Great find indeed! The idea is not new, or anything close to efficiency, especially for places lacking water in general (80-90% humidity air?), but the portability is great, as well as the possibility of effortless water desalination/purification potential on the go (the Sun has already done half of the work necessary for that). I will definitely going to try rigging the peltier I have for improvisations that way and see how efficient could it be, lets say, while driving along the ocean.
