“It works by creating fields of static electricity, attracting or magnetising these tiny dirt particles so you can suck them up,” says entrepreneur Daan Roosegaarde, who came up with the idea for the technology two years ago after seeing six-year-old children in Beijing suffering from lung cancer. Roosegaarde has already built a seven-metre-high version of his tower in Rotterdam, and revealed that authorities in Beijing have purchased the technology and are looking to roll it out across multiple Chinese cities. “The tower we’ve designed at the moment can easily clean the air from a medium-sized park in one day,” he says. “And we can produce bigger ones in the future. Right now it’s just a localised solution, but it can create cleaner public areas and playgrounds, and hopefully it will inspire other designers to come up with technologies which can clean cities on an even larger scale.”
