engineering course, we were using it to compress Martian atmosphere to

it up and it releases the absorbed gas during the day. Same principle makes
a scrubber that can be regenerated and produces no caustic or irritating
dustm as might occur in hydroxide-based chemical absorbants.

We use silver zeolite cartridges for air sampling around the nuclear plant, 
which is the only way I'd have ever recognized the word. Is this unit 
buildable in the real world, John? As in, how cost effective would such a 
thing be when compared to the 20 bucks per dive or whatever for soda sorb 
charges?
