1. In an electric motor-driven vehicle having a vehicle body with a front and a rear, and a passenger compartment between the front and the rear of the vehicle body, the vehicle body having a height and a width, and batteries for supplying electrical power to the motor, an improved battery charging system comprising a rotary turbine with turbine blades mounted at the rear of the vehicle body with an axis of rotation generally perpendicular to a longitudinal axis of the vehicle body, the turbine being mounted for rotation behind the passenger compartment, in which the diameter of the rotating turbine extends over most of the height and width of the vehicle body, with means for electric power generation on the vehicle body coupled to the turbine for charging the batteries in response to rotation of the turbine, at least one upper venturi effect tube with an upper air inlet opening facing toward the front of the vehicle body and connected with an extending along an upper portion of the vehicle body for directing an intake of air generated from forward motion of the vehicle body from an upper front portion of the vehicle toward an upper region of the turbine for increasing air pressure within the upper venturi tube and impinging the air under pressure on the turbine blades to rotate the turbine, and at least one lower venturi effect tube with a lower air inlet opening separate from the upper air inlet opening and facing toward the front of the vehicle body and connected with and extending along a lower portion of the vehicle body for directing a separate intake of air generated from forward motion of the vehicle body from a lower front portion of the vehicle toward the turbine for increasing air pressure within the lower venturi tube and impinging the air in a direction and at a sufficient force upon the turbine at a separate location thereon to increase the pressure applied to rotate the turbine over the force of impinging air flow from the upper venturi tube.
