Abstract: Devices and methods for atmospheric water harvesting may be useful to obtain drinking water from air of moderate humidity, in a process driven directly by solar energy. Devices feature a recirculating stream of a fluid, such as air, and include heat recuperation to heat fluid in one portion of the stream using heat contained in another portion of the stream. Passive heat sinking is sufficient to condense liquid water, without need for refrigeration. The objective of the technologies and inventions is to enable affordable household products that improve drinking water access, with a focus on those currently without access to safely managed drinking water.
