Hi again guys
Well, it's been a crazy few weeks of researching deep ocean submersibles and CO2 poisoning for the first 3/4 of the story, and I'm now circling back to the free ascent final stage.
I do have a couple of quick questions:
1. With a makeshift dry suit, is it necessary to constantly release and seal in place of an Overpressure Valve on ascent, or could I have plastic tubing going from the inside of the suit to outside at key places (neck, wrists etc.) to continually release pressure on the ascent?
2. Would either of the vessel flooding scenarios in my post above be possible/suitable/plausible?
3. The only, and ironically, compressed gas that the vessel has available is a CO2 fire extinguisher for electrical fires. Will this fill and lift an open bottom blow bag?
I don't want to go too Hollywood and have them try to use the extinguisher for ascent, but filling the bag with CO2 outside the vessel is likely to be easier than filling it with trapped air inside, then trying to drag it out after the flooding.
Thanks again for your help!
