Does it sound like science fiction? YES!, but it's real, and there are smog diamonds to prove it. We know that the air we breathe today is not as clean as it was a while ago, and it is no secret that due to industrialization this has been getting worse as the days go by. We share with you our podcast episode about the article Audioplayer 00:00 00:00 Use the up/down arrow keys to increase or decrease the volume. This is the case of one of the most polluted cities in the world, Beijing, China. The Dutch designer Daan Roosegaarde had the brilliant idea of creating and building a tower like the largest air purifier in the world: “The Smog Free Tower”. smog free tower The Dutchman's idea arose when, during his visit and stay in Beijing, when looking out the window of his hotel he noticed that the smog was so thick that he could not see the city. The project, which was funded on Kickstarter, took about three years of research and development.
Finally, Roosegaarde was able to debut his massive machine in September 2015 in Rotterdam and then in 2016, the Dutchman's team partnered with China's Ministry of Environmental Protection to take the giant air purifier on a tour of other Chinese cities (Tianjin and Dalian, for example) to help clean the air. At the beginning of 2018, it was planned to go to a park in Krakow, Poland. The designer declared war on pollution in China with the "Smog Free Tower." It is incredible how 8-year-old children who live in the city have been diagnosed with lung cancer at their young age, and that as a result Email Marketing List of dirty or contaminated air, it has in turn reduced the hope of residents whose ages range from 15 and 16 years old. “This is not the bright future we imagined,” says Roosegaarde. "This is the horror." smog free tower smog free tower The tower works like a normal air purifier only on a larger scale. The designer, with the support of the Chinese government, installed the 7-meter-high tower in Beijing that cleans the air in its surroundings.
The tower releases a charge of positive ions that attract pollution particles. By charging the Smog Free Tower with a small positive current, an electrode will send positive ions into the air, these ions will bind to fine dust particles. A negatively charged surface, the counter electrode, will attract positive ions inward, along with fine dust particles. The fine dust that would normally harm us is collected along with the ions and stored inside the tower. This technology manages to capture ultra-fine smog particles that regular filter systems cannot. “After the particles are filtered out of the air, they don't disappear, but rather they need a place to settle and we had buckets of that unpleasant material in our study,” said Roosegaarde. The Dutchman's work team planned to throw away said material, but they realized 42% of the particles collected were made of carbon, and what do you get when you compress carbon? You get diamonds, of course. To become dark, square gems, the smog particles filtered by the tower must be compressed for a period of 30 minutes.
