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.

    "Energy intensive".

    There are also commercial versions that are designed for permanent use. Again, zero energy use.

    Generally when you make a claim, its on you to back it up with evidence, not everyone else to 'prove you wrong'. "God is real, prove me wrong."

    That works great when there is moisture in the air, whwn there is moisture in the air, there is usually a better way of collecting it for less energy.

    You posted a solar still, a device which uses solar energy to distil water, an excellent solution to get water while on a desert island.

    It won't nearly as well in dry climates

    Also, "zero energy use"?

    Are you high?

    Sunlight is still energy, it absolutely uses energy.

    Finally, the is a new adaption of an old tech that has been proven to not work as advertised time and time again, it is on the creators of the new tech to prove that it works, I don't have to disprove this at all, that has been done time and time again.

    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

    People just want it to be true. They're willing to buy into the scam.

    Yeah, I remember watching Thunderf00t's videos on Fontus and the other stupid shit

    I would not put any stock in anything Thunderfoot claims, he's a grifter and makes profoundly dumb arguments.

    Source is biased obviously, but contains many, many references: https://skepchick.org/2025/01/thunderf00t-is-still-an-ignorant-loser/

    Nah, he was right then and is still right. The anti feminism thing was a weird tangent that a lot of the skeptic channels did go down for a while. Then a lot of them continued down that road and became alt right. Thunderf00t did not.

    Remember that a person can be a dick and still be correct.

    I did find his rant about feminism to be annoying and over the top, but when it comes to science, like it or not, he has plenty of credentials.

    But since you dismiss him so easily, please tell me what he is wrong about with regards to water from air tech.
