This has been debunked before. To get 1000liter of water out of the air, the air needs to hold that much water.

This is a bit more serious than the old, frequently-debunked “dehumidifier in the desert” stuff, because it doesn’t depend on cooling the air to get the water out, but using a molecular sponge. If you pump enough air over that, you’ll eventually fill it up, and you can drive the water out by heating it up.
The guy behind this is a serious organic chemist, and his Nobel prize was actually for pioneering and developing these molecules, so it’s not a case of “Nobel prize winner does daft stuff about a subject he’s not an expert in”, either.
I’m still reserving judgement on whether this will be economically sensible, but I’m not dismissing it immediately, either.

By gods. It doesn’t matter what technique you use, it’s still just a dehumidifier! The immediate limitation is the humidity of the air, and deserts aren’t known for being very humid!
