Vapor-collection technology saves water while clearing the air

&gt; ...vapor collection could be made much more efficient by first zapping the tiny droplets of water with a beam of electrically charged particles, or ions, to give each droplet a slight electric charge. Then, the stream of droplets passes through a wire mesh, like a window screen, that has an opposite electrical charge. This causes the droplets to be strongly attracted to the mesh<p>Woah, this seems really simple and possibly applicable to other situations where you&#x27;re trying to condense a vapor.

I guess at some point we&#x27;re going to have to use a programming language to interface with these things.<p>Will it be something like the ones used for binary load lifters?

I wonder if this tech could be applied to evaporative cooling systems for data centers in hot regions to capture the water that is otherwise lost.<p>I know many of the big data centers use a ton of water in areas that don’t exactly have water to spare.

If you find this interesting, there are other technologies either proposed or used to collect atmospheric water.<p>Air wells: <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Air_well_%28condenser%29" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Air_well_%28condenser%29</a><p>Fog collection: <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Air_well_%28condenser%29" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Air_well_%28condenser%29</a>

This seems like a roundabout way to achieve a closed-loop cooling cycle. Why do this vs a water-to-air heat exchanger and never evaporate the water in the first place?

If this became widespread wouldn’t this negate some of the positive side-effects of creating more light reflection on earth? <a href="https:&#x2F;&#x2F;www.bbc.com&#x2F;future&#x2F;article&#x2F;20190220-how-artificially-brightened-clouds-could-stop-climate-change" rel="nofollow">https:&#x2F;&#x2F;www.bbc.com&#x2F;future&#x2F;article&#x2F;20190220-how-artificially...</a>

This is ultimately almost useless because the minerals in the water are more important than the water itself.
