美公司擬建4800米“抗霾樓”

登上幾百米高的摩天大樓樓頂已經足夠讓人頭暈目眩，你有沒有想過未來可能會在4800米高的大樓裏生活？按美國紐約材料科技公司“Arconic”的設想，到2062年，人類就可以利用3D打印技術製造出能抗霾、淨化空氣的超級摩天大樓。

2017 only just arrived, but one manufacturing company is already looking 45 years into the future.
2017年剛剛到來，但一家制造公司已經在放眼於45年之後的未來了。

Arconic, a materials science company, has envisioned a three-mile-high skyscraper built from materials that are either in-development or have already been brought to market, including smog-eating surfaces and retractable balconies.
材料科學公司Arconic設想出一幢三英里（約4828米）高的摩天大樓。大樓使用的材料全都是正在開發或已經問世的，包括能夠淨化霧霾的外立面和可伸縮的陽臺。

The tower was concocted as part of the company's larger campaign known as "The Jetsons," an homage to the 1962 cartoon set in 2062. Arconic's engineers worked alongside futurists to imagine the technologies that will be most useful several decades from now.
這幢摩天大樓的建造是該公司更大的活動“摩登家庭”的一部分，這一活動是爲了向1962年出品的以2062年爲背景的動畫片《摩登家庭》致意。Arconic公司的工程師與未來學家們一起工作，來設想幾十年後最有用的科技。

Sherri McCleary, one of Arconic's chief materials scientists, says one of the most exciting and immediate projects is EcoClean, a special coating that helps buildings self-clean and purify the surrounding air. It was first released in 2011 and offers a number of benefits over traditional pane glass windows, McCleary says.
Arconic公司的首席材料學家謝麗•麥卡利表示，最令人振奮也最先能實現的項目之一是EcoClean，這是一種能幫助建築物自我清潔並淨化周圍空氣的特殊塗料，2011年首次問世，與傳統的玻璃窗相比有多種好處。

"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.
她在接受商業內幕網採訪時說：“這種功能性塗料不僅美觀，維護起來也方便。由於能減少附近的污染物，對周圍環境也有好處。”

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藉助於光線和水汽發揮作用，塗料中混合了可產生自由基的化學物。這些自由基吸收空氣中的污染物，並將其分解，與塵垢一起從建築物外立面丟下，就像清除死皮一樣。

The end result is a cleaner building surrounded by cleaner air.
結果就是建築物和周圍空氣都更清潔。

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.
另一項發明是窗戶，Arconic公司希望將其用於這幢摩天大樓。這一新設計被稱爲“摺疊陽臺”。這種機動化窗戶可以在一分鐘內變身爲全玻璃陽臺。

Arconic has been showcasing the technology at trade shows around the world and will hit the market in the "near future," a company spokesperson says.
公司發言人稱，Arconic已經開始在世界各地的貿易展覽上展出這一技術，並將在“不久後”推向市場。

Rather than spend twice the money on materials to build separate windows and ledges, Arconic wants to invest in flexible components that can make buildings more than just static giants.
與花費兩倍的錢用於可建造獨立窗戶和窗臺的材料相比，Arconic公司希望可以投資於可用於建築物的柔性構件，而非僅僅是靜態大型結構。

Some of Arconic's other futuristic designs include flying cars, ultra-lightweight car bodies, and aerodynamic airplane wings.
Arconic公司的其他一些未來設計還包括飛行車、超輕量車體、和空氣動力機翼等。

In the meantime, it continues working to push the limits of what modern-day skyscrapers can look like and do. Thanks to 3D printing, McCleary says many structures that aren't currently feasible could withstand high winds and unique climates.
與此同時，該公司還正致力於突破現代摩天大樓外觀和功能的極限。麥卡利表示，由於3D打印技術的應用，目前看來不可行的很多建築結構可以抵抗強風和極端氣候。

"We're looking at optimizing the materials that can be 3D-printed to give more and more options to designers and architects," she says.
她說：“我們正考慮優化可以3D打印的材料，爲設計師和建築師提供更多的選擇。”
