Coming soon: Pigeon smog blog

Pigeons could track air-pollution in cities and send the information to a blog. The pigeons (apparently very strong) will be loaded up with GPS receivers, carbon monoxide and nitrogen dioxide sensors and a modified mobile phone, as well as a video camera, and will be released at the ISEA symposium A Global Festival of Art on the Edge in San Jose California on August 5. They will transmit air-pollution levels to their blog in real time using SMS messaging. This intriguing project has been devised by artist Beatriz da Costa. link
