Abstract: The invention provides an alternative electrical charging system for a vehicle which is at least partially powered by electricity. The system employs a wind driven generator which produces electricity in response to air motion. When the generator is operating, electricity is communicated the battery of the vehicle. Operation of the generator involves a controller that monitors the electrical status of the battery and selectively activates a fan or opens a ducting system communicating with the generator. The controller also, in some embodiments, monitors the motion and the attitude of the vehicle.

Abstract: An airflow electrical generator for a duct system. The electrical generator is located outside the duct. The axle of the electrical generator is vertical to the airflow within the duct allowing the blades of the generator to be pushed downwind along the duct with the airflow. During the “upwind” movement of the blades, the blades pass outside the duct's profile into a closely fitting plenum allowing each blade to travel outside the airflow and all the low-pressure created by the movement of each blade within the plenum to pull the following blade for improved efficiency.
