In the village Daulatdia, Rajbari, Bangladesh there are 28,000 people living without electricity in tin huts. Summers are very hot in Bangladesh with temperatures reaching 113 degrees fahrenheit — so you can imagine how the local community in Daulatdia might experience this heat. Homes are pretty unbearable to live in and the people suffer immensely during the long summer period.
Grey Dhaka, the Bangladesh unit of the American based multinational advertising and marketing agency Grey Group, might have come up with a very clever and simple solution: the world’s first zero electricity air cooler made from cardboard and plastic bottles.
You could even make one yourself, all you need is to find a large cardboard, make holes in it then cut some plastic bottles in halves and attach them into the holes. You then hang it in front of a window.
The logic is that the hot air enters the open end of the bottle and is then compressed at the neck of the bottle, making it slighly colder before it enters into the house.
The device’s inventor, Ashis Paul, told The Hindu: “Bangladesh is one of the poorest countries of the world, where 80% of its population is under the poverty line with no access to electricity, and modern conveniences. Eco-Cooler was designed from day one to be free to make and distribute – using sustainable products that have the lowest environmental impact possible.”
It’s a very simple method using repurposed bottles — so not only do you not need nor waste any electricity, you are also recycling old plastic bottles.
The invention has been proved to reduce temperature by 5 degrees, might sound little to you but it makes a hell of a difference in the unbearabale heat.
So far, more than 25,000 households have an Eco-Cooler in their homes in different parts of Bangladesh.

This might seem like a small invention but it could prove to be a major change for many people all over the world and for the planet. Please consider sharing if you are as impressed as we are!
