Dutch Create Atmospheric Hoover to Suck Up Air Pollution

By Gary Cutlack on at

A team of researchers trying to make the world better and smell less of cars has come up with an interesting idea -- vacuuming the air clean by sticking a giant hoover on the roof of a building.

The range of the thing is said to cover a 300-metre radius from the inlet pipe at ground level, with the cleaning effect somehow reaching up into the sky much better and pulling in particulate matter from up to four miles high. Henk Boersen from maker Envinity Group said: "It’s a large industrial filter about eight metres long, made of steel, placed basically on top of buildings and it works like a big vacuum cleaner."

Which is good news for the UK, as we have a transport secretary who might be interesting in ordering around 6,000 of them to make an airport smell nice. [Guardian]
