This video is showing that 3.5m/s to 5m/s wind speed can turn your meter backwards!!! So its feeding back to the grid so my local neighbours can use it too. I can't imagine how much faster the meter will spin at 9 or 10m/s

This was the prototype tower and its' first attempt. Successful. Raised an 800 lb. 10kw turbine. Later lowered, blades attached and raised. Turbine started immediately.
20 kW turbine spinning, notice slow spin, low wind start up, low speed operation
