Chinese designer Huachen Xin has created Pollution Ranger and Smog Shade, an installation that monitors and visualizes the air pollution levels in cities, that attaches to the roof of a taxi or Uber car and collects data on pollution levels.
This information is then relayed to Smog Shade, a transparent disc in a circular aluminum frame that darkens and becomes opaque if higher levels of pollution are detected in the city.
Based on this data, they could choose whether they need to move in or out of where they currently live, especially people who have lung diseases.
