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.
