Bangladesh cools down with Eco-Cooler22 July 2016
An innovative project known as Eco-Cooler has developed an inexpensive and electricity-free method to air-conditioning houses in Bangladesh, using little more than plastic bottles and a length of wooden board.
Rural Bangladesh is subject to frequent flooding, which has driven over 70 per cent of the population to live in corrugated tin huts. Most of the residential areas do not have access to electricity, which, in the heat of summer, causes these small huts to become virtual ovens.
Eco-Cooler utilises disposed plastic bottles to create a wind passage that can decrease the temperature inside a room by up to 5 degrees. It works by cutting plastic bottles in half and mounting them onto the grid through bottleneck-sized holes. This contraption is then placed over a window, with the bottleneck facing inward. Wind from outside is directed into the bottles where the bottleneck compresses and cools the air, which is then funnelled into the hut.
Not only free from electricity, this project also makes use of bottles that would otherwise be sent to waste, making it cost-effective and environmentally friendly. The initiative has already been implemented across nearly 25,000 households in villages across the region.
