The design seems reasonable. It seems like a scaled down version of this MIT one that uses similar principles:

So my vote is for working as expected.

> Over this period, the device worked across a range of humidities, from 21 to 88 percent, and produced between 57 and 161.5 milliliters of drinking water per day. Even in the driest conditions, the device harvested more water than other passive and some actively powered designs.

so its making a shot of water ever couple days, provided its not too dry?

you need to scale way way up, not down

		A shot is ~ 35 ml to 50 ml, so one to three shots a day. :p

Many thanks for your link to the article, it was a very interesting read; fascinating to learn how glycerol interacts with lithium salts...

		The team’s new design significantly limits salt leakage. Within the hydrogel itself, they included an extra ingredient: glycerol, a liquid compound that naturally stabilizes salt, keeping it within the gel rather than letting it crystallize and leak out with the water. The hydrogel itself has a microstructure that lacks nanoscale pores, which further prevents salt from escaping the material. The salt levels in the water they collected were below the standard threshold for safe drinking water, and significantly below the levels produced by many other hydrogel-based designs. So uh, how do they get the salt out of the nanostructure? This design seems amazing but it seems like many of these designs have issues with salts accumulating and clogging up parts thereby requiring some manual maintenance or replacement parts

Both devices handwave on how the cooling required to condense the water occurs.
