I was amazed to see this Zero-Electricity air cooling system made entirely with easy to get materials that would normally be thrown away! This is an awesome Upcycle or repurpose project that can cool your home down and make it more comfortable and it’s EASY to do!
Here’s how to Make it:
Step #1: Gather as many used, empty soft drink & water bottles. The bigger the better.
Step #2. Measure the Window that you want to make the eco-cooler for, then cut a piece of cardboard out the size of the window opening.
Step #3. Cut holes in the board the size of the rim of each bottle.
Step #4 Cut each of the bottles in half along the body
Step #5 Cut away the very top of the bottle cap to help keep the bottle on the board without the need for glue or tape.
step #6 Push the cut bottle from the underside of the board, then twist the cap on the (inside) of the board to gently tighten into place. Repeat until all bottles are in place.
The Science Behind it aka why it works
when the air passes through the neck of the bottles, it is compressed, cooling it. as the hot air rushes through it starts expanding, the rapid expansions of the warm air causes it to cool. as an example, hold your hand, palm facing you in front of your face.
open your mouth and blow onto your hand with your mouth wide open. now, purse your lips together and do the same- see the difference in temperature?! cool beans man.
here’s the video, this invention was created by a bangledeshi man named ashis paul who strived to find a way to keep his modest home cool.
