Always watch out when buying a printer: the machine itself is cheap, but the ink is very expensive… Printer companies notoriously make a lot of profit selling cartridges. MIT scientist Anirudh Sharma has now found a clever way to turn soot into printer ink. He made a device that can use harmful pollutants and instantly repurpose them into ink, adding a little alcohol and oil. His inspiration comes from his youth in India, when sweaty days would turn your skin black from all the smoke from rickshaws. He thought about a way to harvest this soot and use it for the good. Sharma is still working on ways to perfect his invention. Hopefully, one day we’ll all be able to use it.
