In one of the most polluted cities in the world, a massive ‘vacuum cleaner’ sucks up smog, converts it into clean air, and filters out the smog particles so they can be turned into diamonds.
Dutch artist Daan Roosegaarde was inspired by Beijing smog that he saw from his hotel room blocking his view of the city. Around 42% of smog is made of carbon, and carbon under high pressure forms diamonds. This is gave Roosegaarde another idea for the Smog Free Tower.
“This is not the bright future we envision,” Roosegaarde said. “This is the horror.”
The solar-powered tower has been used in Rotterdam, Beijing, Tianjin and Dalian. It sucks up 30,000 cubic meters of polluted air per hour, cleans it at the nano level and then releases the clean air back into the city.
This tower could pave the way for more that could help reduce the toxic, polluted environments of industrialised cities.
“It’s all about connecting new technology with creative thinking,” said Roosegaarde. “If you start thinking about that, there is so much you can imagine, so much more you can do.”
“Waste should not exist. Waste for the one, should be food for the other,” he said.
