> If a person needs 5L/day for survival (I am making this up), then you’d need to dry out 5000 / 2.6 = 1,923L of air each day You made a unit conversion mistake there. It's 1923 cubic meters, not liters.

Aren't they equivalent?

  liter = 0.001 Cubic meter I was curious so I looked it up because I also did not know, ref: https://www.google.com/search?q=liters+in+cubic+meter&oq=liters+in+cubic+meter https://www.google.com/search?q=liters+in+cubic+meter&oq=lit...

    Or to better visualise it, it is a 10x10x10 centimetre (cm) cube. (Or just a bit less than a 4x4x4 inch cube for the unmetrical )

    Oh my you're right.

Correct. 5,000g / 2.6 g per m^3 = 1,923 m^3 Okay let’s say the bottom 10m of atmosphere is available for water making. That means there are 10 million cubic meters of air per square km, or per 50 people. We will need to dry out 1,923 x 50 = 96,150 cubic meters of air. But there is 10,000,000 available, meaning we are only drying out just under 1% of the air.
