I saw a comment somewhere that I believe was attributed to Casey saying they'd reached the limits (or were approaching the limits) of what they could do with SCR.
Seeing as how they are talking about CCR's at the GUE conference, I would expect them to be evaluating if CCR will allow them to push further than SCR. This would be a different evaluation from 'are CCR's safe now'.
But that's all hearsay and speculation
It is refreshing that the panel isn't stacked 'against', and the 'dogma' aspect has been set aside. Perhaps this will result in a real discussion. The weeki wachee team proved it could work.
As I understand current Rebreather-80 practices.... Backgas (2 x 130's) is immediate bailout, drive gas is slung (AL80's). Additional bailout and drive bottles are deployed by setup teams along the mission route...
So, what would the move from SCR -> eCCR mean....?
- Reduction of team setup work? Maybe, not significantly, adaquate bailout supplies are still a concern. Maybe reduction of some additional drive bottles, and the bailout considered a longer term stash over multiple missions if left untouched. (Fairly certain they do this today).
- Better Deco? Probably, the extent would really need to be run.
I always wondered why they didn't use some sort of rebreather tech for the O2 deco in the habitat... For as many hours, they've gotta be burning through a few O2 bottles. Even if it's a DAN setup there would be some value here.
