International ClassB60V 001/06AbstractA land transportation system comprising a fully enclosed tubular guideway and a self-propelled air-cushion vehicle disposed in the guideway for providing short and long distance transportation within an enclosed environment. The tubular guideway is secured to stanchions anchored to underground concrete pilings. The air-cushion vehicle includes an internal cavity for receiving passengers and/or cargo holding containers. Air foils, air intake openings and air discharge openings are disposed throughout the cylindrical vehicle to create an air cushion between the vehicle and the guideway, that completely encircles the vehicle, thereby preventing the vehicle from engaging any surface within the tubular guideway during travel. | |
