College Student’s Device Can Turn Polluted Air into Printer Ink

This device doesn’t just suck soot out of the air—it repurposes the stuff as printer toner.

Anirudh Sharma, co-leader of a student-run science lab at MIT, has invented something called Kaala, a device that adds alcohol and oil to polluted air and creates printer ink.

The idea first came to him while channeling childhood memories.
