Abstract: The present invention provides a passive solar updraft pole system for mitigation of urban air pollution comprising a vertical hollow pole (4) defining an internal airflow channel between one or more air inlet openings (1) and an upper outlet opening (6). One or more conical solar absorber/collectors (8) are externally mounted on the vertical hollow pole (4) in vertically spaced relation to absorb solar radiation (7) and transfer heat to adjacent air. The conical solar absorber collectors (8) define a multi-inlet airflow configuration that induces simultaneous entry of polluted ambient air (2) through the air inlet openings (1). Solar heating generates buoyancy-driven natural convection causing heated air to rise through the vertical hollow pole (4), thereby creating a pressure differential that draws polluted ambient air (2) from street level and discharges the air through the upper outlet opening (6) above a pedestrian breathing zone. Figure 2 on sheet no. 2 of the drawings may accompany the abstract when published.
