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.

Among Grey’s ideas to emerge just before the deadline for the Cannes Lions this year are RainSprout, a widget fitted to the top of umbrellas to help prevent mosquitos from reproducing, in-game ads to encourage Southeast Asia gamers to give blood, and English lessons for Mumbai slum kids delivered by candy sellers with radios.
