> The Very High Speed Transit System
> by Robert M. Salter
> Year: 1972
>
> Description of a very high speed transit (VHST) system operating in its own rarefied atmosphere in evacuated tubes in 
> underground tunnels. Most cases considered took less time to go coast-to-coast (e.g., 21 min) than it takes an 
> aircraft to climb to an efficient operating altitude. VHST's tubecraft ride on, and are driven by, electromagnetic 
> (EM) waves. In accelerating, it employs the energy of the surrounding EM field; in decelerating, it returns most of 
> this energy to the system. Tunnel systems would be shared by oil, water, and gas pipelines; channels for laser and 
> microwave waveguides; electric power lines including superconducting ones; and freight systems. Environmental and 
> economic benefits are substantial, and the technology for building and operating the system exists.

> Trans-Planetary Subway Systems
> A Burgeoning Capability
> by Robert M. Salter
> Year: 1978
>
> Describes a subway concept called "Planetran" comprising electromagnetically supported and propelled cars traveling 
> in underground evacuated tubes, able to cross the United States in one hour. 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.
