The last few mornings, when I get up and look out of the window, Tadpole Jun's heart is almost broken.
In the face of such bad weather, you can still close the windows and turn on the purifier at home, however, once outdoors, you can only put on a mask and endure in silence.
However, there is an artsy little man who is unique and has set a swan song to the heavens -
I want to clean up the haze in the outdoors as well!
This handsome handsome little brother named Daan Roosegaarde, let's call him little Dan Dan well. But ...... what's that bag he's holding?
Oh, don't mention it, please take the bag of Beijing haze.
That is to say, Xiao Dandan was originally an artist, nothing to run around the world, make a thing no one can understand, the result is that once came to Beijing, just in time to catch the haze, live to be scared of urine!
He knew that as an artist, it was impossible for him to solve such a huge and serious environmental problem on his own, so he set a small goal first --
to use a large outdoor air purifier to create at least one clean space for people to move around freely. Dandan himself calls it a "clean air bubble".
The purifier is called the Smog Free Tower, or "Smog Tower" as we call it. Smog Free Tower is 7 meters high, the specific working mechanism has applied for a patent is not convenient to disclose, but still can briefly explain the basic principle:
By giving the Smog Free Tower electricity, it will release positively charged cations, these cations will be adsorbed with particles in the air, and then through a negatively charged electrode to the ions and particles together with the attraction of the back to stay in the tower. Every day, the haze tower can purify more than 3,500 cubic meters of air, and to ensure that the purified air is at least 75% cleaner than the rest of the city, really open up, the effect is almost like this:
While the effect is good, but the haze absorber's power is not big, 1700W, and professional hair dryer is almost the same. And, unlike ordinary purifiers that utilize filters for filtration, this ion adsorption filters out ultra-fine smoke particles that can penetrate filters, and the lack of filters means no secondary waste.
Here, some people may want to lol, even if there is no filter, is the adsorption of the haze particles itself is not considered garbage? For ordinary people, this is indeed garbage, but you do not forget, little Dan Dan is an artist!
Since 42 percent of the haze powder is carbon, Dandan squeezed it into an 8.4-by-8.4-millimeter cube under high pressure, sealed it in a clear container, and made it into a ring and cufflinks, which he sold on a crowdfunding site for 50 euros.
Whoever buys such a ring, he says, is donating 1,000 cubic meters of clean air to the city.
So here is also a side note to dispel the rumor that there are news reports that haze absorbers can turn haze directly into diamonds, which is not true! Although the haze powder has a high carbon content, diamonds need to be produced under a variety of harsh conditions such as high temperature and high pressure. Who would honestly produce pencils if a bit of carbon could make diamonds.
Through his own artistic creativity and environmental heart, Dandan quickly got the money he needed on the crowdfunding site, and it was an overachievement - he only wanted to raise 50,000 euros, but people were so enthusiastic that they threw more than 100,000 at him.
Small Dandan knows that the haze absorber is only treating the symptoms but not the root cause, and to cure the haze, it is still necessary to eliminate it from the source. So he didn't take the crowdfunded money to mass produce and sell the haze absorbers, but used the money as travel expenses and took the haze absorbers with him on a round-the-world trip - he wanted to use the haze absorbers to awaken the awareness and confidence of humans around the world to fight against the haze.
Beijing, which inspired his project, was of course not to be left behind, and according to himself, he contacted the mayor of Beijing four times before he was finally able to make the trip. But it's very much put to good use when it comes to China:
"If we can place a haze tower in some public ****ing places, such as places where people like to square dance, it will definitely be welcomed by the public." -- Liu Guozheng, secretary-general of the China Environmental Journalists Association
Hearing this, the mainstay of square dancing, the amazons and rare lords, danced even more vigorously in the hazy days.
News media reported that the haze-absorbing tower is now in Beijing, but where exactly is it? Does this place look familiar to you?
Yes, this is 751 Power Square.
