Nice to see That I'm not the only one interested in the weird and wonderful world of wind turbines.
Links to websites,

These sites have some great information, but a little word of caution, before you sign up and start asking question after question I suggest you do some research on the sites themselves. Any question you come up with has been answered and some of the people on these websites hate answering questions that they have already answered.
My own Turbine is small compared with what some of these people are building ( scale it to suit yourself).
For more info on my turbine I have edited the post to say what each part is made from.

Fries.
