That’s just a solar-powered low wattage fan. They’d be better served turning it around and blowing hot air out of the interior in my opinion. Not parking in the sun in the first place would be an excellent start, shaded parking spots are the first to go in hot sunny regions, rather than the closest parking spots. You see the cars and trucks scattered across the parking lot huddled around landscaped islands with trees with a barren desert of asphalt in between, lol.
Yes, I know. I mentioned that in the next post.
