No, I'm being genuine. It's theoretical and all, but if you were to put up a windmill in the same spot instead of a tower, it's possible traditional air conditioners would be able to cool the building to the same degree while also providing surplus electricity. It's also possible that you wouldn't, and I don't know the answer. It would also be interesting to compare it in different ways as well, like rather than asking "If a windmill was here" we could ask "The energy removed from the wind by the tower", because that would indicate scalability problems if one windmill was indeed able to cool one building, but maybe 100 wouldn't be able to cool 100. All hypothetical, but air conditioners/heat pumps are actually very efficient, so it's possible an active design could be more efficient than a passive one in this situation. At least, until someone does the math
