Scrubber technology itself is really pretty good. The scrubber technology we have available now is pretty cost effective and efficient. Technology already exists to make it easier, more foolproof, and to prevent caustic cocktails (membranes, cartridge systems, traps). Evolutionary changes can certainly be made in these areas, but I doubt they'll solve any real, substantial problems. -p
I deleted your (many) good points, but challenge the above: Chemical scrubbing is the huge achilles heel of current rebreathers. Cryo-scrubbing is the next step... infinite duration, zero consumables save for the cryo (which would also be the gas source), zero caustic coctails, etc. Think out of the box, man!
Rebreathers will eventually go two divergent ways: One to the common-man, who can use the black-box without knowing or caring what goes on inside, and technical 'super rebreathers' using cryogenics, non-chemical scrubbers, near infinite durations, etc. The present state of the art is but a flash in the pan, my friends.
