You are correct I did mean "Anemometer" - I'd love to call that
misspelling a typo but I realise I did it twice today *sigh* - I do know
the correct way anyway :)

I was thinking of the windmill/current concept - though am open to better
suggestions.  We're planning on building a small rover to "run" up the
mountain and return environmental information, video, and take a new set
of operating commands.  Essentially a "Mars Rover", just a bit more local
to home :)  We'll be using Amature band packet radio for the
communications, and a small 1 watt video transmitter to view what the
rover does.  One major advantage is we can always walk up and recover the
beast if there is a problem :)  We're a ways off from final success, as
I'm trying to let my son's do the work.

  Interesting you should mention that.  I've been toying with the idea of
making a anenometer (wind speed tester) from a motor, but haven't over
come the idea of how to calibrate it.

I believe the word is anemometer... it's really just a form of pressure
gage.  Were you just thinking of attaching a windmill to the motor to
produce current?

I've seen various ideas postulated on this list for pressure gages (or at
least limiters) for use with the Lego pneumatics system, but nothing has
come down the line that would be sensetive enough to detect the few psi
difference between static and total pressure at any reasonable speed.  On
the tunnels here at Purdue, for the lab courses we have big sensetive
pressure gages, and on the big Boeing tunnel we have more sophisticates
and expensive things like seven-hole pitots and multidirectional hotwires
and...
