Indian capital opens first 'smog tower' aimed at reducing pollution and purifying the air
The Indian capital opened its first "smog tower" on Monday (August 24) with the aim of reducing air pollution in the city.
The experimental structure is said to be capable of purifying the air in a 1-kilometre radius at a rate of 1,000 cubic meters per second.
Forty fans installed at the bottom of the tower suck air in from the top, filter it and then release it again.
Inside the tower are 5,0000 filters that can collect microparticles included smoke, dust and pollen, according to the project organisers.
A two-year pilot study will ascertain the effectiveness of the smog tower.
