Device that can extract 1,000 liters of clean water a day from desert air revealed by 2025 Nobel Prize winner (www.tomshardware.com)

The system can function in air with 20% humidity or less. But these 1,000 liter a day machines are not small, at around shipping container size.

Not that I think your device has the same danger because water captured from the air will likely quickly be released again into the same air, but I think this is not a very good example of the safety of your device:

It’s similar thing to taking water from a river. If we take all the water from a river, can we dry up downstream? Yes!

We can and we do. The Colorado and the Yellow river no longer consistently reach the ocean.

The comparison I was trying to make is that we do have the power to capture 100% of a river. This isn't good, for obvious reasons. Humidity capture is a much different process, since we can't just capture 100% of the humidity from a panel either. You could have 80% humidity going in, but actually still 50% relative humidity going out. And that would be maximum absorbtion performance!
