Watch: Amazing Bangladeshi air conditioner works without electricity and is free!

As much as we crave the rain, it doesn’t look like summer is going away. But in the urban areas, we yet have our fans and air-conditioners to cool us off, but what about those living in rural areas? 

To curb the scorching heat in Bangladesh, Ashis Paul developed a DIY cooling system which does not rely on any electricity and works simply with empty plastic soda bottles. Reportedly, his company has helped install its smart powerless air conditioners, dubbed Eco Coolers in almost 25,000 households.

A report by Observers.France24 explains that developing an Eco-Cooler is easy. One has to simply cut plastic bottles and mount them onto a board and then place it over a window. The bottlenecks should be placed towards the inside of the house.

How does this work?

The report explains, there is a change in pressure that occurs when air enters the wider part of the bottle and comes out through the bottleneck cools the air. The Eco-Cooler can decrease the temperature by 5°C immediately.
