An enclosed tubular continuous mechanical conveying system and method are provided for transporting bulk material or passengers at high speed along straight, curved or twisting paths with unlimited length in three-dimensional space. The conveying medium is a moving endless flexible toroidal surface that is elongated along the direction of motion. The inner surface of the toroid forms a moving enclosed duct that comprises the carrying portion of the surface while the outer portion forms another duct that moves in the opposite direction which encloses the inner duct and comprises the return run of the surface. A rigid, duct-like structure, is mounted inside the moving surface to maintain its shape. The surface is constructed with an elastic material to enable it to move around the rigid inner duct without tearing. The moving surface is mounted inside a rigid protective outer duct which completely encloses the conveyor. Driving means is provided for continuously moving the conveying surface around the inner duct structure. The carrying surface can be supported by a cushion of air trapped inside the toroidal surface or by a magnetic suspension system or by a slider-bed or roller-bed suspension system attached to the rigid inner duct.

A rapid transit system in which a vehicle, typically consisting of a train of detachably coupled cars, is suspended in a vacuum tunnel with at least two sloping reaches from a ferromagnetic monorail of high resistivity by magnetic attraction and propelled by gravity. Servo-controlled electromagnets allow the vehicle to be suspended from the rail without actually being in contact with it or any other part of the tunnel. Propulsion by gravity from one station to the next is accomplished by allowing the vehicle to coast frictionlessly down one sloping reach of the tunnel during which time it is automatically accelerated, leveling off at the horizontal reach at some cruising depth where it coasts along at an essentially constant maximum speed, and then moving up the next sloping reach toward the second station during which time it is automatically decelerated, and finally stopping at the station where the original elevation is reached. When moving from one station to another station at a lower elevation, the excess kinetic energy is recovered by regenerative braking and stored in flywheel alternator-motor energy storage units to be used later in electric motors that enable the vehicle to move from one station to another station at a higher elevation, eventually returning to the original elevation.

A high-speed automated method and operating system is disclosed for constructing continuous-walled tubular structures in space having unlimited dimensions. The system comprises a relatively short tubular conveyor with a flexible endless conveying surface sliding in a longitudinal direction around a smooth cylindrical inner guide tube, and a plurality of wrapping wheels containing wrapping material moving in transverse directions. By moving the conveyor and simultaneously moving the wrapping wheels around the conveyor, sheets of material are wrapped around the outer conveying surface made firm by the inner guide tube to continuously manufacture a rigid multi-layered laminated walled cylindrical structure with an inside diameter equal to the outside diameter of the tubular conveyor. By varying the conveyor speed-to-wrapping wheel speed ratio, any wall thickness is obtained. The wrapping material is rolled into spools, mounted inside cartridges, and loaded into the wrapping wheels for easy insertion and replacement. Thus, the manufacturing process can be continued indefinitely to obtain a tubular structure having any dimensions desired. Since the sheets of wrapping material are transported to orbit in rolls with very high packing density, the machine can construct huge structures in orbit with relatively few trips.

A reusable and regenerative electromagnetic propulsion method and operating system is provided for propelling high mass payloads to orbital velocities which does not require a vacuum environment. The propulsion system comprises a self supporting superconducting dipole coil several kilometers in diamater that is accelerated by magnetic repulsive forces generated by a plurality of giant superconducting field coils mounted in the underground tunnels. The propulsion dipole is mounted inside a circular hypersonic wing-like structure equipped with movable aerodyanmic control surfaces for guidance. The propulsion system can accelerate a payload with any desired launch azimuth by accelerating along a line of magnetic induction generated by the field coils having the desired azimuth angle. The payload is attached to the propulsion system by a plurality of cables. After reaching orbital velocity, the payload is detached from the propulsion system and the propulsion system is decelerated back to the earth's surface by magnetic repulsive forces generated by the field coils. A large fraction of the orbital energy of the propulsion system is reconverted back into electrical energy by the inductive coupling between the magnetically decelerated propulsion coil and the field coils which is used to launch another payload.

