Think huge.  First problem, getting the whole thing ABOVE the trees.  Second, getting the blades big enough and well supported enough that they will turn the motor under load (do all tests with an incandescent light bulb attached to the motor circuit-you wouldn't think it, but there is a HUGE, MASSIVE, ENORMOUS difference between a generator free spinning and one producing power).
