Hello,
I'm looking for some advice please.
I need to check on the average wind speed over say 6months on a piece of
land I intend building on, with a view to maybe installing a wind turbine
for electricity.
I have searched the web for hours, but cannot find many that work remotely.
I need to fix it onto a post and will have no mains power available. There
is a suitable one which works via a small bicycle odometer display...but
out of stock.
Any advice would be appreciated,
Thanks,
Steve.
Pls reply to NG.

It would be a wise man who did a google and read about the drawbacks of
that database.

Maybe, however the site admits to limitations. Anyway it was only a
suggestion.

Yes thank you Tim, I have already looked there, which gave me a 'ball-park'
figure. However due to the unique topography of the site, I would like to
get specific data before investing the best part of £20K in a turbine setup.
Thanks again,
Steve.

Fair point. You don't want to blow £20K on a fan in the wrong location.
Hope it works when you get it all installed.

Suggestion: why don't you buy a cup-counter anemometer? These are
purely mechanical instruments (need no power), and indicate the 'run
of wind' in the same way as a car odometer. You could then work out
the average wind speed over any period between readings - an hour
apart or a month apart - by simply noting the anemometer display and
subtracting the previous reading from it, then dividing by the number
of hours between readings.

They have rather gone out of fashion these days. There was one going
on e-bay a few days ago for £200; I'm sure Casella's will still sell
you one. A sturdy mast to expose it at the height of your planned
turbine - job done. You'd probably even find a willing buyer on e-bay
for a 6 month old anemometer afterwards.

Thanks for that Stephen.
Yes I saw the cup/mechanical one, and missed out on it by literally a few
minutes. Apparantely they cost over £85o new, but as you say would have been
ideal.
Really my question is where can I get something similar?

Well you'll get the mean speed but I suspect that knowing the peaks might
not be a bad idea so you can tell the turbine people the real conditions
it's going to have to survive. I wouldn't be surprised to find the
longish term mean speed here to be between 10 and 15mph but that doesn't
stop periods of sustained speeds up to 50mph with gusts 20mph higher...

The winds round here have killed two small turbines in less than a year
to my knowledge.
