Dutch designer Daan Roosegaarde is developing an electronic vacuum cleaner that is supposed to suck the smog right out of the air. The technology is being looked at by the mayor of Beijing China, as a potential solution to the smog and air quality in that city. The concept uses buried coils of copper to create an electrostatic field that attracts smog particles, creating a void of clean air above it.
“You can purify the air so you can breathe again,” It creates these holes of 50-60 metres of clean air so you can see the sun again”, said Roosegaarde.
Right now they are only looking at small scale applications, clearing the air over parks and public areas for example. Hopefully in the future this can be implemented on a larger scale but baby steps is what it will take. Hit the link below for the source and interview with Roosegaarde in Dee Zeen.
