Butt air is now being polluted by modern transportation, notably gas-powered automobiles, as well as electrical generators that burn fossil fuels and pour polluting chemical waste into the air.
Many of them burn wood, waste and dung indoors for heating and cooking. The soot released into the air as a consequence is also a climate-changer because, being dark, it absorbs heat.
The new improved technology includes high pressure turbine airfoil advancements that enhance operational reliability, lower maintenance costs and improve fuel burn retention.
