Keeping the air inside your car makes a big difference both for the interiors and the people riding in it. This Air Ventilation is a solar-powered fan that keeps the interior of your car cool and fresh. No batteries are needed to run this nifty contraption. Just roll down your window, place the Auto Cool on it, and roll it back up. The solar panels on the outside collect and use the sunlight to run the fan that's on the inside. The fan in the Auto-cool circulates the air that's inside and outside of your car. It sucks out the hot air that's inside your car and replaces it with the cooler outside air so that you can have a healthier atmosphere, inside your car.
