Another Diwali and yet again the national capital territory engulfed in the pollution reaches on top to become the worst polluted city on the planet for a night. The pollution caused by the emissions coming from the heavy vehicular traffic on the roads is almost doubled or even tripled for a night by the heavy smoke coming from the burning of crackers and fireworks.
The night of October 27th witnesses a lot of heavy emissions which degraded the Air Quality to newer extents to reach higher threats marks, like never before. These are not just written words. In March 2019 Delhi-NCR was positioned as the most dirtied urban communities on the planet by Greenpeace and AirVisual investigation.
However, we cannot blame a single night for the poor figures on Delhi’s Air Quality Index. Vehicular contamination has been one of the significant reasons for the breaking down air quality in Delhi separated from mechanical contamination, and homestead consuming.
According to a survey conducted by the Indian Government’s Data.gov.in, there are more than 21 crore vehicles in India. And, if we want to fight the pollution, then keeping half the vehicles off the road will help curb pollution slightly as there will be lesser carbon emission and still it is not a concrete plan.
While a few activities, for example, the odd-even plan have been taken by the Delhi Government to control the rising air contamination, an IIT Kharagpur designer has discovered an answer that may change Delhi’s air quality.
Debayan Saha, a mechanical architect who comes from IIT Kharagpur, has invented ‘PM 2.5’ that can avert small particles in the vehicle’s fumes from getting blended into the atmosphere. The gadget utilizes magnetism to make the particulate poisons gain weight and fall on the ground instead of mixing in with air.
“The innovation created by us utilizes a mix of electric energy and wave energy to impact the contaminations like PM 2.5 to such an extent that they act like a magnet pulling in other particulate poisons from the encompassing environment to get connected to it. As they grow bigger, they become substantial and tumble off securely on the ground like soil,” said Saha.
These particles are significant air pollutants. PM 2.5 particles are tiny in size and their presence in the air reduces visibility and cause the air to appear hazy when Pm 2.5 levels are elevated. They can enter deep into our lungs and can cause short term health impacts, for example, irritation in eyes, nose, throat and lung disturbance, coughing, the brevity of breath. Apart from this, it can cause other ailments like asthma and coronary illness. A single PM 2.5 device is claimed to diminish air contaminations transmitted by 10 vehicles as told by Saha. The gadget can be installed in any engine vehicle, including a car, a transport bus or truck or some other vehicle.
As of now, Saha is a Global Biodesign student at Stanford University where he constructed the gadget ‘PM 2.5’ as a part of his research. Saha had a regular job associated with management of cars and aviation technology. Be that as it may, he worked during nights chipping away for his own company to make medicinal services & healthcare gadgets.
“From that experience, I took in the estimation of a multifaceted group”, he said. Although the organization at last fizzled, yet the experience stayed, which lead him to the Biodesign course offered at Stanford University.
“I understood that there are such huge numbers of different things past designing required for restorative improvements, such as understanding the administrative pathway and clinical preliminaries,” he says.
This is a short video by the developer to describe the use of ‘-2.5’ & the idea behind it.
Although Debayan’s device will not render a 100% solution to the problem, it will reduce the emission of pollutants to a greater extent. If we sincerely wish to fight this problem, then we need to implement the emission controls activities at a larger scale. Plans like odd-even and pool-travel shall be adopted to reduce the number of vehicles on the street.
