IIT Kharagpur Graduate Develops Device To Curb Air Pollution

NEW DELHI: An IIT Kharagpur graduate has invented a device called "PM 2.5" which he claimed when fitted near the silencer pipe in vehicles will curb air pollution.

Debayan Saha ('12), a mechanical engineering graduate from IIT Kharagpur, who has invented the device claims that one car fitted with the device can neutralise the pollution emitted from 10 cars in its vicinity.

"The technology developed by us uses a combination of electric energy and wave energy to influence the pollutants like PM 2.5 such that they act like magnet attracting other particulate pollutants from the ambient atmosphere to get attached to it. As they grow bigger in size they become heavy and fall off safely on the ground like soil," said Mr Saha, who was also a research fellow at AIIMS who worked on air pollution. (Read More)
