A single pneumatic cylinder will break a 16-beam in half fairly readily.
My (big) truck crane boom weighed about 4lbs, mith a center of mass about 18"
from the bottom, and 3 cylinders could lift that when perched about 5" from the
pivot.
So, yeah, pneumatics are powerful enough for most things. The problems are 1:
you need a compressor to power them, which eats batteries; and 2: you need a
(micro)motor and pneumatic switch for each output channel as well as the
pneumatic cylinder. Fredrik will not be doing this in his small, elegant
models (I think... this is not a challenge, boyo :)
Compressors are easy - but my one uses two older 9V motors, 4 compressor pumps,
two storage cylinders, and is about 16x12 square and maybe 12 bricks high. Not
small. And it still only powers about one extension every second or so. All
that power has to come from somewhere, and pneumatics are lossy which doesn't
help.
