A FOG-CREATING machine could be a low-cost solution to traffic emissions and other air contamination – even chemical leaks and smoke from forest fires, according to its creators at the University of Alcalá de Henares (Greater Madrid region).
'Counterfog', developed over four years by the team led by Professor José Luis Pérez-Díaz with the help of European Union funding, was presented yesterday (Friday) at the region's air base in Torrejón de Ardoz.
Members of the Armed Forces emergency response unit, who are frequently called in to help tackle major forest fires and other disasters, test-drove the Counterfog machine on chemical and smoke particles.
It works using a pipe or column with a type of sprinkler system which generates fog made from clean water, and its microscopic droplets adhere to toxic particles in the air and force them to drop to the ground or other hard surfaces where they can be easily cleaned up.
Madrid is expected to use it to combat air pollution caused by traffic, one of the city's most pressing issues, and it could lead to a situation where cars no longer have to be restricted from entering the main urban hub.
