In a city where smog routinely blankets the streets, a Dutch artist has offered an eccentric solution: a 7-meter (23-foot) metal structure that takes in smog and expels cleaner air.

一位荷兰艺术家为时常遭遇雾霾锁城的城市（北京）提供了一个不同寻常的解决办法：一个7米高的金属建筑，能吸走雾霾，放出洁净的空气。

 

Daan Roosegaarde's Smog Free Tower opened recently on a small, grassy¹ lot in Beijing's famed 798 arts district. Comprised of 45 silver plates resembling partially² open window blinds, the tower contains an air-purifying machine that runs continuously with a low hum.

丹·罗斯加德设计的雾霾净化塔近日在北京著名的798艺术区一处小型草地广场亮相。雾霾净化塔由45块银色金属板组成，外形类似半开的百叶窗，塔内有一个连续低噪音运行的空气净化器。
