a team of Dutch inventors has unveiled a giant air-cleaning vacuum that they say filters out fine particle pollution from the surrounding air, but this project isn't about art, it's purely about functionality.
"It's a large industrial filter about eight meters long, made of steel... placed basically on top of buildings and it works like a big vacuum cleaner," Henk Boersen of the Envinity Group, the makers of the device, told the AFP.
The device can suck in air from a 300-meter radius and from up to four miles above and can clean 800,000 cubic meters of air an hour. It filters out 100 percent of fine particles and 95 percent of ultra-fine particles, based on prototype tests carried out by the Energy Research Centre of the Netherlands.
All they need now is to build another two dozen coal-fired power plants to run the vacuums.

there isn't a lot that grows in those environments. The more pure the air gets, the more sterile the environment is.
You have it backwards. The air is more sterile because there is nothing growing there not because the env is sterile. Plants and animals shed LOTS of stuff more than you would think. Every 2-3 years I get to water blast the crap off my driveway from the trees I planted. Those areas are desolate because the temperature is too cold for life that we like.
