...(continued)...before charging. It may spin for days or weeks without ever reaching that magic speed. The lift wings tend to run away, restrained by the alternator load. So in light winds, the lift wings will produce the power available, where the drag wings may never reach the cut in speed. In heavier winds, the lift wings produce power consistent with the wind input..where the drag wings begin to fall. The lift wings spin fast! and require the robust and precise R2-40 rotating assy.
Caleb, this is a lifting wing, whereas the Lenz IIs are mainly drag style. We see much more power and performance from these wings at all speeds when compared side by side with the Lenz II. The drag style wings have have a self regulating feature/flaw that limits the rotor speed regardless of the wind speed due to the drag on the upwind side of the VAWT and >1 TSR. This doesn't allow them to follow the cubic power of the wind speed. Also, the drag design relies on a specific wind speed...
@magna59 Thank you for the note. The wind speeds in the video were in the 20-30mph range and were very gusty and impossible to capture meaningful speeds with corresponding power outputs. You can see how fast the power values change, the wind speed changes even faster...so it is tough to capture both at the same time with accuracy worthy of publishing.

How does this turbine compare with your other turbine with the Lenz2 style wings?

Same question ..... great vidi .......brisk movement, but what's the wind speed ?
