Abstract

Disclosed is a system to generate and capture wind power on roads. As vehicles move on a road, the vehicle's body pushes air away from the vehicle's path. In the disclosed system, vehicles can be designed or retrofitted with one or more air redirection devices to redirect some or all of this air in one or more particular directions. Wind capture devices are specifically designed and placed to work with the air redirection devices. As redirected air flows into the wind capture device, the wind capture device generates electricity. The generated electricity can be stored locally or placed on an electrical grid for transfer to a remote area.

Generating and capturing wind power on roads

Disclosed is a system to generate and capture wind power on roads. As vehicles move on a road, the vehicle's body pushes air away from the vehicle's path. In the disclosed system, vehicles can be designed or retrofitted with one or more air redirection devices to redirect some or all of this air in one or more particular directions. Wind capture devices are specifically designed and placed to work with the air redirection devices. As redirected air flows into the wind capture device, the wind capture device generates electricity. The generated electricity can be stored locally or placed on an electrical grid for transfer to a remote area.

A wind turbine is a well known wind capture device. At wind farms, wind turbines can be very large devices with turbine blades that are fifty feet in length. In the disclosed system, the wind turbines may be very small such that the wind turbines can be integrated into the road. For example, a six inch tall and six inch wide channel is made down the center of a one lane road. The channel is covered a metal grid similar to a roadway drain or a bridge with a metal grid driving surface. The metal grid prevent vehicle tires from entering the channel space. The wind turbines are placed below the metal grid and inside the channel space. The wind turbines themselves may be three inches tall, five inches wide, and be placed directly under the metal grid. The three inches below the wind turbines may be for water drainage, road debris, electrical wiring, and the electrical transmission line. Ideally, the wind turbines should be wired such that if one wind turbine fails, the remaining wind turbines can continue to generate and store electricity. On a given fifty foot road, there may be one wind turbine each and every foot down the center of the road.

Vehicle wings, spoilers, and scoops are well known air redirection devices. These devices come in various shapes and sizes and can be located on any surface of the vehicle, above or underneath the vehicle. The devices can be used to add or reduce drag and down-force on the vehicle. The devices can be used to redirect a portion or all of the air flowing around a vehicle in one or more directions. For example, a first vehicle has one large input scoop and two airflow output pipes toward the wind capture system. In another example, a second vehicle has two scoops and one airflow output downward angle wing toward the wind capture system. Air redirection devices can redirect air at an optimal direction for use by the wind capture devices. In particular, the air redirection devices c...
