Air Ink

This lab is capturing pollution and turning it into paint

The company's first line of Air Ink products includes pens, oil-based paints and spray paints. Each product contains pigments made from carbon soot.

The ink is the brainchild of Graviky Labs founder Anirudh Sharma, who describes himself as a chronic inventor. Sharma previously created LeChal, a smart shoe fitted with sensors that help the visually-impaired walk, through gentle vibrations.
