Let's start with another question: [[Atmospheric_Conversion_Center|Atmospheric Conversion Centers]] clean air for cities, but what would keep the clean air inside and the toxins outside the cities?

[http://phys.org/news/2012-01-graphene-supermaterial-superpermeable.html Graphene oxide] is known to be impermeable to everything except water (and maybe hydrogen). Graphene has so tight of a structure that almost nothing fits between its atoms. It's also pretty transparent, which would let sunlight still reach the interior of our hypothetical shield.

Other graphene layers attached to the first one could align the material along a magnetic field. Pure graphene isn't magnetic, but doping and defects can change the properties of graphene in many ways.
