this is really interesting, i live in the bay area, are there any consumer product for this, or is it typically only economically feasible at scale?
I'm personally looking into making something that can continually top up something like a 500 gallon water tank every night (when humidity is high) on a residential property. These tanks are prevalent in the drought-stricken, coastal community I live in. You need about 2200 gallons/person/month, of which only 15 gallons/person/month is used for drinking water. So if you can continually collect water throughout the month and have the space for a tank (about the size of a truck bed) then it should be possible to supply most of your water usage off the grid and in a way that isn't draining reservoirs.
