Atmospheric carbon has the potential to severely disturb or even threaten the entire species — clearly, that’s the biggest airborne threat. And yet, shorter term will identify a much larger threat in the air: particulate matter. Released by power plans, cars (as VW knows quite well), and industrial processes, these tiny particles have been blamed for thousands of deaths per year, especially in densely populated urban areas. Now, a Dutch designer has an innovative bid to address airborne particulates: take them directly out of the air.It’s called the Smog Free Tower, it’s the brainchild of Daan Roosegaarde and a supporting team. Roosegaarde says it draws in polluted air from public spaces and passes it through filters, expelling air that is “75% more clean” than when it went in.

This creates areas around the towers of markedly increased breathe-ability. It can do this for 30,000 cubic meters of air per hour, and even collects the particles into smog “gems” that can be sold (or used as Kickstarter incentives). It works like an enormous air ionizer — it is an enormous air ionizer. It releases positively charged ions into the city air it collects, and these ions attach to the small particles in the air. A negatively charged electrode then draws in these positive ions, and the dangerous particles along with them. Collected particles are pressed into “Smog Diamonds” for disposal, or sale to people who want jewelry they won’t consider wearing in a month.Now, earlier I said that air pollution is a bigger short-term threat than global warming — is that true? So-called climate refugees are going to become a bigger problem in coming decades, but certainly it will take quite some time to reach the levels of human harm currently seen in air pollution. Recent studies have found that as many as three million people die prematurely due to air pollution, every year.

Other research put it in slightly more understandable terms: breathing in downtown Beijing can be as bad for your lungs as a two pack-a-day smoking habit, or about 40 cigarettes. Even if those numbers are greatly overestimated, that’s still a bigger human problem than malaria and HIV combined, two scourges that rightly receive significant investment. It’s not totally clear how much these towers cost, but based on the original Kickstarter campaign it’s certainly within city budgets — probably on the order of $100,000 or so. home air purifiers for moldAnd since the particulate matter is collected out of the filters, they don’t need to be swapped out every time they fill up, keeping the costs of running them relatively low.smooth air cleaner coverThe smog tower obviously isn’t the solution to air pollution — these things could never offset the large-scale pollution of a major world city. electrostatic air cleaner how it works

However, they can create small pockets of lowered smog concentration throughout city. People can walk through these bubbles, reportedly smelling the difference, which could end up being a powerful awareness-building issue. If the stick of the chance to be one of the 0.017% of all people who die from air pollution every year doesn’t work, perhaps the carrot of pleasant air will work.The Smog Free Tower will be a powerful conversation starter, which the issue of air pollution badly needs. That’s why it’s a shame the pilot project is rolling out in places like Rotterdam, rather than somewhere like Beijing or Los Angeles — but given time, we could see pockets of breathable air in metropolises, too.Rather than the screens, sensors, microchips and Big Data typically employed by Smart City designers, Daan Roosegaarde works with a more fanciful tool kit: smog-eating machines, light-emitting plankton and solar-sensitive paint.“When we talk about innovation today, it’s screen-based, but Smart City is not about another app or microchip,” said Mr. Roosegaarde, whose design firm, Studio Roosegaarde, is based in Rotterdam in the Netherlands.

“Big Data is important, but things can go wrong if we only focus on technology and forget to connect with people and to connect people with their environment.”It is that sort of philosophy that led Mr. Roosegaarde and his partners to create the Smog Free Tower, the world’s first outdoor air cleaner. Just 23 feet tall, it looks like a miniature chrome-latticed skyscraper. But inside, a powerful vacuum uses ionization technology to suck up smog, filter out the dangerous particles and release purified air. Mr. Roosegaarde contends that in 36 hours it can eliminate 70 to 80 percent of the impurities in the air from an area the size of a football stadium.The tower was designed by Mr. Roosegaarde, then tested in Rotterdam. But now it is about to take on a much bigger challenge: China’s Ministry of Environmental Protection recently commissioned Mr. Roosegaarde to temporarily install the tower at a public location in Beijing in September to see how well it performs in the catastrophically smoggy air that is choking China’s largest cities.

