I know that many eggheads are also homebrewers. Homebrewers trend to have access to a CO2 tank. So, I'm surprised I haven't heard about anyone trying to close the bottom vent, open the top vent, and fill the egg with CO2 to extinguish the coals. This should be much faster than waiting for the coals to burn themselves out.
Is this sound?
Has anyone tried or heard of this?
