An inventor from M.I.T. has engineered a device, called the Kaalink, to tackle the menacing levels of air pollution in India and other Asian countries. The device, loaded with electronic sensors, mechanical actuators and a collection system, retrofits at the end of a standard automobile exhaust pipe, captures the emitted soot and turns it into printing ink.
Anirudh Sharma, co-founder of Gravinky Labs, and the M.I.T. engineer, who conceived the idea of such a device, describes the Kaalink as a “trash can for your carbon waste,” writes Fast Company Design.
Sharma has collaborated with a firm to launch a line of inks, pens, and artist paints called Air Ink, which has two-fold benefits – this ink rids the environment of deadly air pollutants and also, eliminates the need to burn fossil fuels for the production of ink.
Sharma’s company Graviky Labs claims that each unit, installed by drivers, can absorb carbon for about two weeks of city driving and can then be traded at any of its facilities in India, notes Seeker.
