A Zeer Pot is an ancient device used to cool things. It was invented by the Egyptians about 2500 years before Christ was born. It works on the principle of evaporative cooling. It's still in use today in North Africa and I'm going to tell you about it and show you how to make and use one. Interesting notes: More wind speed can improve cooling efficiency. Hotter air flowing over the pot might improve the efficiency. Airflow coming off a hot parking lot might improve efficiency if your pot is in the shade because hotter air can hold more moisture which means that it can increase evaporation of the pot's moisture.
Zero Energy Cool Chamber, a low cost solution for storing vegetables and fruits in rural areas.
hi guyz in this video u will be learning about eco coolers and a small explanation about it . its really easy to make u can make it in six steps. the principle is also way to easy to understand.its same common theory but i have said abt joule thomson effect .i said it because they both reassemble the same so i said its main principle is joule thomson effect.hope u guyz like the video . plz LIKE , SHARE and SUBSCRIBE. watch our other video: 1) How To Make a Mini Simple Audio Amplifier https://youtu.be/6cAtm7ER1jQ 2) Mobile phone life hacks https://youtu.be/msvW6_Apa68 3) How to make an inverter at home https://youtu.be/qqFHNy5helQ 4) 5 Simple Life Hacks https://youtu.be/ym0WcQtXdDo 5) How to build a simple aquarium filter https://youtu.be/EaHWco2ryOw 6) How to make a mini pyrography tool https://youtu.be/lTMx-z22gNs 7) DIY Multi Purpose emergency light https://youtu.be/4L-cshWpaC4 8) How To Upgrade RC Car https://youtu.be/ut1ETuDj3Uw 9) HOW TO: DIY aquarium filter https://youtu.be/6y_6Kcuzuks 10) HOW TO: DIY aquarium filter https://youtu.be/mWU3Z8UxBCE MUSIC : http://www.bensound.com for more videos visit our channel u guyz can get many different circuits and crazy projects from Crazy mechanics in facebook Page : https://www.facebook.com/CrazyMechani...
