At one time there were two towers here. An older and much smaller one was
next to the big one that was just brought down. The smaller tower was also
a variable volume design that worked, at least in principle, much like you
describe; the height of the entire structure changed with stored gas
volume. Don't know if it was the same in design detail as the ones you've
seen. It was torn down long before I moved here and I haven't seen any
photographs of it. Was told they simply disassembled it, since it was
comparatively small and everything was already collapsed almost to ground
level when it was emptied.

We used to have variable volume gas towers here of a different design. The
tower was just an open steel framework, like permanent scaffolding. The
part that held the gas was like a giant inverted cup. I assume the inside
was smooth and the seal was inside at ground level. Also, the structure
itself likely provided the compression weight. You could see how full they
were by their height. Gone many years ago without any explosive fuss.
