2000W? Is it industrial strength? You'd probably get a lot more water if you put the dehumidifier outside, though.

I also found this:

That's about 19 liters per day inside an already dehumidified home. That comes out to about 315 watts per liter in a relatively low (30-50%) humidity environment. That's not too bad.

I should get a dehumidifier in case of zombie apocalypse.

I did the legwork for a phd project that involved comparing indoor dehumidifiers efficacy on AWC in a desert. The cost varied wildly, in the 10c-4$/liter range, but that also included tests at 5% humidity and 120F outside, and others while it was raining.

Most places could use active systems like this for cheaper and cleaner water than they're currently getting. I will mention though, the refrigeration based dehumidifier collected every damn particulate in the air with it. It definitely needed filtration. Even moreso, this water is salt-free, and you can't live off that. These are costs to consider when using AWC.
