c. The capsules are separated within the tube by approximately 23 miles (37 km) on average during operation. d. The capsules are supported via air bearings that operate using a compressed air reservoir and aerodynamic lift. 2. Tube: a. The tube is made of steel. Two tubes will be welded together in a side by side configuration to allow the capsules to travel both directions. b. Pylons are placed every 100 ft (30 m) to support the tube. c. Solar arrays will cover the top of the tubes in order to provide power to the system. 3. Propulsion: a. Linear accelerators are constructed along the length of the tube at various locations to accelerate the capsules. b. Stators are located on the capsules to transfer momentum to the capsules via the linear accelerators. 4. Route: a. There will be a station at Los Angeles and San Francisco. Several stations along the way will be possible with splits in the tube. b. The majority of the route will follow I-5 and the tube will be constructed in the median.
