Summer is taking its toll here in Mumbai and all over India. Sultry nights are keeping people awake and the flow from the ceiling fan is never enough to cool down the ambient temperature. If at all, the fan seems to circulate a warm flow at the peak of summer. I, for one, found my bed too warm to sleep on. Everyone was turning their attention towards keeping cool and investing a lot on air-conditioners, coolers and the like. But I and Priya, my wife, found a better and a less expensive way to keep our home cool this summer.
