A physicist says he can clean the air the same way you get dirt off your car--by washing it. (illustration by Philippe Lechien) |
Physicist Mel Prueitt says about 100 of his patented "air scrubber" convection towers could clean half the air in a place like Los Angeles. (illustration by Philippe Lechien) |
Trouble is, besides blocking views and creating shadows, these overgrown lamp shades would require expansive footprints. (illustration by Philippe Lechien) |
Prueitt has explored the notion of building towers in a range of different heights (computer renderings, courtesy Mel Prueitt) |
Prueitt's towers include one that soars 500 meters. Each employs a fine spray of water droplets that would collect gas pollutants, such as sulfur dioxide and ozone. (computer renderings, courtesy Mel Prueitt) |
