摘要： An electric aircraft includes a forward wing and an aft wing both located on a top side of a fuselage and both having an upward dihedral angle. The forward wing has a straight or slightly forward-swept leading edge. The aft wing has a swept leading edge. A plurality of propeller engines are located on a leading-edge side of the forward wing. A single propeller engine may be located on a top side of an aft end of the fuselage; alternatively, a plurality of propeller engines are located on the aft wing on either its leading or trailing edge. The propeller engines are each powered by an electric motor. An unobstructed cargo door is located on a side of the fuselage, aft of the forward wing.

摘要： An apparatus in which electric power is generated for an electrical load from differentials in electric field strengths within a vicinity of powerlines includes: a plurality of electrodes separated and electrically insulated from one another for enabling differentials in voltage resulting from differentials in electric field strength experienced there at; and electrical components electrically connected therewith and configurable to establish one or more electric circuits whereby voltage differentials cause a current to flow through the established electric circuit for powering the electrical load. Preferably, the apparatus includes a control assembly having one or more voltage-detector components configured to detected relative voltages of the electrodes; and a processor enabled to configure—based on the detected voltages and based on voltage and electric current specifications for powering the electrical load—one or more of the electrical components to establish an electric circuit for powering the electrical load.

摘要： A passenger-carrying rotorcraft with fixed-wings for generating lift utilizes an occupiable structural body, a control unit, a plurality of lift-generating rotors, a portable power source, and a bi-wing structure. The rotorcraft configured with fixed-wings results in an energy-efficient aircraft capable of vertical takeoff and landing. The occupiable structural body is designed to carry a pilot and one or more passengers. The control unit is wired to flight instruments controlled by the pilot, allowing the pilot to maneuver the rotorcraft. The plurality of lift-generating rotors provides upward thrust for vertical takeoff and landing of the rotorcraft. The portable power source is charged by a hybrid power generation system running on both renewable solar energy and a non-renewable chemical fuel source. The bi-wing structure employs two airfoils positioned on top of each other to maximize the lift without significantly increasing the effective wingspan.

摘要： The present invention relates to SMAs (self-moving apparatuses) which use any type of propulsion means, including, without limitation, an FPGB (propeller-gear block) comprising an FP (propeller) and a drive for supplying power thereto. More particularly, the present invention describes: novel forms of energy-efficient (economical) FPGBs; and novel conceptual designs for SMAs, which make it possible to create economical SMAs with high specific power. The invention can be used for creating novel energy-efficient types of SMAs, and for the widespread (mass) use of compact and environmentally-friendly electric engines instead of environmentally detrimental and bulky internal combustion engines.
