- vrighter 8mo agohow does it avoid the problem that in very dry places there just isn't enough water in the air? Where did they get that 1000 liter figure when all they have is a small lab prototype? this has been invented numerous times and each time it was a gimmick.
- SapporoChris 8mo agoDesert humidity is typically between 10 to 30%. The device is rated as functional at 20%. Extrapolation is commonly used predict values outside of known data. Yes there is a risk of inaccuracy, but it shouldn't be outright dismissed.
- vrighter 8mo agoi am easily dismissing it because this is not the first time someone pitched something like this. It never really works. This extrapolation was wrong in all cases so far. And "as low as 20% humidity" was a feature of most of them too
