Air quality in China is bad, it’s really, really bad. The air quality is so poor that residents rarely see the sun and in some cities, the dense air pollution is mistaken for snow! What is causing all of the pollution? It’s coal-burning smog. And until China can ween itself from fossil fuels and implement more sustainable energy practices, other energy solutions are desperately needed. One designer named Daan Roosegaarde may have an ingenius solution.
Roosegaarde has an idea to create what he is calling an “electronic vacuum cleaner”. Copper Tesla coils buried underground would help to create an electrostatic field that would pull smog particles down from the polluted sky, creating a clear space above where sunlight could shine through.
His smog vacuum would attract pollution particles much like a strand of hair is pulled toward a statically charged balloon. Copper coils would create a field of static electric ions which would magnetize the smog, causing it to fall down to the ground below. Roosegaarde plans to capture all of the smog on the ground and compress it, hopefully making it easier to create awareness of how much smog residents are living with and to rally opposition to the causes of the polluted air.
This week Roosegaarde created a working prototype with the help of the University of Delft. They were able to take a 5×5 meter room full of smog and create a smog-free hole of one cubic meter with their device. Now the challenge is how to apply it on a grander scale. Roosegaarde would like to see it installed in parks and public spaces where everyone can enjoy a smog free sky.
Over the course of the next 12 to 18 months, Roosegaarde will be working to perfect his device and many will be watching, waiting, and hoping for his success. Roosegaarde acknowledges that the smog plaguing China is “a human problem not a technological problem” and he hopes that his smog-cleaning vacuum will help raise awareness off the issue while also taking a small step to make the air quality and quality of life a little better for the residents of China.
