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.

sorry but isn't that just a good dehumidifier? Is there something new?

And how much power does it use?

This thing works self-contained and off grid - using materials that have huge surfaces to condense the water. It is mentioned that there are powered versions too, but the principle itself does not need extra power, the Sun drives the condensation.

That's still embodied energy, so the question becomes; "How much energy does it take to actually make these materials?"

In particular, the device is packed with Metal-Organic Frameworks (MOFs), which are synthetic porous materials engineered at the molecular level to have huge surface areas. A few grams of an MOF can have a surface area equivalent to a football arena, according to the source.

That sounds pretty energy-intensive to me.
