The first trial using one of the 8.7-metre passenger pods has now been carried out too. In May 2017, a pod levitated on a separate test track in Nevada for 5.3-seconds and reached 70mph. Virgin Hyperloop One plans to send an 8.5-metre long pod down a set of tracks in Nevada. For Hyperloop, the idea is to lower the air pressure, a job that could be done by regularly placed air pumps.Ī one-mile test track built by SpaceX adjacent to Hawthorne, its California headquarters, has been built, and the first successful trial has been carried out. The original VHST proposed using a vacuum, but there's an inherent difficulty in creating and maintaining a vacuum in a tunnel that will have things like stations, and any break in the vacuum could potentially render the entire system useless. So, like high-altitude flying, there's less resistance against the pod moving through the tunnel, meaning it can be much more energy efficient, which is desirable in any transit system. Hyperloop will be built in tunnels that have had some of the air sucked out to lower the pressure. Musk's Hyperloop will take this to the next level by traveling through low pressure tubes. Current active maglev needs powered tracks with copper coiling, which can be expensive. One Hyperloop proposal, from Virgin Hyperloop One, uses passive magnetic levitation, meaning the magnets are on the trains and work with aluminium track. This is how current maglev trains can achieve super speeds, like the 500km/h maglev train in Japan. ![]()
