Abstract: A fusion reactor is provided for achieving ultra-high plasma densities required for achieving clean, neutron-free, fusion reactions. This is achieved by designating the reactor with a linear geometry containing an internal plasma flow duct that converges to a point along its central longitudinal axis surrounded by a diverging containment solenoid with increasing wall thickness that generates an increasing axial magnetic field. This field compresses the plasma to ultra high densities as it is magnetically pulled toward the fusion ignition point by the solenoid's magnetic field gradient. Ignition is achieved by a plurality of high power phased-coherent laser beams converging to the ignition point. A secondary solenoid is mounted around the ignition point that magnetically deflects and focuses the ionized reaction products into a directed beam of high energy charged particles which is fed into an MHD generator thereby converting the fusion power of the reactor directly into electric power.

Abstract: A closed-cycle cryogenic engine includes a high specific heat working fluid remaining in a gaseous phase. The high temperature heat reservoir is the natural environment and the low temperature heat reservoir is created artificially by evaporating water. Isothermally compressing the working fluid at low temperature by absorbing compression heat by evaporating water extracts heat energy from the environment, converting it into net output. A plurality of serially connected isentropic expanders is interposed with a like plurality of re-heating stages. The temperature difference between the high and low temperature heat reservoirs is a few degrees, allowing expansion operation with low expansion ratios, enabling a large number of expanding and reheating steps Each engine cycle extracts natural heat energy from the environment, converting a large fraction into high density net output work. Very little water, the engine's only fuel, is consumed since evaporating water's latent heat is high.

Abstract: A closed-cycle cryogenic engine is provided for propelling vehicles or generating electricity at high power densities without consuming any working fluid. The engine comprises a working fluid having a high specific heat that remains in a gaseous phase. The high temperature heat reservoir is the natural environment and the low temperature heat reservoir is created artificially by evaporating water. By isothermally compressing the working fluid at low temperature by absorbing the heat of compression by evaporating water, it is possible to extract a large amount of natural heat energy from the environment and convert a large fraction of it into net output work. Since the latent heat of evaporating water is very high, very little water is consumed which represents the engine's only fuel.

Abstract: An automated transportation system for vehicular travel along a roadway is presented. The roadway can be any hard surface that contains an embedded metallic guiderail along its center. A proximity transducer (metal detector) installed under the vehicle, senses the metallic guiderail and sends steering commands to the vehicle's steering actuators to keep the vehicle moving in the center of the roadway directly over the guiderail. Transponders are embedded along the guiderail at selected points for automatic roadway identification, position determination and automatic speed, headway and route selection and automatic traffic control. The system also provides automatic branching and lane changing. The vehicle's control system includes sensors, signal processors, a microprocessor and various power actuators that are connected to the vehicle's steering, braking and accelerator systems. An on-board collision avoidance system using sonic or radar detection means is also provided.
