On the picture there is a building that slightly inspired me and convinced me that building like this indeed could be built in RL.
However I have the following question. Could a building like this (but a few sizes bigger, the one on the photo is barely 860m long ;) ) be used to separate industrial district and housing district of a well planed city and stop at least part of pollution? A city where the industrial district is located downwind? Or would such wall actually slow down blowing the pollution away and it would be counterproductive from the perspective of local population?
EDIT: I do not ask about the costs, let's assume that local population would want some high rise residential buildings anyway and in practice its mostly matter of extra cost related to have such building built in specific shape. The question concentrates only on feasibility of using such building to reduce amount of pollution in the housing district from industrial district.
