ABSTRACT:
A Land transportation system has an unmanned mobile box which rides in a tube from one place to another. Guides are affixed to the center of the tube to cooperate with guide rollers on the box to stabilize the running of the box. Wings are provided on the side of the mobile box to provide a buoyancy effect while the box is running, thereby reducing the friction between the box and tube. Additional rollers are placed on the bottom of the box, and come into contact with the bottom surface of the tube when the box is running at slow speeds. The mobile box is driven by linear motor, with the controller for the motor being located outside the tube, and the primary and secondary coils of the motor being located in the tube and on the box. The mobile box also has a signal generator which transmits a prememorized identification signal to a receiver outside the box, to identify destination and other information about the mobile box as it traverses the tube.
