A cryogenic condensing system is provided wherein the working fluid is paramagnetic and entropy reduction is accomplished by means of a magnetic field. Condensation is obtained by isentropically expanding partially compressed vapor into a thermally insulated vacuum chamber with a sufficiently large expansion ratio to supersaturate the vapor, a portion of which condenses spontaneously. That portion of the vapor which does not condense is drawn out of the condensing chamber and into the bore of a superconducting solenoid by magnetic attractive forces thereby maintaining the vacuum environment inside the chamber. The noncondensed vapor is magnetized and magnetically compressed inside the solenoid thereby reducing its entropy. Heat of magnetization is extracted by a non-magnetic turbine which converts the kinetic energy of the gas stream pulled into the solenoid into mechanical work. The low entropy vapor is removed from the solenoid by a compressor mounted inside the bore such that its thermodynamic state is returned to the preexpanded state outside the magnetic field. This vapor is mixed with previously condensed vapor having the same thermodynamic state and recycled back through the condensing expander to produce a constant flow of condensed working fluid. The system could be used for cryogenic engines using oxygen.

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 diameter that is accelerated by magnetic repulsive forces generated by a plurality of giant superconducting field coils mounted in underground tunnels. The propulsion dipole is mounted inside a circular hypersonic wing-like structure equipped with movable aerodynamic 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 rapid transit system in which a vehicle, typically comprising a train of detachably coupled cars, is suspended in an underground vacuum tunnel by permanent magnetic rails of high coercivity and propelled by gravity. For closely spaced stations, such as in urban areas, the connecting tunnel paths are smooth continuous curves, lying essentially in the vertical planes connecting adjacent stations. For widely separated stations, such as in inter-city transit systems, the tunnel paths have horizontal reaches at their maximum depth, joined at the ends by smooth paths which arc up towards each station. The magnetic suspension and the vacuum environment enables the vehicle to move frictionlessly at high speeds without contacting the rails or any other part of the tunnel. Gravity propulsion from one station to the next is accomplished by allowing the vehicle to move frictionlessly down the decending arc of the tunnel, during which time it is accelerated by gravity, and decelerating by gravitational braking while moving along the tunnel's ascending arc. Thus, the trip is accomplished by transforming the vehicle's gravitational potential energy into kinetic energy and back into gravitational potential energy. Excess kinetic energy arising from moving between stations having different elevations is supplied or absorbed by onboard linear motor/generators that provide supplementary propulsion or regenerative braking. These linear motor/generators draw and return energy to on-board flywheel energy storage units. While moving along very long straight tunnel paths the vehicle's gravitational coasting speed is boosted by flywheel energy which is recovered by regenerative braking. Since the motion is essentially without friction and since the linear motor/generator-flywheel motor/alternator system can be designed with very high efficiencies, the principle of conservation of energy applies and very little input energy is required. In the ideal case, no input energy would be required since the vehicle's total energy remains constant even while moving between two stations at high speed. When the vehicle is at rest at stations having different elevations, the differences in its gravitational potential energy are balanced essentially by equal differences in its stored flywheel inertial energy. Except for a small amount of electrical energy expended for life support systems and to make up for losses due to energy conversion inefficiences, no energy is used or required for the actual trips between stations.

A battery-operated hand-held multiflash light generator is provided for temporarily blinding an assailant at a distance. The light generator comprises a plurality of high energy storage capacitors, charged by a battery-operated high voltage power supply, and a high intensity flashtube. A high current electronic switch discharges each capacitor through the flashtube thereby generating an intense flash of light. The flash is focused by a reflector to form a concentrated beamed light flash which is aimed at an assailant's head. The intensity of the light flash is sufficiently strong to cause temporary blindness, thereby rendering the assailant immobile. By using discharge capacitors with very high energy storage, and a high intensity flashtube, and a focusing reflector, it is possible to project a light flash several orders of magnitude brighter than the sun. A manual/automatic system is also provided for controlling the brightness. As soon as a capacitor is discharged by generating a light flash, it is automatically recharged a few seconds later. By utilizing a plurality of discharge capacitors, it is possible to project multiple light flashes in rapid fire operation without having to wait for any capacitor to be recharged.

An aerial inflight reloading system and operating method is provided for military combat aircraft using cannon or machine gun ammunition. In this system, a large ammunition carrying aircraft is equipped with an enclosed conveyor fitted with aerodynamic lifting and control surfaces. A controller, positioned in a pod mounted under the rear portion of the aircraft's fuselage, maneuvers the conveyor via flight controls. The conveyor is guided by the controller to a combat receiver aircraft flying behind and somewhat below the supply aircraft, and is connected to a receptacle mounted on the receiver aircraft. After the connection is made, ammunition is transferred from the supply aircraft to the receiver aircraft via the conveyor. The system enables combat aircraft to be reloaded with ammunition while flying close to a combat zone instead of having to return to base to reload. By combining this system with aerial refueling, it will be possible for combat aircraft to spend significantly longer time periods firing on enemy targets before returning to base, thus significantly increasing their operational efficiency.

