The Principle and Potential of the VacTrain
The Concept of the Vacuum-Train or VacTrain was formally described by the world renowned aerospace engineer, Robert Goddard in the early 20th century and patented by his heirs in 1945. It removes the impediments to motion and speed instead of burning more and more fuel to fight them. Rolling resistance (friction) is eliminated with magnetic levitation whilst aerodynamic drag (air resistance) is eliminated by removing the air surrounding the vehicle in a pipe or tunnel. A high efficiency and ultra-fast / supersonic speeds become possible. It is the the only way to achieve fast, sustainable, comfortable, affordable and efficient intercity transportation.
The development of the VacTrain is inevitable. With increasing world population, the emergence of mega-cities, intensifying demand on intercity and transcontinental travel relations as well as with the enormous social, economic, geopolitical and environmental benefits which it will provide, this is only a question of time.
The VacTrain has long been a dream of science fiction. The ongoing Research and Development and its deployment in SwissMetro-NG and in projects in other countries, however, will make it a reality, rather sooner than later.
