An electric vehicle with a device, and the device itself, the device capable of converting air currents into electrical energy on board an electric vehicle. The device may be built into the grille of an electric vehicle. A first rotor has a first axis of rotation that is substantially vertical to the direction of travel of the vehicle. At least one inlet includes a first air inlet configured to direct a frontal airflow on the vehicle to a first lateral segment of the internal volume.

Power systems, heat exchanger systems, electrical regeneration systems and air drag reduction systems for a wheeled vehicle are provided. The systems comprise a vehicle that includes a compressed air system and electrical system. The power and drag reduction system also comprises a plurality of pneumatic motors, one each connected to each wheel, the pneumatic motors using compressed air to drive each wheel. The electrical system supports vehicle braking and regenerates electricity for vehicle batteries. A heat exchanger heats expanding air and is configured to substantially evenly distribute said heated air to the pneumatic motors. Air from a front grill is diverted to impellers that turn electric generators to regenerate power and reduce drag. A drag reducing arrangement blending mirrors with camera into the vehicle body is included as is a plug-in 120-volt trickle charge system and a quick charge (DC) system for battery charging.

A capturing wind power system is described that includes a plurality of pipes that extend along the vehicle length and curve towards the rear end of the vehicle. The pipes capture air to help propel the vehicle forward, improving fuel mileage. A cover may be used encase the pipes and allow a rear segment of the pipes to be removed when opening a door at the rear end of the vehicle.

A vehicle has a drive device to move the vehicle and a cooling device to cool the drive device. A duct is arranged to catch air flow striking a front of the vehicle and cool the cooling device with the air flow. A wind power electricity generator is configured to produce power. A control circuit connected to a blanking plate controls the value of the useful cross-section of the duct at least according to an electric power produced by the electricity generator and a speed of the vehicle. The control circuit reduces the useful cross-section of the duct so that the electric power generated by the electricity generator does not exceed a maximum power. The control circuit prevents rotation of the at least one blade when a speed of the air flow in the duct is lower than a threshold minimum speed.

A storage unit capable of being mounted on a shelf on the rear of a vehicle is designed to protrude from the rear of the vehicle to provide more storage space. The storage unit is further designed to be removable, and may be subdivided with movable partitions. The storage unit may be further designed to provide a controlled temperature environment inside. It may be further designed specifically for use on the rear of a golf cart type vehicle, which may include adjustable feet to help hold the storage unit on the rear of the golf cart type vehicle. The storage unit may also be designed to allow for foldability, such that it can be more compactly folded and shipped, stored or transported. There may also be a storage box provided to store the folded storage unit above a vehicle such as a golf cart.

Air channels and wind turbines systems are provided for cooling vehicle parts and storing electrical energy in a vehicle battery. The vehicle may have a battery, a braking system, an air duct with wind turbines and a generator. The air duct has an inlet portion for receiving an airflow, a body portion having wind turbines, and an outlet portion for directing the airflow to the braking system. A generator converts kinetic energy of the wind turbines to electrical energy stored in the battery. The wind turbines can be positioned in an air duct extending from a front bumper to an area proximal to one or more wheels to enhance vehicle aerodynamics. Alternatively, the wind turbines can be positioned in openings between grill shutters to generate energy and cool a radiator. Alternatively, the wind turbines can be positioned proximal to powertrain or drivetrain components for cooling and generating electrical energy.

An improved electrical power-generating system for an electric vehicle powered by at least one rechargeable battery and for a hybrid vehicle powered, at least in part, by at least one rechargeable battery. Each vehicle includes an upper portion and a lower portion spaced from the upper portion. The power-generating system includes a first pair of wind turbines arranged in a first airflow channel located in the lower portion; and a second pair of wind turbines arranged in a second airflow channel in the upper portion. The first and second wind turbines are operatively connected to the at least one battery.

In an embodiment, an energy harvesting apparatus includes a housing, a blade, and a power generation unit, which may include a power generation motor and a piezoelectric power generator. In the energy harvesting apparatus according to an embodiment, electrical energy can be generated by rotation of a blade by a slipstream generated during travel of a mobility vehicle. Electrical energy can be additionally generated by pressure and impact generated during rotation of the blade. When the blade is rotated at high speed as the driving speed of the mobility vehicle increases, pressure and impact can be reduced, thereby preventing damage to the blade or a piezoelectric element and thus improving the durability thereof.

An engine (10) that jets out combustion gas as a driving force is provided. The engine (10) includes a combustion chamber (11), a fuel supplying path (13) that mixes fuel and air and supplies to the combustion chamber (11), an igniter (42) that ignites the mixed gas in the combustion chamber (11), a gas ejecting path (15) that ejects combustion gas (51) from the combustion chamber (11) though a nozzle (18a); and an opening-closing apparatus (80) that opens and closes the gas ejecting path (15). The gas ejecting path (15) is opened by the opening-closing apparatus (80) immediately before ignition, simultaneously with ignition, or immediately after ignition.

An electricity generator includes a wind tunnel positioned on the vehicle. The wind tunnel has an open first end and an open second end. The open first end is in communication with ambient air. A turbine chamber is fluidly coupled to the open second end of the wind tunnel. At least one wind turbine is positioned in the turbine chamber. The at least one wind turbine includes a housing. A rotor is positioned in the housing along an axis that is substantially perpendicular to an axis of the wind tunnel.
