How To Build Your Own Air Conditioner Using Just Plastic Bottles
You might want to think twice before recycling your 2 liter. There is now a way to create "zero electricity air conditioning unit", yes... No power!!!!
Bangledeshi inventor Ashis Paul came up with the plastic bottle air conditioner, and it is already being used in over 25,000 homes in his country!!! Really, all you need to make your own Eco-Cooler is a board and a few plastic bottles.
Cut the bottles in half. Then mount them into a grid through holes which are also bottleneck size. Now place the grid right over the window. The narrower top end should be facing inwards to the house.
Wind will blow through the bottles, and the result is cool air being funneled in. It can reduce temperatures to up to 41ºF (or 5°C) and it doesn’t cost anything to actually make!
