I stumbled upon the following video on Facebook:
I tried to find something regarding heating/cooling of air by compression/decompression, but I came up short. I can easily imagine this working like a fan, creating ventilation. But cooling the air? Furthermore, I would also guess that the degree of actual compression would be quite insignificant. I would quickly call BS, but I might be too early. I would have researched this myself but had a hard time figuring out how to find the relevant physics.
To be honest, this makes very little sense in my head.Most homes in Rural Bangladesh are made out of tin huts that go over 45° celsius during the summer. Our employees volunteered and teamed up with Grey Dhaka to address this issue.
Re-purposing used soft drink and water bottles, The Eco-Cooler works without electricity to reduce temperatures up to 5° celsius.
Grey Dhaka unveils world’s first zero-electricity air cooler made from plastic bottles
Zero electricity air cooler from Grey DhakaGrey has come up with an idea to keep rural housing in Bangladesh cool using re-purposed plastic bottles and no electricity in time for the hot summer months and the advertising awards season.
The agency teamed up with Grameen Intel Social Business, a Dhaka-based social business IT company, to create grids made from plastic bottles cut in half that can be placed in windows. The agency claims the Eco-Cooler can reduce the temperature of a room by five degrees celsius.
The video explains how the Eco-Cooler works with the same cooling effect as a person blowing air with pursed lips.
Eco-Cooler“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”, Syed Gousul Alam Shaon, managing partner and chief creative officer at Grey Dhaka, said in a press release.
The agency claims the Eco-Coolers have been installed in villages in Nilphamari, Daulatdia, Paturia, Modonhati and Khaleya.
Grameeen Intel Social Business’s deputy GM Abdullah Al Mamun commented: “Since most rural homes in Bangladesh are made with corrugated tin, the Eco-Cooler has the power to provide relief to millions of Bangladeshis. We sincerely hope this volunteer effort will make a difference in their lives.”
The Eco-Cooler is another idea from Grey that fits with what the network’s creative head Per Pedersen describes as “solvertising” – work that solves social and environmental problems.
