I'd like to add a point in regards to the carbon that the military is using.
In a few of the military articles I came across, a reference was made to the amount of carbon being used. The military uses much more carbon than you would find in a SL suit. I remember a thickness of 1/4" being referenced.
The military uses carbon to keep chemical warefare agents "OUT" and is not trying to adsorb an odor from within. The uses are of an obvious difference. As such, I would think the re-activation process necessary would be dramatically different. Logic would dictate that it takes alot more heat/regeneration processes to work on a 1/4" of carbon than a thin layer that is in SL. That being said, keep in mind that SL is not trying to adsorb a deadly chemical agent..... Unless you ate suicide wings the night before.
