China's Smog-Devouring Vacuum Tower Looks Crazy, But Actually Works

What sounded like a long shot attempt to literally suck some of the suffocating smog out of China's sky is actually working, according to updates on the Smog Free Project, which installed an air-vacuuming tower in a Beijing square.

The tower has been up for over 40 days with China's Ministry of Environmental Protection keeping track of the results. This week, they announced that the air around the tower is 55% cleaner than before, scrubbing 30 million cubic meters of air.
