The system can function in air with 20% humidity or less. But these 1,000 liter a day machines are not small, at around shipping container size.

If you plan on drinking the water, or cooking with the water, it's going right back into the air after you pee or sweat and the water evaporates. Literally no damage done.

You cannot make the water actually disappear unless you use it in some kind of chemical reaction, and even then it may end up returning to water eventually.

I would think that ripping 1000L of water out of an environment in a day is going to have more immediate impacts than you eventually pissing on a cactus is going to fix…

Sure, the water isn’t “destroyed”, but it is being removed from an ecosystem that has evolved to use every last bit of water it can find to survive. It may not be immediately obvious, but it sounds just as damaging as removing 1000L of water a day from a lake and thinking the ecosystem will be fine because you’re going to sweat next to the dry lakebed.

Well... It all depends on what you do with the water. Are you sequestering it in some way or are you releasing it? I mean, if the community drank 1000 liters of water, then their next piss is 100% going to fix it. Even watering crops is just releasing the water.

Again, if you're going to sweat 1000 liters, then go for it, I fully endorse this plan. Use as much water as you want, it's fine unless you're shipping it out.
