I used to advocate CO (carbon monoxide), its easy enough to manufacture on site. But Nitrogen will do as well!

Dude, that's a loser because it contains .....

carbon!

Lord knows, we can't be spewing carbon out into the atmosphere or anything. CO is even worse than CO2 from what I hear from Chicken Little and his cohorts.

Of course, the whackjobs might be able to claim that since nitrates are used in explosives, and that nitrates contain Nitrogen, that's it's a non-starter as well.

I say we kill the whackjobs first.
