um... at certain temperatures, water doesn't flow at all anymore, 
it turns to ice
;-)
(couldn't resist pointing that out)


Another druther about doing something with plumbing, with respect to the
teenagers rummaging about, is the price of copper.
Here in my part of the US, it's up to $2.00/lb (usually it's around
$0.50/lb or so).  Anything made of copper that's not securely affixed or
under security has become a potential target of copper thieves lately.
You'd have to also remember not give the teenagers some free copper with
your plumbing as well if you go with a hydraulic idea.

So... you're looking for a way to create a drive, that doesn't need
electricity (not available), batteries (heavy to lug about), can't use
solar panels (will get stolen), etc...

How 'bout a wind-up mechanical device - something like a larger,
longer-running version of an egg-timer?  Just a random idea for thought.
