It's a platitude that ideas that do not conform to a narrow expectation or frame of reference are frequently mocked, because some individuals simply can't handle the challenge. That's human nature; too bad. So, this simple gadget is the subject of dumb jokes and the like, but, really it's a good idea.

The PVC mock-up I made at a cost of zero $ is basically a proof-of-concept, and it proved the concept nicely. Some are shocked that anyone would kludge up a sacred 911 coupe by sticking a plastic pipe in the window, but my view is that the silly car is just too hot in summer, and that air conditioning in this car is out of the question. Therefore, the idea is to find a solution and I'm well along on that track.

I like what steely (Dan) said above: "I saw something like that at a German Auto car show (Deutsche Classic) in Fleetwood, PA years ago, and it was vintage then. :-)" That's great - I'm on to a classic idea.

As well, fransdecourt mentioned that a rally car roof vent would also work well. Very true, but it involves serious surgery to the car and I'm not that brave.

So, my first intention is to reduce, or eliminate the longer horizontal portion of the pipe to see how this affects function. Maybe less will even be more. Then, when function is better understood and refined, I'll make an example of the device in copper, which could be a little classier and easier to live with.

The idea is to enjoy the car by creatively seeking solutions to its assorted problems, thereby making the car more agreeable to use. In other words, it's not necessary to bow down to a tightly focused Porsche dogma in order to have fun with the car.
