The present invention relates to a ground compaction machine for compacting a ground, in particular a tandem roller, a single-drum roller, a rubber-wheeled roller or a trench roller, comprising a machine frame, at least one travel unit with a wheel or a roller drum, a travel drive for driving the travel unit, and a steering drive for adjusting the traveling direction of the ground compaction machine, the ground compaction machine comprising at least one electric motor. The present invention also relates to a method for operating a ground compaction machine.

An energy storage vehicle includes a solar cell, a power storage equipment, an engine, a transmission module, an electric motor, a pump, a hydraulic motor, a remote control module, and a generator. The transmission module includes an input terminal, a first output terminal, a first clutch, a second output terminal, and a second clutch. The input terminal of the transmission module is driven by the engine. The power storage equipment is configured to store the electrical energy generated by the solar cell and the generator. The power storage equipment is electrically connected to the first electric motor. The hydraulic motor drives multiple wheels of the energy storage vehicle under the control of the remote control module. The remote control module is configured to control the power output of the hydraulic motor and the orientation of the wheels of the energy storage vehicle.

An electrical energy generator system for an aircraft, the system including a streamlined fairing containing at least one turbine housed in the front portion of the fairing, and an electrical energy generator connected to said turbine. The front portion of the fairing is fitted with air admission means that are movable between an open position in which the turbine is exposed to the stream of air outside the fairing and a closed position in which the turbine is masked inside the fairing. The system may serve to reduce the aerodynamic drag caused by turbulence present at a wing tip for a conventional wing having sharp edges during stages of takeoff, climbing, and cruising; and during stages of descent it makes it possible to recover the kinetic and potential energy that has been accumulated by the aircraft during its stages of climbing and cruising.

An aeronautical car includes a ground-travel system including a drivetrain; an air-travel system including a detachable portion configured to house a propulsion device configured to provide thrust and to be driven by the drivetrain when the detachable portion is connected to the aeronautical car, and at least one flight mechanism configured to provide lift once the aeronautical car is in motion; and a weather manipulation device. The weather manipulation device may be configured to manipulate at least one aspect of a weather condition while the aeronautical car is in the air.

Methods and systems for substantially continual electrical power generation for a moving vehicle are disclosed herein. According to the various embodiments discussed herein, the battery range can be increased significantly using a variety of energy sources. The energy sources are configured to facilitate continual electricity generation based on: (i) one or more generators positioned around predetermined vehicle parts; (ii) wind energy created by the motion of the vehicle in relation to the surrounding medium, and (iii) solar energy. The system for continual electrical power generation in a moving vehicle has a generator having a coil-and-magnet arrangement around one or more vehicle components/modified components. The system further has an energy generator for converting solar energy and wind energy into electricity.

When the amount of charge of a temporary battery exceeds a predetermined amount of charge, a solar ECU31 constitutes a charge controller pumps up and boosts power stored in the battery collaborating with a solar charger of a power supply portion, and carries out pumping charge in a main electric storage. While the solar ECU31 carries out the pumping charge, the power supply portion solar charger supplies the generated power from an in-vehicle solar cell to solar ECU31 when the power generated by the in-vehicle solar cell is a predetermined power or less, and supplies the generated power from an in-vehicle solar cell to solar ECU31 and main battery when the power generated by the in-vehicle solar cell is larger than the predetermined power. Even where the pumping charge is being carried out, the power which the in-vehicle solar cell is continuously generating can be used without being discarded futilely.
