Kaala-Soot printer uses polluting carbon particles as printing ink
There is so much pollution around in cities that it is slowly but surely affecting our health. So what can be done to eliminate soot (impure carbon particles resulting from the incomplete combustion of hydrocarbons) and reduce pollution in the air? Make some productive use of this pollution. Anirudh Sharma who works at the Fluid Interfaces Group at MIT Media Lab, at Massachusetts Institute of Technology advised by Prof. Pattie Maes has made a printer contraption that runs on soot from pollution.
The inspiration for such a device came from his visit to India where he saw so much pollution and wanted to make some use of these polluting particles. At the same time he was wondering about the chemical procedures used to make printer ink. Combining these two nostalgic thoughts, Anirudh decided to make a printer that uses soot as its material.
Thus came into existence Kaala-Soot/Pollution Printer which works with HP C6602 Inkjet cartridge coupled with an Arduino. This turns the print cartridge into 100dpi print platform which can be used for basic printing jobs for now. The ink is a mixture of alcohol oil substrate and soot which results in a low tech printer ink that can complete your black and white document printing jobs without a hitch.
A very wise idea indeed that could change the way printing industry makes its printer inks and in a way creates more pollution as this ink is made from chemicals. This method of making printer ink could help in reducing the polluting carbon particles in the air, thereby helping us two-folds over.
