Vapor-collection technology saves water while clearing the air

  • > ...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

    Woah, this seems really simple and possibly applicable to other situations where you're trying to condense a vapor.

  • I guess at some point we're going to have to use a programming language to interface with these things.

    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.

    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.

  • 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? https://www.bbc.com/future/article/20190220-how-artificially...

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

  • > About two-fifths of all the water that gets withdrawn from lakes, rivers, and wells in the U.S. is used not for agriculture, drinking, or sanitation, but to cool the power plants that provide electricity from fossil fuels or nuclear power.

    This is fucking stupid. What the fuck are they talking about outside of the environment industrial complex cult HN loves?

    Does anyone know?

    Is it Thermoelectric power? Or is it as usual MIT outright, day in, day out lying?

    Is there any source? I'm not sure what to even check?

    This implies it disappears - "leading to huge white plumes that billow from their cooling towers"

    40 motherfucking % of supply? Or is the lie "lakes, rivers, and wells" is not a dam? Which is still fake. HN sugar for the mice I guess?

    [] The ratio between net consumption and withdrawal is estimatedat less than 5%. It includes water for the cooling of thermoelectric and nuclear power plants, but it does not include hydropower. https://ourworldindata.org/water-use-stress
