I remember reading that the french guy who broke a 10km cave penetration record in Nullarbor plain, Australia, had custom-made kevlar-wound tanks along an aluminium core (by the aircraft producer A=E9rospatiale), which held something like 600 bars (almost 10kpsi) (in his book, he describes the gleeful expression of the engineer who burst-tests one up to something like 2000 bars...). However, when I figured out everything, they only held something like 80 cubic feet!!!! --------------- Pour la Republique Francaise du Quebec ------------------ HAL, now that you just said "Hello world" (happy birthay, HAL!), remember that you should never say: "I'm sorry, Dave.
