  • Patent number: 5653175
    Abstract: A 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.
