These People Are Using Plastic Water Bottles To Cool Their Homes
Chances are that if you’re reading this, you’re one of the lucky individuals on this planet who has access to electricity and can harness tools, such as Air Conditioning (AC), to stay cool during hot, summer months.
Not everyone is so fortunate, however, which is why an inventor named Ashis Paul developed an ingenious solution to help those in rural, poverty-stricken locations – specifically residents in Bangladesh – cool off.
In three months, Paul’s company developed Eco Coolers, smart powerless air conditioners which don’t require any electricity. Already, 25,000 households around the world are outfitted with an Eco Cooler system, and that number is expected to grow. Many of the systems are behind utilized by Bangladeshi people.
The simple invention is reportedly the world’s first-ever ‘zero electricity’ air conditioner.
How does it work? It’s actually fairly simple. First, a board is cut to fit the desired window. Then, bottleneck-sized holes are cut out in a grid pattern. Next, the bottoms of empty plastic water bottles are cut off and discarded, leaving funnel-snapped bottlenecks that are placed on the grid. All one needs to do then is install it in place of the regular window, reports Inhabitat.
The Eco Cooler works because the wide parts of the plastic water bottles, which face outward, catch the passing wind and literally funnel cool air into the building’s interior.
Paul didn’t develop the Eco Cooler to make a profit. In fact, his top priority was to get the concept out there to as many people as possible. Thanks to the Grey Group, which used its position as a multinational advertising firm to put the plans online – free of charge, exactly that happened.
Anyone can build their own Eco Cooler system, and volunteers from Grameen Intel Social Business are even helping to build and install the units. They’re also educating locals on how to construct the electricity-free coolers, so they might help their neighbors.
