Bangladeshi innovator builds incredible zero-electricity air conditioner using discarded plastic bottles

This Amazing No-Electricity Air Conditioner From Plastic Bottles-3

Few people can do without air conditioners during the summer months. However, in Bangladesh, where temperatures often soar to over 40 degrees Celsius this time of the year, air conditioning is not an option, simply because majority can’t afford it. To overcome this, local innovator Ashis Paul has come up with an incredibly innovative DIY cooling system that requires zero electricity. What is more, it is fashioned out of empty plastic soda bottles, thus reducing pollution.

So far, in only three months, Paul’s company has successfully installed these Eco Coolers in more than 25,000 houses across rural Bangladesh. Described as the world’s first “zero electricity air conditioner”, the contraption is surprisingly easy to build and install. In keeping with the creator’s desire to help as many people as possible, a team from the multinational advertising firm Grey Group put the design online at no costs whatsoever.

This was done so that people living in remote, rural areas across the world can easily construct their own Eco Cooler system. As the developers reveal, a group of volunteers from the Grameen Intel Social Business actually helped installed the system, while also showing the locals how to make these on their own. The design is indeed quite simple, and basically comprises of a board that can be fitted in place of a window. The board contains a series of bottleneck-sized holes, which are then filled with empty plastic bottles whose bottoms have been cut off.

When installed, the wider ends of the bottles are intended to face outward, in order to catch any passing wind. This means that the contraption can channel cool air into the building’s interior, without consuming any power. While its efficacy greatly depends on the prevailing conditions, the Eco Cooler is claimed to reduce indoor temperatures by an impressive 5 degrees Celsius, which is what most centrally-mounted electric air conditioner are capable of doing.

According to the team at Grey Group, the system can lower inside temperatures from a stifling 86 degrees Fahrenheit (or 30 degrees Celsius) to a comfy 77 degrees Fahrenheit (approx. 25 degrees Celsius). In Bangladesh specifically, the Eco Cooler technology could prove indispensable, given that over 70-percent of its population resides in tin-roofed huts that are found to heat up quite quickly.
