You need large doses of creativity to come up with truly innovative ideas. And that is what MIT has done once again with Kaalink, a device that captures polluting particles given off by cars and uses them to produce writing ink. The ink generated has been given the name Air-Ink.
The process, which is already being tested in India, is the following: Kaalink is placed on the car’s exhaust pipe so that it captures almost all particles, up to 93%, of the carbon that isn’t burnt in the car’s combustions, and which would normally create high levels of atmospheric pollution.
Although the current version being tested in India requires the intervention of the company Gravinky Labs, who empty the device that users give them to produce the ink product, the idea for the future is for each driver to be able to carry out the process independently.
The estimate is that 29.57 milliliters of ink can be produced in 45 minutes.
