Yet another promising example of how Bangladesh is transforming itself into a powerhouse of innovations, inventions and has the potential to turn into another major superpower. Are you a part of the rural midst of Bangladesh where inhabitants are living in tin huts and deprived of any electricity? And also where, the thermometers display a spike, up to as high as 45 degrees during summer and surviving the heat becomes a real headache, literally? The inhabitants become the prime victims of the scorching heat, productivity of individuals seem to fall a lot, dehydration tends to become more common, infants suffer a lot and heat stroke becomes a much common phenomena? Or, are you in a much formidable position but still pull your hairs everyday for noticing that the power bills have spiked up or are concerned about your bills rising if you purchase an air-conditioner?
In the developing Bangladesh where waste management hasn’t reached to much efficient standards, there is a huge amount of wastage, specially coming from plastic, around 50 billion water bottles are used up annually and only 20% get recycled. Tech visionary Ashis Paul has given a lot of thought about how to deal with the matter and figured out how to repurpose these non-salvaged plastic bottles into low-cost, easy-to-make, electricity-free Eco-coolers. Plastic bottles cut in half are installed on the board, The board is then placed over a window with the narrow bottleneck facing inward. The technology behind the Eco-Cooler is based on the idea that the bottleneck becomes a funnel that compresses and cools the air that runs through it by about five degrees, It follows the theory about blowing air through pursed lips, the air that comes out is cooler despite the body’s natural temperature.
The Eco-cooler initiative has shown promising results where, these natural electricity free air conditioners have been installed to over 25000 households by Grameen Intel and employees and Grey Dhaka volunteers and have had created massive positive impact on the rural inhabitants, who knows, the same initiative may go global and be introduced to other lowly developed or developing countries have power shortages.
