Winds were 10-14 mph today. Testing the re-designed Boreas 3 alternator. The angular deflection is greatly reduced with the 12" shaft and bearing housing. Much smoother running and pushing into the 37% efficient range now.
Next up is to improve the supports and eliminate the guy wires, then streamline out any support drag.
How do you calculate the efficiency ratings of these things?

Look up Power in the Wind using the US-VAWT.com calculator for this sized Turbine (3' x 6') then compare to the volts x amps output.