A propulsion system for reusable space-based vehicles is presented wherein the propulsive working fluid is atmospheric gas. Acceleration or deceleration propulsion is obtained by expelling or ingesting atmospheric gas respectively. Consequently, propulsive working fluid expelled during accelerating forward propulsive maneuvers is automatically replenished during decelerating retro propulsive maneuvers. The refueling retro thrust is generated by a large diameter hypervelocity has inlet diffuser mounted at the front of the vehicle which scoops up atmospheric gas while traversing through the tenuous upper regions of a planet's atmosphere. The vehicle thereby transfers a portion of its momentum to the collected gas which was initially at rest in the atmosphere. This transfer of momentum generates a decelerating retro thrust by a reverse application of the theory of classical rocket propulsion. The collected gas is condensed, stored on-board the vehicle, and utilized as propulsive working fluid for generating forward propulsive accelerating thrust by expelling the gas at high velocity. The vehicle could operate either as a self-refueling interorbital transfer vehicle or as an interplanetary transfer vehicle moving from planet to planet utilizing each planetary atmosphere as propulsive working fluid.

An economical method for constructing large continuous-walled structures in orbit is presented. In this method a lightweight, non-elastic, topologically closed inflatable surface with thin flexible walls is transported to orbit where it is inflated to form a semi-rigid surface. This inflated surface is then used as a guide for constructing the hull of the structure by wrapping the surface with long sheets of high strength material until the desired wall thickness and rigidity is obtained. The wrapping process is accomplished automatically by a wrapping machine. Since the inflatable surface can be packaged into a small volume, and since the sheets of wrapping material can be rolled into spools with very high packing density, it is possible to construct large continuous-walled pressurized structures in orbit using robotics with relatively few Shuttle flights. The method is used to construct a large permanently manned orbiting space station that provides an artificial gravity environment for the living quarters and connecting variable gravity environments for research and materials processing. The basic structural design of the space station consists of a rotating torus with three connecting spoke cylinders and two Earth-fixed column cylinders extending along the rotation axis mounted on each side of the torus' hub.

A thermodynamic method and engine is provided for extracting natural thermal energy from ambient atmospheric air and converting it into mechanical work. The extraction process is accomplished by isentropically expanding ordinary air at atmospheric pressure into a thermally insulated vacuum chamber maintained at low pressure. By employing sufficiently high expansion ratios, a large portion of the air can be made to undergo a spontaneous phase transformation into the solid state at cryogenic temperature. This results in a substantial reduction of the specific volume of the condensed air which enables the vacuum environment of the chamber to be maintained by expending less mechanical work than that gained from the initial expansion. Thus, the net amount of mechanical work generated therefrom is positive. Substantial additional mechanical work is generated by harnessing the thermal potential difference between the low temperature condensed air and the ambient environment via additional cryogenic engine stages.

The invention described herein is an orbiting solar powered, energy collecting, storage and transmitting station. Initially, a large array of solar cells collects and transforms radiant solar energy into moderate amounts of electrical current. This electrical current is fed into a large superconducting coil where it is gradually built up to very high values. The electrical energy is thereby converted and stored in the resulting magnetic field. This magnetic energy is extracted by drawing off the current at very high rates and used to energize a laser or microwave generator for wireless power transmission. Since the discharge of the superconducting coil can proceed at rates many times greater than the charging rate, the resulting beamed power can, over short time intervals, be many times greater than the rate of solar radiation falling on the solar array. Alternatively, the energy can be stored gradually in rotating flywheels for fast rate beaming.

A hand-held pulsed-light generator is presented for temporarily blinding and assailant at a distance. The light generator comprises a high energy storage capacitor, charged by high voltage power supply, and a high intensity flashtube. A high current electronic switch discharges the capacitor through the flashtube thereby generating an intense flash of light. The flash is focused by a reflector to form a concentrated beam pulse which is aimed at an assailant's head. The intensity of the pulsed-light beam striking the eyes is sufficiently strong to cause temporary blindness, thereby rendering the assailant immobile. By using a discharge capacitor with very high energy storage, and an ultra high intensity flashtube, and a focusing reflector for concentrating the light, it is possible to project a light flash that is several orders of magnitude brighter than the sun. As soon as the capacitor is discharged by generating one light flash, it is automatically recharged a few seconds later for projecting another flash. Rapid fire of several flashes with time intervals of a small fraction of a second is obtained by utilizing a plurality of capacitors, and discharging them serially through the flashtube.
