different companies are already in the process of creating it.

Watch the video above to see how hyperloop is racing toward reality, and what it could mean for the future of travel.
