Re: [PSUBS-MAILIST] CO2 Scrubber

Hi,
I dont understand why you dont want to use the sofnolime specially designed
for life support systems, do you want to make your own just to save $50 and
risk your life.
Amazing to see that every year divers die with market rebreathers, yet guys
outhere are ready to dive in carboard sub and milk cartons rebreathers and
try anything for the freedom of doing it.
A "regular" sub is ALREADY difficult and tricky to put together, why even
considere nuclear homemade sub, flying subs, propane subs, peroxyde subs,
and other out of your mind submersible, did anyone tried telekinesis sub,
warp sub,  or time travel sub, is there anyone left here who wants to build
just a realistic sub?
