Musk projected that his proposed Los Angeles route would cost around $6bn, or $11.5m per mile, compared to $68bn for a high-speed rail link. However, leaked documents from Hyperloop One suggested even a shorter 107-mile loop in California would still cost up to $13bn, or $121m per mile.
Will Hyperloop actually happen?
While the project may seem far-fetched, ventures backed by Musk have gone surprisingly well so far. Plenty of people back the theory behind Hyperloop, which has support from several governments and funding from transport behemoth General Electric and French rail giant SNCF, but the potential cost and feasibility of the technology are still to be tested.
In 2017, Hyperloop One began some of its first tests on the new technology, firing its pod down a 500m test track in Nevada which saw the module reach 70mph in 5.3 seconds.
The company’s lofty ambitions include having three functioning Hyperloop systems in service by 2021. If the developers can keep to their schedule the first Hyperloop could be ready sooner than you think.
