Re: [PSUBS-MAILIST] CO2 Scrubber

["Herve" <caribsub@coqui.net>]

An engine hoist does not kill!
A defective CO2 scrubber without the right sofnolime will kill you.
A miscalculated hull will crush you at depth without warning.
You can bet on it. however if you considere sub making as a game that s your
life. Long time ago i learnt while student engineer that engineers dont
play, they may have fun but they dont play. Play and you will go broke,
loner or dead.
I would say that like in aeronautic what makes a good subman is an old
subman.
There are thousands of other items that are left to design and build that
are not "life support" why dont you focus on those, you will go under the
water sooner and safe.
