Question

This gadget goes on the car window and as the heat increases, the gadget starts exhausting the hot air keeping the car cool. I am not sure how it works but I saw it on TV infomercial about a month ago. Several google searches have not paid off. Please respond if you know of it or anything like it. Texas is HOT and I have a black car.