It will then go on a sort of smog-fighting tour, with related educational events, to four other Chinese cities over the next year.Neither the Chinese nor Mr. Roosegaarde are under the illusion that the tower will make any real difference in China’s overall air quality. Liu Guozheng, deputy director of the China Forum of Environmental Journalists, a part of the environment ministry, said the Chinese would have to undertake a much more ambitious effort to get at the roots of smog. “However, the role of the Smog Free Tower as a warning sign is still very significant,” he said. “It is a reminder of our mission and responsibility to fight against smog issues.”Ma Jun, an environmental activist in Beijing, echoed that view, calling the Smog Free Tower project a form of “performance art” aimed at raising awareness about air pollution.But Mr. Roosegaarde considers it a first step.And aside from whatever effect it has on the environment, the tower is significant for the entrepreneurship it represents.“

This signals how cities are finding new ways to solve problems, paving the way for new ideas from a much more diverse community of entrepreneurs, innovators and citizens,” said Sascha Haselmayer of Citymart, a New York-based consultancy that helps cities solve problems and share solutions.Mr. Roosegaarde said both the Chinese government and his group would monitor the air around the tower, which uses 1,400 watts of electricity per day, roughly that of an electric kettle.One byproduct of the project is as imaginative as the tower itself: The carbon particles extracted from the air will be compressed and sealed in acrylic in the form of rings, cuff links and cubes, and then sold. The proceeds will be put toward the development and construction of more towers.Mr. Roosegaarde, 36, said the keepsakes were offered during a crowdfunding campaign that provided the initial 113,000 euros, or around $125,000, for the tower. Rings were given to people who donated 250 euros. He said he had received preorders for 1,600 pieces, mostly rings, at a comparable price.

The project’s prototype, which was based on existing technology for purification systems in hospitals and parking garages, took two years to develop at a cost of “around a million euros,” Mr. Roosegaarde said. In addition to the crowdfunding, the City of Rotterdam; the Port of Rotterdam; Stichting Doen, a Dutch foundation; and Studio Roosegaarde provided financial support. An early adviser to Studio Roosegaarde was Bob Ursem, a nanoparticles expert at the Delft University of Technology, who devised a method for positively charging particles to extract them from the air.Mr. Roosegaarde said the idea for the Smog Free Tower came about during a 2013 trip to Beijing, when he learned the blanket of smog was so bad that the city’s children could not play outdoors for part of the year.The tower has prompted inquiries from other cities, including Mexico City, New Delhi and Mumbai in India, and Santiago, Chile.The project typifies the Roosegaarde gestalt: technology and social relevance, connectivity and poetry joined together to create a way of experiencing the urban landscape.

“What stories will people tell breathing the cleaner air around the towers?” he said. “In my life, physical experiences changed me, made me look at things differently. My job is to create this atmosphere.”The son of a math teacher, Mr. Roosegaarde grew up in the lake countryside of Nieuwkoop, in the western Netherlands. Then the country boy went urban.“I’m a guy who fell in love with cities and places before girls,” he said. “At 16, it was, ‘Ah, Antwerp.’”After studying art and architecture, he decided to stay in Rotterdam, because it “has the can-do attitude of a harbor city,” he said. “It gives us the context to test ideas and make a mistake.”He opened Studio Roosegaarde, situated in a more than 10,000-square-foot former glass factory near the harbor. It typically employs a team of 15 designers, engineers and support staff members but can grow to as many as 30 as experts are added for specific projects. Apart from the Smog Free Tower, other Roosegaarde projects that are eliciting international interest are the Smart Highway and the Van Gogh Bicycle Path, in collaboration with Heijmans, the Dutch infrastructure services company.
