Can jet engines clean up Delhi's foul air?

Wednesday, 14 December 2016 07:00

Sometime next year, if all goes well, a retired jet engine will be mounted on a flatbed trailer and taken to a coal-fired power plant in Delhi.

The engine is thought to have the capacity to generate a nozzle speed of 400 metres per second which is more or less the speed of sound.

The exhaust will create powerful updrafts that will blast the gas from the plant to higher altitudes, where a layer of cold air is held in place by a warmer "lid" trapping smog.

The jet exhaust will have the ability to act as a "virtual chimney", to filter the smog which makes Delhi's air some of the most toxic in the world.

Officials have stated, drones will be utilised before and after the experiment, to capture meteorological data, along with information on frequency of the smog.
