Zero-electricity air conditioner made with plastic bottles

Posted by Earthr.org Content Team on 20 Aug, 2018

Eco-cooler, a Bangladeshi invention, is a zero-electricity air conditioner that uses repurposed plastic bottles to draw cool air into tin huts. The simple invention consists of halved plastic bottles placed on a board, which is then placed on the wall of a hut.

The bottles' necks compress hot air and cools it down, dropping temperatures inside a hut by as much as 5 degrees. The simple design has already been installed in more than 25,000 homes across Bangladesh, helping to make the unbearable summer heat a bit more manageable.
