WaterSeer توليد الماء النقى النظيف من الهواء الصحراوى !!!

The idea was developed by Nancy Curtis and Don Zacherl in the United States and a prototype was tested at UC Berkeley Gill Tract Community Farm in April 2016.

“Results were excellent; three of the four models tested exceeded water production goals,” the company says. “We have run calculations based on the field test data that show that WaterSeer will generate as much as 11 gallons of pure water a day under the Semi-arid conditions in the San Francisco Bay area.”

Similar to any reservoir, the water collected should be pumped up to help the process continue. The device has  a filter to keep debris and insects from falling into the water.

 water from air. After some investigation, I have found two very interesting models we could build. DIY Dehumidifier and Filter Combo

So the two pipes in that device act as a rudimentary recuperator. The outgoing air is cooling down the incoming air. If the inner pipe was ribbed or corrugated the efficiency would improve even more. 

Heat exchangers require continuous flow.

The water seer inner pipe is only used to extract water so it does not flow, unless when you extract water. The residual air does not flow either.

The outer section is the ground and again does not flow, this issue was brought up in Thunderfoots video in the first place. It still exchanges heat but is limit by radiating heat from the surface or surrounds.

Finally there are 2 types of simple heat exchangers:

• Series which eventually as the area increases the exchange efficiency decreases. This is what is potentially happening here but as ther is no continual flow or either water or ground.
• Parallel - The better of the 2 provide heat differential that improves with increased area. Again fluid flow is required.

This is my limit of understanding based on quick research. Now it is time to calculate with all the facts present. There maybe something I missed but I think it is fairly correct with potential limitation and time available
