I'm not a college professor.
They have Ph.Ds, and supporting colleagues, and the name of a university backing them.
And besides it's probably too simple to patent. A child could do it. To get a patent I think would require some extraordinary innovation. Like louvers that can capture wind from a wide angle, since this would be a static structure and couldn't be turned as the wind changed direction. Personally, I don't think it would require movable louvers, just zippers. Again, too simple, and already patented.
