This is why I built an axial flux. Start up speed is under 1 mph, cut in speed is ~3 mph. Consistent production in low wind environments. There's no comparison. It doesn't get any better than this unless we go bigger. I love it!
Here's another (low quality) clip from the DVR showing how well it performs in clean wind. The wind blew from the east for a bit yesterday, which is the least obstructed side of my property, so there was little to no turbulence from the trees affecting the turbine. This will be the norm once the tower is extended to raise the turbine above the trees, where it belongs. Based on the coefficient of a typical radial flux turbine, this turbine should produce AT LEAST 600 kWh per month (in areas like mine with a mean annual wind speed of 5 mps, refer to the Canadian Wind Atlas map turbine performance calculator that claims up to 750 kWh per month). The avg Canadian household uses around 900 kWh per month, to put that in perspective. But radial flux turbines usually don't cut in until 6-8 mph, when this turbine is already producing a couple hundred watts. As some of you know, this is because of the cogging resistance that's inherent in their steel stator core design. This turbine doesn't have that problem. Once the battery bank is upgraded and the clipper is connected, then I'll turn the brakes off for good and start logging kWh production.
