Abstract: One embodiment of a vehicular power generating device for providing electrical power to the vehicle includes an air channel for ducting air within a vehicular compartment and directs the air towards a housing. The housing includes a rotatably attached wheel that rotates when the directed air comes in contact with vanes of the wheel. The wheel is further attached to a generator that rotates conjointly with the wheel. The generator creates electrical energy, which provides electrical power for producing vehicle's motivational force. The generator also supplies electricity to various electrical components of the vehicle.
