Is this plan similar to the one where my neighbor blows his leaves onto my yard? He's firmly convinced he made those leaves disappear completely, since they aren't a problem for him anymore.
Pretty much the same thing. Did that really happen to you? just wow if he did.

Hello! I am new here. I hope your days are going well.
I think this would be fun to ask. How big and powerful would a fan need to be to blow away smog from a major city like say..New York city or a major city in china since they have the biggest population problem? We are talking about a single big fan powered by eletricity. (Honestly I think the fan needs a power plant of its own.)
What kind of physics are involved in such a monstrosity? how big and heavy would the fan blades need to be?

How big of a fan do we need to blow away city smog?

I can try to answer this the best I can:
I don't know the total volume of air for the whole city of New York. Lets say it was a sunny summers day and not windy since most smog clouds like those conditions the most. Well, you don't have mountains but you have the whole city of New York and their buildings. The actual physical location would be like 2 to 3 miles away from the city? Can't we have size and speed? I guess I would choose size since we need to blow away all that smog in New York city. I guess the smog is average I suppose. I wouldn't think humidity level would have an impact. Since a high pressure is above new york city the humidity should be around..40%? Not sure how those two variacles interact honestly lol
