It's called an attic scuttle. What Terracore created is called a whole house fan. I have two that are wired into the house wiring. They are variable speed and on full blast can make the screens whistle. You also need to jam the doors open as they will suck them slammed shut. They're also 25 years old and are undoubtedly dated technology. With a climate that allows a solar version it seems a great idea.
Edit: Some newer ones are ducted into the attic with the fans at the end of the ducts putting the motor further away, thusly quieter. Probably irrelevant with a quiet solar fan. Here in S. Fl a solar version wouldn't suffice much of the year. Nothing besides AC does.
Interesting, at least for me: This YouTube shows one, an invisco (http://invisco.com/products-2/ceiling-mounted-systems/), the author claims is the worlds first infinitely variable whole house fan. Strangely it looks and operates exactly like my 25 year old Emersons.
