Abstract: A vertical take-off and landing (“VTOL”) aircraft has at least two flying wings (“FW”) with each FW equipped with multiple transverse-radial propellers or a propulsion system for producing a lift force and thrust force on the stationary or non-stationary FW. This VTOL/FWA is capable of exchanging payloads horizontally, as well as vertically, with a stationary or a moving object. In particular, the VTOL/FWA can “walk” on a building wall to adjust and anchor its position in order to rescue people from a high-rise-building window horizontally.

Abstract: This invention presents a unique propulsion and maneuver-control system for crafts and devices. This invention develops its desired thrust force vectors from the vectors sum of centrifugal force vectors of rotating masses and their controlled gyroscopic force vectors. Also shown are applications of this propulsion and maneuver-control system for future VTOL-Hovering-Flying crafts, Scooters, Surfboards, marine/submarine-crafts, earth, moon, mars satellites disks and space-crafts. This invention has great potentials of creating new businesses in aerospace markets, all planets' weather modification business, bring people of the world closer together and perform critical tasks of modify trajectories to prevent run-away asteroids from hitting the earth.

Abstract: A VTOL flying taxicab is provided to solve the ground and airport traffic congestion problems by directing the traffic from two-dimensional ground space to the three-dimensional air space. The VTOL-Flying-Taxicab includes two rows of independently controllable small electrical-motor driven propellers, located above-and-below each of its two wings' leading edges. This configuration divides each wing-top-surface and wing-bottom-surface into independently controllable strips of wing surfaces, where the thrust vector, air velocity vector and air pressure on each and all strips of wing surfaces are independently controllable at any vehicle speed. These features provide all control requirements of the VTOL-flying-taxicab maneuvers.

Abstract: This invention presents a VTOL aircraft with two or more Flying-Wings (FWs), where each FW is equipped with multiple Transverse-Radial propellers capable of producing lift force and thrust force on the stationary or non-stationary aircraft. The aircraft is capable of exchanging payloads horizontally as well as vertically with a stationary or a moving object. In particular, this invention illustrates how this aircraft can “walk” on the building wall to adjust and anchor its position in order to rescue people from a high-rise-building window horizontally.

Abstract: Large wind cones are used to collect and discharge wind energy to small low cost wind turbines. Large straight or gradually bending windcones are installed as sails on top of ships, on anchored floating platforms and on anchored land platforms. Special ship design features to harvest and store harvested wind energy at sea as described. Also presented is a simple low cost design of a small self-azimuth-adjusting wind cone windmill, where the electric generator is located closed to the ground for easy installation and service.

Abstract: A propeller includes a plurality of propeller blades. Each blade has an adjustable drag coefficient. A plurality of actuators adjusts the drag coefficients of the propeller blades. A controlling unit controls the plurality of actuators such that the drag coefficients of each propeller blade is adjusted according to a pattern that is dependent upon the rotational angle of the particular propeller blade so that the drag of each propeller blade is maximized at the same point through a course of revolution and minimized throughout the remainder of that revolution.

Abstract: A Satellite Weather Modification System (SWMS) uses earth satellites to harness solar energy to modify the thermodynamics and composition of the earth's atmosphere. SWMS has three subsystems: The first subsystem includes a network of earth satellites called Satellite Engines (SEs) used to reflect solar energy and/or transform solar energy into other forms of energy beams discharged at specified locations. The media at these locations and the media through which the energy beams pass absorb these energies and change them into heat. The second subsystem includes a large network of Remote Sensing Devices (RSDs). These sensors are used to measure local media compositions, dynamic parameters and thermodynamic properties. Sensor measurements are fed back to the third subsystem, which includes a network of Ground Control Stations (GCSs). GCSs provide energy beam guidance by estimating each beam's characteristics and its aim point trajectory as functions of time.
