Light-weight, durable, land-traversing vehicle 

An automobile, wheeled aircraft or space craft, trailer, hovercraft, snowmobile, sled or other vehicle adapted for travel over land, having strong, light-weight frames that include elongated, vehicle-bracing beams (longitudinal stringers or optionally transverse ribs), having holes in their faces, and sealed bottles or the like, each having a pair of necks (or a neck and bottom) that are strongly glued in opposite holes of a pair of the vehicle-bracing pieces. The holes preferably are sockets, recesses, or depressions that do not extend thru the stringers or ribs. The beams may be of metal, but preferably are of waterproofed "Masonite" or other pressed wood, or of strong, molded or extruded plastic containing sufficient pores or reinforcing fibers for frictional holding of nails, or of cedar, cypress or other wood. Optionally and preferably, the beams are curved in the direction of their length. On their outer and inner edges metal or strong-plastic mesh (preferably expanded-metal lath, hardware cloth and/or poultry-type fencing) is nailed or screwed and/or glued. And on this mesh outer and inner layers of stucco (Portland cement, epoxy or other cement mixed with fine aggregate or fibers) are applied in pasty condition (by troweling or spraying) and allowed to set. Between these stuccoed skins, foamed plastic, from poured-in-situ liquids, imbeds the hollow elements. The vehicle is preferably curved in fore-and-aft direction; optionally it may also be curved vertically (i.e., barrel-curved), in which event, the bottle-holding holes preferably extend entirely thru the beams. The bottle-holding holes may be on each side of each beam and may be staggered, preventing interference of the holes and bottles on the opposite beam sides. Preferably, the vehicle includes: a pair of lateral wheel or runner supports, each having a flat, fore-and-aft inner surface and a curved outer surface; between these surfaces of each support a freely rotating, resiliently mounted wheel or runner; a narrow, streamlined, central, wheel support; and a front steering wheel and a rear driving wheel on the central support. The side wheels or runners ordinarily are clear of the ground, but contact it on sidewise tilting of the vehicle. Lateral and front buffers include foamed plastic and balloons imbedded in the plastic. These and optional other balloons inside the cabin, floating against the top, aid gyroscopic force in preventing tilting of the vehicle.
