International ClassB01B 013/10AbstractA vacuum highway and vehicle system is composed of a cylindrical vehicle structure which travels in an evacuated medium. An electromagnetic propulsion system on the structure is provided for acceleration and deceleration the vehicle along the highway by interacting with magnets on the highway. An electromagnetic rotational stabilization system on the structure also cooperates with the highway magnets to prevent uncontrolled rotation of the structure during travel. The vehicle structure is levitated for travel through the highway by an electrostatic levitation system, which is composed of electrostaticly charged surfaces on the structure and the highway which interact. The surfaces on the highway are segmented to prevent migration of the charge.Field of SearchTUBULAR WAYMAGNETICALLY SUSPENDED CAR Including means to sense or control car position or attitude with respect to guideway Construction or composition of suspension elements Linear motor Propulsion by active guideway; e.g., linear synchronous motor, etc. Including means to control gap Roll control Tubular way | |
