The underlying physics is the Venturi effect
which has an amazing number of practical applications according to that wikipedia page.
I wonder if you could use two or three bottlenecks in series, i.e. a stack, to get an even bigger temperature reduction. It would need more wind pressure which you could arrange with a large scoop.
For years we have opened our garage door as a wind scoop to funnel air through a screen door between the garage and our kitchen/dining area. I am going to have to experiment with adding a bottleneck layer to the screen door.
Other ideas are to cut the opening in the bottom of the bottle as a rectangle on the bottle side so as to make the bottle scoop air from wind parallel to the window plane, and by twisting the bottles make it slightly tunable to wind direction.
I have also seen bottles filled with water used in roofs to provide solar lighting - in this case the bottle neck points upward and the bottle body is down below the roof emitting light.
You could make a lighting/cooling window by combining a rectangular array of intact bottles full of water with necks pointing out with an equal number of chopped bottlenecks pointing in placed so the necks align in the gaps between the full bottles.
You might not even need the outer chopped bottles as the normal ones already provide a constriction in the spaces between them.
At last something useful to do with all the empty two buck chuck bottles