An electromagnetically propelled space transportation system is provided for transporting passengers and/or freight between the Earth's surface and orbiting spaceports via reusable spaceplanes. Each spaceplane is equipped with a plurality of superconducting propulsion coils extending along its fuselage and is accelerated to orbital velocities inside a vacuum tube by a 1,530 km long electromagnetic linear accelerator. The vacuum tube is evacuated by utilizing the accelerator as a giant vacuum pump wherein a free-moving, magnetically propelled, air-tight piston is driven through the entire tube at low speed thereby forcing the air directly out the end. The spaceplanes are equipped with movable wings and other aerodynamic surfaces that are retracted during launching and extended during landing. The accelerator is capable of launching spaceplanes directly to geosynchronous orbits or onto interplanetary trajectories. The accelerator is embedded deep underground with a maximum depth of 46 km and emerges near the summit of a high mountain. The system is powered by the Earth's gravitational field whereby natural hydro and geothermal energy is converted into electrical energy. Since substantially more electrical energy is generated than is used by the accelerator, the system produces vast amounts of clean renewable electrical energy.

An Earth-based, rapid-fire, electromagnetic accelerator system is provided for launching multiple hypervelocity nuclear or non-nuclear independently targetable warheads on ballistic trajectories to targets located anywhere on or above the Earth's surface. The warheads are mounted inside a reinforced launching sabot containing a plurality of coaxial superconducting dipole magnets. The sabot is magnetically accelerated to hypervelocities inside a large-bore vacuum tube by sequentially exciting a series of driving coils mounted coaxially along the tube. The sabots are injected into the tube from pre-evacuated storage canisters thereby eliminating the need for an air-lock. Terminal guidance systems allow the warheads to be fired over intercontinental distances to hit small, preselected targets with nearly perfect accuracy. The launch velocities are sufficiently high to enable warheads to also intercept and destroy orbiting satellites moving in space high above the Earth's surface.

A traveling-field, magnetic propulsion system and operating method is provided for achieving economical space travel. The system is based upon designing the vehicle in the form of a single-stage streamlined circular toroidal airfoil containing a thin-walled superconducting solenoid. It is initially launched vertically off the earth's surface into a vacuum environment at 125 km using conventional rocket propulsion. It is then accelerated along a high-inclination trajectory by a traveling repulsive magnetic field generated by ejecting an easily ionizable low-density gas cloud in the vehicle's magnetic field and transmitting a high-power, plane-polarized, microwave beam at the cloud tuned to the electron cyclotron resonant frequency. The transmitter is constructed horizontally on the earth's surface as an electronically-steered, phased array several hundred meters in diameter energized by a large superconducting energy storage system. The transmitter will be able to transmit a converging CW microwave beam at the vehicle with very high power to magnetically accelerate it over great distances without atmospheric breakdown. The method can be used as a general high-speed earth or space transportation system by catapulting suborbital or orbital payloads, or by catapulting multikiloton payloads to other celestial bodies with mass ratios below that of long-range aircraft.

An electromagnetic ramjet propulsion system is provided for accelerating high mass payloads through the upper atomsphere at orbital velocities. The propulsion system comprises a plurality of coplaner self-supporting superconducting dipole coils several hundred meters in diameter that is initially accelerated to high altitude and supersonic speed by magnetic repulsive forces generated by a plurality of superconducting field coils several kilometers in diameter embeded beneath the earth's surface. The ramjet is accelerated to orbital velocities by a multigigawatt microwave beam that is transmitted from the earth's surface. A reflecting grid of conducting wires is mounted inside the inner dipole which shock ionizes the low dentisy atmospheric gas passing through it. The frequency of the microwave beam is adjusted to produce electron cyclotron resonance with the free electrons passing through the magnetic field of the dipoles thereby accelerating them away from the dipoles by magnetic repulsive forces, taking the positively charged ions with them. The system becomes a giant hypervelocity ionospheric ramjet propelled by magnetic repulsive forces without any velocity limitations. By utilizing a plurality of microwave transmitters located along the ground track of the ramjet, it is possible to accelerate payloads of several thousand tons to orbit.

A high speed ground transportation system, is suspended in an underground vacuum tube by a frictionless magnetic suspension system and propelled by gravity. The tubes are suspended inside deep underground tunnels from anchor points near each adjacent station and follow smooth catenary curves similar to the main suspension cables of a suspension bridge. Gravity propulsion is accomplished by allowing the vehicle to coast down the descending arc of the tube, during which time it is accelerated by gravity, and decelerating by gravitational braking while coasting up the tube's ascending arc. Thus, the trip is accomplished by transforming the vehicle's gravitational potential energy at one station into kinetic energy and back into gravitational potential energy at the next station. Excess kinetic energy arising from coasting between stations having different elevations is supplied or absorbed by on-board linear motor/generators that provide supplementary propulsion or regenerative braking. These linear motor/generators draw and return energy to an on-board flywheel kinetic energy storage system. Passenger and cargo transfer between the vehicle's interior and station is made without removing the vacuum environment of the vehicle, by providing air-locks through the tube walls at the station.
