Who are those CGA guys? Compressed Gas of America or what?
And how did they came up that 8 hour (1 night?) stand/1 hour
tumble standard?
How about having a bent valve stem inside the tank, so the inrush of
gas when it gets filled setup a good swirl inside (if ever the
"terminal" velocity of the gas as it enters the tank is high
enough), if *EVER* some kind of "mixup" is needed?

The fact that the Communists won the elections in Russia show how the *PEOPLE*
think about the "system" the rabid entrepreneurs have been shoving down their
throat. It also shows that when you run around with a MBA in one pocket and
an adding machine in the hand (an MBA brain obviously can't handle anything
more complex than addition), you have tremenduous farsight. At least, the
bureaucrats don't make false promises and spew bullshit all over.
