Suffering from the hottest summer in recent times, India could consider looking at a cooling innovation designed and deployed in neighbouring Bangladesh. The best thing about this cooler? It needs no electricity.
Like in India, rural homes in Bangladesh too are often made of corrugated tin, which make the heat even more oppressive indoors.
Enter the zero electricity cooler, called the “Eco-Cooler” (video above). It’s nothing but a grid made from half cut out plastic bottles, which can be placed in windows. Hot air enters the open end of the bottle and gets compressed in the bottle’s neck, making it cooler before it passes into the room.
According to the video, the cooler can reduce the temperature in a room by five degree celsius.
