Functional Surfaces A4 - Fog Harvesting (Advanced)

In the last part of this section we looked at the Namib Desert Beetle. In this video we go further and study the Cotula Fallax plant species which has a 3-dimensional water capture mechanism. We also look at the issues faced by current fog harvesting nets and the next generation of biomimetic designs.
This is the second part of section 5 in this series of online video primers teaching about the behaviour of water on surfaces. This video is designed for ages 18+ (Undergraduate level).

I wonder if many thousands of these fog catcher devices were to be placed in the high mountain elevation watershed areas of the many lakes that are now drying up ( such as Walker Lake in Hawthorne, Nevada USA and Lake Mead in Nevada ), if then these lake water levels could be gradually brought back up to their normal desired water levels.

Human effort is always too limited .

I saw blue gum trees making rain from moist air in cape town at 3to5 am. No clouds whatsoever

Please use a windmill style post to hold the net for facing the wind

[@st.michaelthearchangel7774]

That's awesome.

[@lm2193]

good and clear

[@meiji728]

can we use routine shadow nets for catching fog ? they are also made of same propylene material ?

[@andthesunsets]

Good presentation. Some rough numbers would help.

[@yolisurich4025]

Have you tried planting those plants in the fog areas to add water to ground. Or maybe they're edible and maybe sheep and goats could graze on them. Or they could help water grass planted next to them.

Is it worth trying in such place like Libya where dew rate might be very low ? and is it implemented in high places like mountains or it can be working even at low level locations!

Where to I get it from? My family lives in California and it's hot no rain. I would know how to get it so I can help them with.

[@alaskanalain]

buy garden mesh and see if you can coat it with "rain x" used on car windshields.

[@modestoca25]

This would be useful in California too but people would probably complain that it's an eyesore

[@haythamsaleh9491]

How much would it cost per m2?

[@ConstructionLaw]

can you just use a window screen from home depot?

[@alaskanalain]

Try to find the stainless steel version

[@thientoantranhay4757]

I want buy it

[@crystalsoftheworld9009]

please make more videos
