10-25 gallons a day? If there was that much water in the air in your basement, it'd have its own atmosphere. I have one in my basement and it usually gets no more than a cup per week. And yeah, there's a lot of water in the Earth's atmosphere, but humanity is nowhere near the point of being able to build a dehumidifier capable of condensating at such a gargantuan scale. Even if you were to build one the size of the Burj Kalifa it'd only produce enough water for a small village, and only on a humid day. It's not an issue of supply. It's an issue of scale.
