In recent years there has been noticeable competition between architects to create the most sustainable skyscraper. So far there have been buildings admired for their ability to re-purpose rain water, use solar energy, and harness wind power. While these features will continue to be praised for their environmental initiatives, a company called Arconic has pushed the boundaries of what it means to be environmentally friendly even further.

According to Business Insider, Arconic has envisioned a three-mile-high skyscraper that self-cleans, reduces localized air pollution, features retractable balconies and integrates 3D printed materials. 

Arconic proposes using 3D printing to achieve the height of the building, make it more organically-inspired, and able to withstand harsh climates.

To make the building more environmentally friendly, Arconic proposes to use a material called EcoClean which is a special coating that helps buildings self-clean and purify the surrounding air. The material works with help from light and water vapor, which mix with the chemicals in the coating to produce atoms known as free radicals. These free radicals pull in pollutants from the air and break them down to get sloughed off the side of the building along with dirt and grime — almost like dead skin. The end result is a cleaner building surrounded by cleaner air.

In addition to the smog eating capabilities, the building will also feature Arconic's Bloomframe design for windows. This new design of window is motorized and with a push of a button it converts into an all glass balcony in under a minute. Arconic has already developed this technology and has been demonstrating it at various tradeshows.
