  I’d recommend reading the article before trying to make a comparison.

  When water condenses on surfaces, it usually requires either a drop in temperature or very high humidity levels. Conventional water harvesting methods rely on these principles, often requiring energy input to chill surfaces or a dense fog to form to collect water passively from humid environments. But Lee and Patel’s system works differently.

    Isorhermal (unpowered) water condensation from capillary action isn’t the interesting part, (and the article title doesn’t really make that clear), but the potential ease of water extraction after condensation is interesting - and the original paper makes it clear in the discussion that that part isn’t done yet and isn’t guaranteed
