Air-Ink is the world’s first ink manufactured from air pollution. It was developed at the MIT Media Lab where they fashioned a device that bolts onto a car’s exhaust pipe to capture outgoing soot. The resulting materials are then processed into an ink and packaged as refillable, water resistant markers and in screen printing ink sets. (Presumably the black and white packaging labels are printed with Air-Ink; it would be a shame if they weren’t.) The claim is that “by using 30 ml of Air-Ink, you can negate 45 minutes worth of pollution.” Its creators are currently raising funds on Kickstarter to bring the products to market, and you can learn more at graviky.com.
