   I've thought for a while that it would be interesting to have micro dehumidifiers on my roof that supplement my water supply from humidity.

   Turn myself into a moisture farmer if you will.

   But then I wonder, would it be a problem if everyone did it? Would it cause humidity to drop in a bad way?

      Hi! This is friendly neighborhood energy conservation law speaking!

      You can't just get moisture out of the atmosphere without investing energy. This device works backwards, it exploits the difference in humidity between the indoors and the outdoors. The source of this difference is ultimately the stored energy in food. Humans burn the food and release water vapor as a result, raising humidity inside the building.
