泡泡穹顶对付雾霾

 

Orproject, a London-based architecture and design firm, has devised the Bubbles project, a design that envisions massive, balloon-like structures filled with clean air.

 

The vegetation inside the park would produce clean air for those living inside the buildings on the perimeter³ of the bubbles, while also providing a smog-free space for residents to spend time in the faux（人造的） outdoors.

 

Rajat Sodhi, director of Orproject India, spent a year and a half developing the idea with the firm's Beijing team.

 

"The seed of this project was the realisation that in developing countries, especially major cities in India and China, the air quality has crossed unacceptable limits." Mr Sodhi explains.

 

"You really can't step out and be outdoors. You just move from one air-conditioned space to another."

 

The group decided⁴ to design the large domes using patterns found in nature.

 

"If you look at the structure of a butterfly wing or that of a leaf, it has a dense⁵ pattern that allows the structure to be fairly stable and fairly large but using very little material," Mr Sodhi says.
