We have markers that can blend colors perfectly, and pens that can accurately copy colors from objects in our surroundings. But what if there was some way that we could have an infinite supply of ink and help the environment? Sounds strange and impossible, right? As it turns out, there’s a solution for this.
As odd as it sounds, a company in India (similar to MIT) is proposing this product as a solution to air pollution problems in Asia. What is the proposed solution though? Turning vehicle exhaust into ink. It’s unique and raises a lot of questions, but our knowledge of the product is currently very limited. What we do know, however, is that it involves what they call a “Kaalink“. The Kaalink is attached to the end of the exhaust pipe, and the device then filters and captures unburned carbon emitted from engine combustion.
According to the tests performed thus far, the Kaalink device is able to capture up to 93% of pollution emitted from standard internal combustion engines. That leaves only 7% for planet Earth to deal with! What about the ink itself? How long does it take to get at least an ounce? Here’s where how much you drive will come into play. It takes about 45 minutes of filtration for a single ounce of ink to be produced. So if you’re only driving around town it’s pretty likely you might not get that ounce for a while depending how long you actually have your car running when out and about.
How exactly these captured carbon emissions are processed is under wraps, but it is reported that the captured carbon comes out as high-quality printing ink that can be sold in both the consumer and industrial markets.
Currently the Kaalink devices must be individually, and manually, installed by the vehicle’s driver. Once the device is full, it can then be traded in at the lab in India. It also typically can collect carbon for up to about two weeks before it needs to be swapped out. Again, it would have to be taken back to the labs in India, thus making the availability and convenience rather… restricted. In order to be truly effective, the device also needs to be scaled up to a more significant size as well as become more supported and available in more areas.
Regardless, the idea is still quite valuable.
