Ink from Diesel Exhaust from Summer 2018 Challenge Magazine
6 Jul 2018
A group of Indian engineers have invented a filter to convert diesel fumes into ink. Fitted to the generators that are widely used during the regular power cuts that cripple India's electricity supplies, the filters remove 90% of the soot particulates in the exhaust gases. The soot is sold on to ink manufacturers. Chakri Innovation have sold 53 machines to governmental agencies, saving 1,500 billion litres of air from pollution. Over a million people die from atmospheric pollution every year in India.
