If you’re wondering how possible this is, I will like to inform you that it’s true and it’s happening in India. 25,000 household in Bangladesh are living testimonies of this new firm of aircon that requires no form of electricity only some plastic bottles and a piece of cardboard. With summer knocking around, these sets of Indians have taken the initiative to make sure they are comfortable when the time comes for summer. They created an Eco-Cooler– a DIY cooling system that can fit in any window. Bangladesh is only a product of Grameen Intel, a social business information technology and Grey Dhaka an advertising agency, who took it upon themselves to develop this project.
It is understood that 70 per cent of the population in Bangladesh live in huts which increases their chances of not having the opportunity to get electricity in an environment where temperature can reach about 115 degrees Fahrenheit.
This Eco-Cooler is said to believe that it can reduce at least a temperature of 9 degrees which can be very refreshing I a hut.
Making the Eco-Cooler is quite simple and flexible to make and only very little is required. To make a homemade cooling system, grab a piece of a heavy duty cardboard and trim it to fit the window of your choice. Next, cut holes in a grid pattern that are large enough for a bottle neck but be sure the cuts are spaced out according to the size of the bottle. Find as many used bottles as you can and the bigger the size difference between the body and the rim, the better, notes Eco-Cooler. Slice along the body of the bottle and cut away the tops of the caps before placing them back on the bottle – this helps fix the bottle into the board. Pushing the cut bottle from the outer side of the board, twist the cap from the inner side and tighten in to keep the bottle in place.
And finally, place the Eco-Cooler in the window with the wide part of the bottles facing outside. Hot air will rush into each bottle, which is pushed to the rim where it starts to expand – this expansion is what cools the air before it enters the room. Find as many used bottles as you can and the bigger the size difference between the body and the rim, the better, notes Eco-Cooler. The Eco-Cooler is quite simple and you can as well try yours in your apartment.
