Device that can extract 1,000 liters of clean water a day from desert air revealed by 2025 Nobel Prize winner — claimed to work in desert air with 20% humidity or lower, delivering off-grid ‘personalized water’

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.

    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.
