In one of the world’s most polluted cities, there’s a futuristic tower that sucks up smog, turns it into clean air, and filters out the smog particles so they can be turned into diamonds.
Meet the largest air purifier in the world: the Smog Free Tower.
The tower is in Rotterdam, Beijing, Tianjin and Dalian, sucks up 30,000 cubic meters of polluted air per hour, cleans it at the nano level — the PM2.5, PM10 particles — and then releases the clean air back into the city. (The tower is powered by solar energy.)
It’s incredibly effective: the air around the tower is 55 to 75 percent cleaner than the rest of the city.
The smog particles filtered by the tower are compressed for 30 minutes and turned into dark, boxy gems. The “diamonds” are then used for rings and cufflinks, each representing 1,000 cubic meters of pollution.
