I added a rooftop self-powered vent fan to the top of my C many moons ago, it uses no power and is nearly silent.
They are often used on tradesman’s vans, especially ones that carry anything flammable (torches, liquids, etc) in the back. You’ve probably seen one and just didn’t realize what it was, they look like a child’s spinning top. The principle is, as you drive, or even a light breeze blows, the exposed spinning top turns, this in turn spins a smaller fan down below the roof which forces air up and out through the top spinner.
It works very well, and uses zero electricity.

Not the same make as the one I used, but the first example I found of a similar product.
