Summary
Surveys large-scale schemes that use solar chimneys to clean polluted urban air, such as venting smog above the boundary layer, releasing water spray from the chimney outlet to wash out particles, and trapping fine particulates with big filters. Compared with conventional methods like spray trucks, the reviewed approaches run continuously, need little upkeep and can also produce electricity.
