Abstract: A hover aircraft employs an air impeller engine having an air channel duct and a rotor with outer ends of its blades fixed to an annular impeller disk that is driven by magnetic induction elements arrayed in the air channel duct. The air-impeller engine is arranged vertically in the aircraft frame to provide vertical thrust for vertical takeoff and landing. Preferably, the air-impeller engine employs dual, coaxial, contra-rotating rotors for increased thrust and gyroscopic stability. An air vane assembly directs a portion of the air thrust output at a desired angle to provide a horizontal thrust component for flight maneuvering or translation movement. The aircraft can employ a single engine in an annular fuselage, two engines on a longitudinal fuselage chassis, three engines in a triangular arrangement for forward flight stability, or other multiple engine arrangements in a symmetric, balanced configuration.

Abstract: A personal refueling station for a personal-sized electric vehicle has a polygonal base structure housing a refueling system and a plurality of flat panels hinged thereto which open to form a flat surface and close up to an upright pyramid for storage. The flat panels have solar PV arrays mounted on their inside surfaces which generate electricity from sunlight in the open position. The electricity is used to generate hydrogen for hydrogen-fuel-cell vehicles, or is stored for recharging non-hydrogen electric vehicles. Alternatively, hydrogen or electricity may be provided from an external renewable power source. The station can also have utility hookups to provide excess hydrogen or electricity to an external energy usage, such as a home, business, or other station. The personal refueling station has a compact design that can be installed at home or business locations. It is designed to accommodate a personal-use electric vehicle such as an electric car or cart or a personal VTOL hovercraft.
