   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?

      There are commercially available systems that do that now, one that seems popular in my area is <a href="https:&#x2F;&#x2F;www.aquaria.world&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.aquaria.world&#x2F; .

      As to your question, would it be a problem if everyone did it -- it depends obviously on your definition of &quot;problem&quot;, but consider that most people doing this have no way to dispose of the water they take from the air except by putting it back in the air. It might increase regional power consumption, and smooth out nightly shifts in atmospheric humidity, but unless there is a new river running to the sea, the average atmospheric humidity will remain the same.

         This is fun, thank you! I wonder why home HVAC units couldn&#x27;t just capture the drain water to accomplish something similar for &quot;free&quot;.

            Condensate is not suitable for drinking and 99.9% of homes don’t have a separate gray water plumbing system or storage tank. Even the evaporator coil in the furnace&#x2F;fan coil unit is going to be dirty, and the condenser coil outside is definitely filthy.
