Alphabet, the parent company of Google, has a so-called X division, which works on highly experimental projects. But a lot of these projects could prove very beneficial in solving some of the worldâ€™s biggest problems. This division created Google’s self-driving car, as well as Project Loon, which involves high altitude balloons carrying Wi-Fi.

Cigarette butts are one of the most haphazardly discarded items, and an estimated 766,571 metric tons of them end up deposited into the environment each year across the globe. Furthermore, even if the cigarette butts are disposed of properly, they still pose a threat since arsenic and other harmful chemicals leak from them into the earth and waterways. But now a team of researchers from Seoul National University have found a way to recycle used cigarette filters into super-effective energy storage material. They recently published their findings in the journal Nanotechnology.
