> 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
