As plastic bottles replaced the air conditioning thousands of Bangladeshis

Outside the window is getting hotter, and residents of megacities include air conditioning on full blast. But on the planet many cities and even countries where the hot and humid all year round, and people can not afford modern luxury.

How to cool down the room without electricity, came up with the project developers under the name Eco-Cooler. To create such a device need ordinary plastic bottle and a piece of cardboard. This uncomplicated design has been installed in more than 25,000 homes in Bangladesh, whose people live in tin huts without electricity.

Make a "conditioning" is simple and not expensive at all: on a piece of cardboard should be cut with a hole diameter of the bottle neck.





then cut off half the bottle and leave some to the neck, and cut off the top of the lid with scissors.





remains to insert the bottle into the board ...





... spin caps with the other side and set design on the box so that the necks looked into the room.





The greater the difference between the diameter and the diameter of the neck of the bottle, the better. Try to get some wide-open mouth on his hand - you will feel the heat. And if you breathe, his lips folded into a tube, the air will become cooler, does not it?

It works the same simple principle: hot air will flow into the bottle, but because of the narrowing in the neck it cools, and the room will be cooler The difference of about 5 degrees Celsius, but in tropical countries even a coolness. already noticeable. This is the case when a brilliant, simple, useful and affordable. This simple "air conditioning" and you can make yourself - take on a note, suddenly come in handy.
