Hi!

Im not a diver myself, but I have a question someone might have an answare
for.  If you have a bottle with much higher pressure then the normal 200 bar,
what is the cons and pros? Lets say 500-1000 bar.

What about such things as smaller size or less weight? Can there be places
where a small bottle with extremly high pressure can be useful, for example a
bottle with 1000 bar and less than 1dm^3?

In some areas as wreck diving it is perhaps possible to dive with less lead.
A possible problem is non-ideal gasses, but I have no knowledge of how the
actual formulas goes.

The first person entering a shop with such a bottle will at least have some
problems..

John
