Abstract: Proposed is an eVTOL aerial passenger drone, hereafter referred to as an aircraft, said aircraft comprising an electrically powered fan system, wherein said electrically powered fan system transposes longitudinally- or radially-captured ambient ingress air into at least one tangentially spinning thrust air stream traveling at extremely high outlet/thrust tangential velocities. Said tangentially spinning thrust air stream is corralled from said fan system by at least one volute or entrainment device to a splitter mechanism in order that said thrust air stream can be ejected selectively downwardly, rearwardly, and at an angle between downwardly and rearwardly, for lift and forward propulsion of said aircraft. The electrically powered fan system comprises at least one diagonal fan, preferably at least two diagonal fans in series, and can be additionally used to propel, in an alternative embodiment, a small-to-moderate sized multi-passenger aircraft.

Abstract: A supersonic aircraft comprising longitudinal passenger rows has at its front end a 1st impeller module comprising right and left electrically powered fan sets each comprising two diagonal fans in series, with the respective fan sets spinning in opposite rotational directions around parallel axes. The exhausts from the two fan sets merge to pass conjoined longitudinally along the aircraft to enter a 2nd impeller module comprising electrically powered centrifugal fans rotating in opposite rotational directions around a shared axis. The twin exhausts from the centrifugal fans are collected in specialized volutes that eject the exhausts rearwardly for thrust. All the fans' rotational rates are therefore infinitely variable with thrust always maximized via independent rate modulation of all the fans, few constraints being imposed by airspeed or by prevailing air density.

Abstract: A vehicle propulsion system comprises at least two motors. Combustion occurs upstream of a first motor, and a second motor is downstream of said first motor. The first motor is a turbine that drives a primary propulsion element to effect propulsion and a compressor to effect compression. The second motor is an expansion device whose incoming gases arrive from said first motor. The first motor and the second motor intercommunicate energy via electrical, electromagnetic, and/or mechanical means.

Abstract: An aircraft airfoil or wing or fuselage MODULE is fitted with a gas turbine engine driving a fan or propeller, in combination with a gaseous pressure accumulator, wherein said fan or propeller and said gaseous pressure accumulator both provide thrust, said fan thrust being provided from a rear of the MODULE via a drop-down thrust vectoring panel and said gaseous pressure accumulator thrust being provided from a fore of said MODULE, wherein the gaseous pressure accumulator is supplied with exhaust from said gas turbine engine and said exhaust is delivered downwardly at a variable angle, and said thrust vectoring panel is a panel with multiple minor panels which vector fan thrust at more than one angle. The gas turbine engine exhaust is delivered forwardly of said fan or propeller exhaust.

Abstract: A power plant incorporating attributes of a gas turbine engine, flywheel, and electrical generator (hereafter turbine/flywheel or TF) in a single compact unit, having a compressor arrayed with magnets which weight the periphery of the TF. Intermittent combustion periods accelerate the TF to a first rotational velocity, then combustion ceases, and the inlet/outlet of the TF are sealed, causing it to self-evacuate. Conductive coils surround the TF. Magnetic flux between the magnets and coils acts as a motor/generator, electrically powering a load, and absorbing electrical power therefrom via regenerative braking; power out decelerating the TF (now a flywheel), power in accelerating it. A pressure accumulator accepts the TF exhaust, and is pressurized by the combustion periods. Between combustion periods, exhaust in the accumulator expands in a small pump/motor that drives a generator, routing electricity to the TF to raise its rotational velocity.

Abstract: A floated condenser extracts water from the sky. The condenser is part of or supplemental to a typical buoyed wind turbine set, comprising lift element, wind turbine, retention cable, electrical output, and base. The cable is hollow or coextensive with a lumen, the inner diameter thereof is water impermeable. The hollow/lumen stacks water over an accumulator, effecting a static base pressure p=?gh. This pressure makes the water utilizable. After pressure multiplication—via a hydrostatic piston—or not, a first stream of water electrolyzes into liquid hydrogen and oxygen, one or both stored/sold directly. Another stream of water drives a turbine/motor or series hydroelectric turbines/motors, powering electrolysis and/or grid, the water then stored at moderate pressure for water utilities. Excess power from the wind turbine also supplements electrical output. A conductor runs along the cable. Gasified hydrogen is routed via the cable, lifting the condenser/turbine/kite.
