Using condensation to gather drinking water in Ethiopia

OT scientists, if there were thousands of these scattered over Ethiopia acting as a massive dehumidifier, would it change the climate?

Isn't this what Uncle Owen and Aunt Larue did?

Interesting...

I'm trying to understand, what is going to make water condense out of the atmosphere? Condensation usually forms on a surface colder than atmospheric temperature (like on a cold beverage).

I think it's just a high surface area structure that is collecting natural dew formation from the day/night cycle.

Q: How does every Ethiopian joke start?
A: By looking over your shoulder.

The real question is, would it change the Ethiopians? The answer is no, it wouldn't. While society in general has advanced beyond a primitive lifestyle, equatorial Africa as a whole lags far behind the rest of the world.
There's something culturally which prevents them from advancing, no matter now much money and resources is thrown at the problem.

Resources are finite. To answer the question of whether these structures would change the ecosystem, ask the question "Would having these structures scattered over Ethiopia lower ambient water vapor in the atmosphere to the point that there is a shortage of water vapor at another point where it is needed?"
You could get away with structures like that in places with high humidity and probably not change the ecosystem, but in an arid or semi-arid environment you may be creating artificial shortages that effect something in that ecosystem.

Are you fricking serious with this?

I've wondered this about windmills.

They use up a lot of wind energy... where there are big wind farms they have seen a significant reduction in dust devils and tornadoes. Eventually they might even be able to stop hurricanes.

Definitely not using reverse osmosis, you need a cooled condenser for that. Probably simply catching nightly condensed air on surface area and funneling to bottom. 25 gallons a day seems like baloney to me though.

serious question...wouldn't one of these need to be in an area with relatively high humidity to work and not in, let's say, a desert?
Posted on 4/3/14 at 1:56 pm to JermStone
There's humidity in the night air in coastal desert areas, which can travel inland quite a bit.

The most humid cities on earth are generally located closer to the equator.

It occurred to me that there wouldn't be world hunger if you people LIVED WHERE THE FOOD IS
