A device in your car to provide oxygen when the pollution gets too much for your body to bear, or a compact oxygen cylinder which promises deliverance from choking from the noxious fumes at the Capital's intersections is not the stuff of dreams.The Directorate of Scientific and Industrial Research, Ministry of Science and Technology, is optimistic that such a equipment will be for real. The Air Pollution Control Device has been developed by Delhi-based inventor, Mr Sandeep Jaidka and the United States Government has already granted the inventor a patent.
