[ATM] water drive

[Dominic-Luc Webb <dlwebb@canit.se>]

Surely this is not original, but as per my recent posting to
this list, has anyone built a drive that has some extension from
the polar axis floating on water (like sitting on a rubber ball),
kind of like the plunger in a toilet, and just let the water drain
via a regulated valve. I am no engineer (but recently & successfully
fixed my toilet). The motion seems very smooth, although the ball
would presumably have to be pretty large to carry much of a load.
Most scopes are actually pretty small, and there seems to be interest
in lightweight designs (like our earlier carbon fibre threads). I am
curious what problems this would have.
