Great stuff, thanks. I think I've seen that mill before, but not that video, so thanks for posting. Water and wind powered sawmills go back a long way, and still make so much sense!
Would have been interesting if the guy had learned to keep the camera steady. I started getting motion sickness after about 30 seconds! When I worked with film/video, "hosepiping" was the term for that sort of camerawork and it was rightly excoriated.
