  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.

      Sun: no more free power for you click

      Every living thing as eternal darkness consumes us: AAAAAAAHHHHHHHHHHHH

      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.

  This guy got his Nobel prize for molecular sponges that can bind and release water.
