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.

    In other words, a dehumidifier.

    There’s no such thing as a free lunch. To condense water fro air, you need a lot of energy, considering how little humidity there is in a desert, it would be better to just use that energy to bring the watter from somewhere else rather than running the dehumidifier.

    What pisses me off, is that we’re willing to build thousands of kilometres of pipe to transport dinossaur juice but not watter.

    Fuck this capitalist system.

      A passive water harvester based on MOF-303 has been designed and configured to achieve the highest efficiency among passive designs. A water harvesting capacity of 285 g H2O per kilogram of MOF-303 per day with only ambient sunlight and no power or other energy input was achieved. The MOF cartridge design and the condenser surface treatments were key features in achieving high water harvesting efficiency especially when tested in the field (Death Valley National Park).

      From the paper.

      It’d be really nice if people actually read the article instead of just assuming they already know everything.

      This system does not require a power source.

      Yaghi’s mechanism can do this without a power source. It uses the wind and air for water input, then the sun to drive condensation and evaporative action.

      Water has only one T. One of the many things wrong with your argument. Read the article.
