    i remember these kinda discussions from a few years ago, when waterseer had a similar idea.

    how well these devices work is strongly related to how humid the air is.

    and the places where these kind of devices would actually be useful (like deserts) have very low humidity,

    to the point were there is almost no water in the air to be harvested.

    atmospheric water harvesting has only been somewhat feasible in environments that usually have better methods to get water,
    and even there they are ineficcient to the point where people consider it a scam

      Did you read the article or watch the video?

      Of course deserts have low humidity, but there are areas where in the early morning winds from off shore bring in humid air for a small period of the day. This can be harvested now with nets, although the article and video cover using electrified mesh to increase the yield.

      If you look up for harvesting the first photo in the link is from a desert in Chile. It’s been studied since the late 60’s.
