‘Khas’ – Pakistani Poor Man’s Air Conditioner is a Heat Relief

It is environment-friendly, cheap and the best alternative to expensive air conditioner the Pakistani layman can afford – the straw cooler from Lahore. It might not be useful during the moisture-laden monsoon days, but can surely give the much needed respite from the scorching heat and a good night’s sleep in the months preceding the rainy season. The technology used is very simple and effective. An exhaust fan is surrounded on three sides by sheets of ‘khas’ – straw – on which the small suction pump sprinkles water from the small water tank at the bottom.
