Ah, thank you so much! That first Nature article is inspiring—I’ll be twiddling my brain-thumbs tonight. (Sadly, it seems sea water’s salt and particulates might gunk-up their evaporator-engine’s pores; it would be excellent to deploy for the fresh water bodies that accumulate as a result of sea-water evap, regardless!) That article mentions generating a third of a terawatt, and saving a hundred billion tons of water, in the US alone, which would be spectacular—I hope that they can keep capital costs down, when they get devices out of the lab.
Desiccant cooling is sweet—you can also use cold desert nights to make ice in shaded ponds, (Persians were first, I think...) and if that gives you brine for salt, add the salt back to the ice for even lower temperatures! And, atmospheric water harvesting is lovely, especially the small-scale, low-budget stuff for people denied infrastructure and credit. You could definitely add dew-nets deeper in a large desert, to increase the residence-time of any moisture that traveled so far, multiplying the accumulation from yarn-evaporators!
Most of all, thank you for linking Metaphor Search! Your hope has been fulfilled—and I hope you were able to rest well!
a metaphor search from the first couple of paragraphs:
Potential for natural evaporation as a reliable renewable energy resource
Concentrated seawater brines for use in solar-powered desiccant cooling cycles
Global potential for harvesting drinking water from air using solar energy
Desalination at low temperatures and low pressures
hope these links help, idk, I should sleep
