Harvesting water from air the most pointless thing to put money into. The only places with enough water in the air to make it worth it already have plenty of water. This is always snake oil.
Yes, this is 100% accurate!
To the downvoters, please don't just downvote, give me a plausible scenario of when harvesting water from air is more useful than just cleaning existing water.
Condensating water is VERY energy intensive, filtering far less so.
It’s not the condensing that takes energy, it’s the thermal release of the water from the desiccant that takes energy. Here’s the real paper with all the details. Avoiding thermal release in favor of mechanical release of water from the desiccant bypasses a good portion of the energy required.
Cool, but the fact remains that you can't get a useful amount to water from dry air, and in a humid climate there are other sources of water that is cheaper and easier to exploit.
EDIT: downvoting facts I see, please don't turn Lemmy into Reddit
