Summer is upon us, and complaints about the heat will soon be common in many places. Most homes in Rural Bangladesh are made out of tin huts that go over 45° celsius during the summer. Ashis Paul developed a clever DIY cooling system that doesn’t need any electricity and is built from a common waste item: empty plastic soda bottles. In just three months, Paul’s company has helped install its smart powerless air conditioners, called Eco Coolers, in 25,000 households.
Inventor Ashis Paul has been a breath of fresh air, in more ways than one. He came up with a brilliant and easy way to draw cool air into a house using plastic bottles, and his company has been installing them in developing areas across the country.
The Eco-Cooler, can change the temperature by 5°C almost instantaneously! When speaking with The Observer, Jaiyyanul Huq, creative director with the Grey Group, the advertising company that spearheaded this social project said, “We are a flood-prone nation, so in rural Bangladesh, most people build their homes out of tin, instead of mud. About 70% of Bangladesh’s population lives in these homes.
But the problem with these tin huts is that they get unbearably hot in the summer, especially in northern and central Bangladesh. I’ve been in these huts. It’s like being in a sauna in the Sahara. Ashis has an inventor mentality and he’s always been fascinated by science. So, he started experimenting. He told us about his idea of making an air-conditioner out of plastic bottles. The simplicity of the Eco-Cooler is incredible.”
