How Green Is My Valley(Hill)

As you know we are investigating the possibility of a installing a wind turbine sometime in the future. As well as the necessary funding and planning approval, what is need most is of course wind! So we have made a small investment in a Power Predictor. The anemometer measures the speed and direction of the wind and stores the data in an SD card, which is later used to upload to a dedicated website that gives us the results.

To get the best results the Predictor should be in more or less the same position that the turbine might be - so for us that means by the hedge at the top of "Field at back o' barn" - and as high as possible.

So we started by building a 15 metre pole
We took it up the field and attached the stays that would hold it in place
Laid it out ready for lifting

This is the bit that creates the data

And this bit records it

Ready to raise up

In position and gathering data (we hope)

The longer we leave it, the more accurate the results will be. The controls are lower down the pole and in about a month we'll check the SD card to see that it's actually working, then leave it for at least 6 months.
