A simple idea that can go a long way in saving lives in the areas with sweltering summers and shortage of electricity. The system, if installed properly, can reduce the temperature by 5C°. It may not not seem much of cooling but it matters a lot where people actually endure extreme temperatures.
The system is simple to put together with minimum cost. It is a grid made from the 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, when it discharges from the neck it expands and cools down as it enters the room.
This novel idea was brought about by the partnership of Grey Dhaka and Grameen Intel Social Business Ltd., especially for millions of people living in tin shacks.
