[PSUBS-MAILIST] co2 scrubber

[River Dolfi via Personal_Submersibles]

I don't see what the aversion to using desiccant is. Silica gel desiccant
are rechargeable, so wouldn't be expensive at all to utilize. After they
are loaded with water and the indicator changes color, you simply bake it
in an oven and it's good as new.
