Arconic公司的首席材料学家谢丽•麦卡利表示，最令人振奋也最先能实现的项目之一是EcoClean，这是一种能帮助建筑物自我清洁并净化周围空气的特殊涂料，2011年首次问世，与传统的玻璃窗相比有多种好处。

"The functional coating provides aesthetics, it provides maintenance benefits, and it also provides a benefit to the surrounding environment by reducing the content of pollutants around it," she tells Business Insider.

她在接受商业内幕网采访时说：“这种功能性涂料不仅美观，维护起来也方便。由于能减少附近的污染物，对周围环境也有好处。”

EcoClean 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.

EcoClean借助于光线和水汽发挥作用，涂料中混合了可产生自由基的化学物。这些自由基吸收空气中的污染物，并将其分解，与尘垢一起从建筑物外立面丢下，就像清除死皮一样。

The end result is a cleaner building surrounded by cleaner air.

结果就是建筑物和周围空气都更清洁。

Another innovation is in the windows themselves, which Arconic also hopes could be a part of the three-mile-high tower. The new design is called Bloomframe. Essentially, it's a motorized window that converts into an all-glass balcony in under a minute.
