British designers appear to have had India's pollution-ridden cities in mind for the launch of a revolutionary product that will foreover change the way babies travel: the world's first pollution-proof pram. A special battery-driven fan pumps 160 litres of cleaned air per minute into a protective plastic capsule. Pressurised air inside the bubble prevents outside air from seeping in and a high-tech filter removes pollutants like diesel particles and benzene.
