For most of modern history, trains, planes, automobiles, and boats have been humanity’s four main modes of transportation. However, while these vehicles help get us from point A to point B, they’re also costly, harmful to the environment, and generally don’t move quite as fast we’d like. Just recently California moved forward on a $67 billion high-speed rail system in hopes of creating an innovative new way to move large groups of people in significantly less time. Though the project has moved forward, engineer, inventor and Tesla CEO Elon Musk has shared his disapproval alongside his own concept, the Hyperloop, which he claims will be faster and more efficient.

In this episode of Explained, Joshua Smith breaks down what exactly the Hyperloop is, what it means for the future of transportation, and more. Could Hyperloop end up changing the way we get around forever? Check out the video to find out!
