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.
