Summer is here. Last year this time we were researching how to make a contraption for low cost cooling. I read a lot on this and my fried (my gym friend, whom we call Bhai )actually made a crude cooler. It contained a pipe in which was kept a pad made of some herbs. This pad was kept wet and air was drawn in to this pipe and forced through the pad. Well, the available fan was not powerful enough to produce any appreciable cooling. Bhai claimed that it cooled some but I think it was a psychological effect. More ideas about using chilled water for wetting the pad, using copper tubing circulating with chilled water attached to the front of the fan etc were considered but before going to any extremes, the monsoons came.
The temp is going up and I am feeling like looking up all those things again :?
