Claim 19:
20. A device, comprising:
a first electronically conductive porous solid;
a second electronically conductive porous solid electronically coupled to the first electronically conductive porous solid; and
a medium between the first electronically conductive porous solid and the second electronically conductive porous solid;
wherein the device is configured such that:
when an electrical potential is applied to the first and second electronically conductive porous solids with a first polarity, a fluid permeability of the first electronically conductive porous solid is reduced, and
when an electrical potential is applied to the first and second electronically conductive porous solids with a second polarity opposite the first polarity, the fluid permeability of the second electronically conductive porous solid is reduced.
