Our peculiar image of the week shows a Pigeon Air Patrol that monitors air quality. In March ten pigeons have been released in London, each of them equipped with a tiny backpack. The backpack integrates lightweight pollution sensors by Plume Labs able to measure nitrogen dioxide and ozone concentrations. The analysis of the air quality was then sent back in real-time. Pigeon Air Patrol was the winner of the Twitter campaign #PoweredByTweets, that challenged innovators to think about the potential of objects that are, you guessed it, powered by Tweets.
