With this design the exiting air is being dumped in to an area with low wind speed so it's meeting resistance there, the back side of the collector that is not facing the wind is seeing a strong negative pressure, most likely sucking a large amount of that moving air back up and out and as redneck pointed out, what do you do when you have high wind speeds?
What about snow, freezing rain, hail, fall leafs?
It's a bad design that looks like the kind of thing a middle school kids came up with.
