In what appears to be one of the hottest summers in recent times, a group of innovators from Bangladesh have come up with what appears to be a simple but effective cooling technology, one that needs absolutely no electricity or any other external power source to work at all.
This brilliant invention, the “Eco-Cooler” is the brainchild of a partnership between the advertising agency Grey Bangladesh and Grameen Intel Social Business, a Dhaka based “social business information technology company”.
The Zero Electricity Cooler, as fancy as it sounds, is 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 gets compressed in the bottle’s neck, making it cooler before passes into the room. “After initial tests, blueprints of the Eco-Cooler were put up online for everyone to download for free. Raw materials are easily available, therefore, making Eco-Coolers a cost-effective and environmentally-friendly solution”, says Syed GousulAlamShaon, managing partner and chief creative officer at Grey Dhaka.
According to the developers of the invention, the cooler can help reduce the temperature of a room by 5 degree Celsius.
Grameen Intel Social Business’s deputy GM Abdullah Al Mamun said, “Since most rural homes in Bangladesh are made with corrugated tin, the Eco-Cooler has the power to provide relief to millions of Bangladeshis.”
