While we wait for a zero pollution world, why not transforming the pollution dust into something useful?
Graviky Labs created a device called “Kaalink” that stops the vehicular soot before it reaches our lungs. The pollution is then transformed into ink. Depending on the type, a 30ML Air-Ink Pen contains 30-50 minutes of air pollution generated by cars. Apparently they have already cleaned 1.6 trillion liters of air so far.
Lately, the ink has been use to create a street art campaign partnering with Tiger beer in Asia.
Ideally, this technology should be applied to all the cars, then the ink could be used to print news papers. (Who else need so much ink?!)
