NOVELTY - A pair of air scoops (11), positioned at the front of a vehicle body (V), serve as inlets of the air ducts (10). Each air scoop has a rearwardly and axially narrowing passage (12) that is enclosed by aerodynamic funnel shaped walls. The wind tubes (15) of the ducts connect the air scoops to the multistage impeller system (20) at the vehicle rear.    USE - Also for electric power generation used in other vehicles e.g. vans, trucks, boating vessels, airplanes. Also used in power plants for e.g. residencies, businesses.    ADVANTAGE - Increases efficiency of wind-powered, electricity generation system by using multistage impeller arrangement combined with high and low speed impeller by=pass. Allows start or back up air compressor to be built into system, without using additional air accumulator. Heating grill can be integrated into electric power generation system to prevent ice or snow accumulation in system, as well as prevent debris or other fragments from blocking air ducts of system. Electric power generation system provides, inexpensive, dependable, and effective structure.    DETAILED DESCRIPTION - The air introduced into the ducts from the air scoops run in a spiral path upon hitting the walls of the air scoop passages. The velocity of the air flow from the air scoops to the multistage impeller system is increased by the funnel shaped walls of each air scoop passage. The multistage impeller system has an activation housing (21) that connect a housing inlet to a housing muffler (29), and low and high speed impellers (30,40) that are stored in the housing. Each impeller is rotated by low or high velocity air passed from the wind tubes to the activation housing. The muffler discharges the air from the activation housing to the atmosphere. Electricity generators, connected to a vehicle battery, convert the kinetic energy of the impeller rotation into electrical energy.
