Smoke protection wall
Smoke-emitting vehicles around the world pollute the environment a lot. Scientists have come up with a solution in the form of a wall. Which prevents toxic emissions from vehicles coming to the sidewalk and road pollution is limited to the road.
Dr. Tilly Collins of Imperial College, London, first carefully studied the airflow of vehicle emissions and then proposed a special type of wall that would be erected along the sidewalk. Smoke and pollution will not reach the sidewalk, but will hit the curved wall and be confined to the road again. In this way, people traveling on the sidewalk will be able to avoid smoke to a great extent.
