Smog Filter Tower Turns Pollution Into Gems

Every country has its own version of pollution patrol. Bogota has vertical gardens. China has a purification tower. Debuting its most exciting decontamination technology yet, Poland is ahead of the game with a “smog vacuum” that turns dirty air into jewelry.

The tower-like device essentially sucks up smog from the top and then releases the filtered air through its six-sided vents. It can clean more than 30,000 cubic meters of air per hour and uses no more electricity than a water boiler, according to [designer Daan] Roosegaarde.

After three years of research and development, the tower made initial headway in Rotterdam. To encourage other countries to adopt the device, Roosegaarde started pressing collected dust particles into rings and cufflinks. A single gem stone is equivalent to 1,000 cubic meters of air, which sounds like a whole lot, but deceptively so.

“The fine dust that would normally harm us, is collected together with the ions and stored inside of the tower. This technology manages to capture ultra-fine smog particles which regular filter systems fail to do.”

Never did I believe anything remotely attractive could come of city smog. But I like it, and I’m putting a ring on it.

China Builds Air Purification Tower To Reduce Smog

In its last-ditch effort to combat smog with air-purifying bicycles, China has moved onto greater endeavors. Ensuing a promise to plant an Ireland-sized forest, Shaanxi province is tackling air pollution head-on with a giant air purifier.

The system works through greenhouses covering about half the size of a soccer field around the base of the tower.

Polluted air is sucked into the glasshouses and heated up by solar energy. The hot air then rises through the tower and passes through multiple layers of cleaning filters.

Since its recent launch, the 100-meter edifice has produced over 10 million cubic meters of clean air. As one of the most heavily-polluted regions in China, Xian is the perfect guinea pig for purifying technology. The gargantuan spire is still experimental, but may soon swarm the nation.

“It barely requires any power input throughout daylight hours. The idea has worked very well in the test run,” [said head of research Cao Junji.]

Cao’s full-size tower will span 500 meters. If its dwarfed prototype remains as promising as it seems, sunset-gazing in China may just become a popular weekend activity.
