It is made of earthen pot with a small fan attached to it. He makes a hole and fixes a pipe.
A small fan is attached on top of it while hay is filled in the pot. When the water run through the hay, it produces cool air.
Everything is inbuilt pot and the power consumed by the pot cooler, even when it is used continuously for 20 hours, is just one unit.
This cooler has zero maintenance. One has to change the cooling pads only once in two years if they are staying in dusty areas. Great!
