It is designed to interface with local transit systems, and the tunnel complex also contains utility transmission and auxiliary freight-carrying systems. Tunnels represent a major problem area and most of the cost. They will be placed several hundred feet underground in solid rock formations. It will require advanced tunnel-boring machines, such as hypersonic projectile spallation, laser beam devices, and the "Subterrene" heated tungsten probe that melts through igneous rocks. Planetran is rated as a system high in conservation of energy. For every car being accelerated, there is one decelerating in an adjoining tube. The decelerating cars return energy to the system. The tubes have a reduced atmosphere, making drag losses much smaller than for aircraft. Coast-to-coast energy costs are expected to be less than $1.00 per passenger.
