2. The passenger pods float inside giant steel tubes using magnetic pressure
You know those pneumatic tubes at the bank drive-up window that you use to shoot the teller your deposit slip? Imagine that, but big enough to fit a couple dozen passengers, and you've got the right idea. Musk's plan involves using magnets to propel aerodynamic capsules (where the people will sit) through giant steel tubes, sidestepping any friction by keeping it afloat on a constant pressurized cushion of air.
3. Actual pod concepts will be competing on a Hyperloop test track this year
Based on Elon Musk’s track record, you’d be silly to underestimate him. However, it’s pretty wild how close we are to seeing a real, live Hyperloop in action. Just last month, Musk’s aerospace company SpaceX hosted a competition of 120 teams of high school and college students, challenging them to come up with innovative Hyperloop pod designs (MIT took the top spot, by the way). Additionally, the construction of test tracks in California and Nevada is underway, where the students will test their pod designs later this year.
