Abstract:
A system for generating electricity comprising:an air duct disposed within a body, the air duct having an inlet forming an air scoop positioned at the front of the body for receiving air, the air scoop having an axially-narrowing passage, extending rearward, and the air duct having a wind tube in a medial portion of a vehicle in communication with the air scoop and an outlet to the rear of the vehicle in communication with the air scoop, wherein the air scoop further comprises an aerodynamic, axially-narrowing funnel-shaped wall-receptacle for spiraling the incoming air to further increase the velocity of the air passing into the wind tube;a multi-stage impeller system comprising an activation housing having a housing inlet in communication with the wind tube, a housing muffler, a housing passage extending from the housing inlet rearward through the impeller housing to the housing muffler, a high-speed impeller supported within the impeller housing for rotation in response to high velocity air passing through the impeller housing, a low-speed impeller supported within the impeller housing for rotation in response to low velocity air passing through the impeller housing, and means for converting the kinetic energy of the rotating impellers into electricity by means of mechanical energy; andat least one battery disposed within the vehicle, each of the at least one battery electrically connected to, and for charging by, the means for converting the mechanical energy into electricity.
