Matt Hope’s Breathing Bike will sport a rear-mounted dust filter which will hook up to a 5,000-volt power generator as well as a fighter pilot helmet that is equipped with a breathing mask. This was concocted in order to combat the nasty air pollution over at Beijing, but how practical is it for everyday use? It certainly looks very different from any of the solutions for the layperson right now, and assuming it can be mass produced without burning a hole in the pockets of users, it does seem to shape up to be a pretty decent addition to any DIY post-apocalyptic-style homemade solutions.
