Envinity Group, a Dutch tech startup has unveiled a giant outdoor vacuum cleaner designed to filter the tiniest toxic specks from the atmosphere. The vacuum cleaner is a large industrial filter about eight metres long, made of steel.
Henk Boersen, a spokesman for the Envinity Group which unveiled the system in Amsterdam said that it could be placed basically on top of buildings. The system is said to be able to suck in air from a 300-metre radius and from up to seven kilometres upwards.
This giant air cleaner could be a new hope for cities like Delhi which are facing severe pollution problem. Delhi government has already decided to install five air purification systems at major traffic intersections to see whether they will make a difference in the quality of the air around.
Another air-purifying system called the Smog Free Tower was installed in Beijing in September and launched by the Dutch artist Daan Roosegaarde.
