"extracts water from air using cheap, readily available materials... keeps solar cells/ semiconductors cool, repurposed for irrigation, washing, cooling buildings... adding lubricant coating, polymer/ silicon oil, collects more water using gravity... coating eliminates pinning, enabling passive water collection driven by water... passive radiative cooling... vertical double-sided architecture... almost double water collection rate... no mechanical parts like compressors, fans, reducing maintenance"
