tl;dr (copied from the abstract): “Here, a generic effect for continuous energy harvesting from air humidity is reported, […]. The common feature of these materials is that they are engineered with appropriate nanopores to allow air water to pass through and undergo dynamic adsorption–desorption exchange at the porous interface, resulting in surface charging.” “The work opens a wide door for the broad exploration of sustainable electricity from air.”

They call the effect an ‘air-gen effect’ so more articles can be seen here: https://duckduckgo.com/?t=lm&q=Air-gen+effect&ia=news
Well… the question should be: where does all this electric charge come from? I you harvest it from humidity in the Air, the charge would removed. Thus, you have to replace the humidity in the air with fresh, „charged“ humidity.
Is there any natural effect, that this works automatically? Or do you need a fan? How much energy would that need?
Too much questions, too less details for a too simple solution.
