Cool result. Although it looks like the mesh they used isn't disclosed everything else seems low tech, which would be good for mass production. Is there any issue with removing nitrogen from the air like this. Does it only work until a minimum nitrogen contents?

"Water (H2O) microdroplets are sprayed onto a magnetic iron oxide (Fe3O4) and Nafion-coated graphite mesh using compressed N2 or air as the nebulizing gas."[1]

Nafion[2] looks really interesting, too.

There is more nitrogen in the atmosphere than water in the oceans.

Running out of atmospheric nitrogen is not a concern.

I was more interested if the supply of nitrogen in a local area would be effected. could you do it constantly in a shed or would you need some vents to pump fresh air in?

I completely missed that it was a graphite mesh. Not sure how difficult that would be to manufacture but it's at least an abundant material
