I read somwhere, that in the nothern hemisphere, the gust veer to right (clockwise from above) and your post seems to confirm this. Thanks for going deeper into this thread.

  Don't forget to look at the effect on the blade that is 180 degrees from the one your obviously paying attention to (on the opposite tack, so to speak). IMO wind veering effects are nutralized between the top and bottom of the rotor irregardless of the direction of rotation.

  The furling effects are not ballanced with respect to flexing the blade into or away from the tower.

 All of the furling designs that I am aware of, have the tail furl in a clockwise direction when viewed from above so that a gust that veers in a clockwise direction(northern hemisphere) furls the tail rather than driving the rotor into the gust.

  With the tail furling clockwise from above a counterclockwise rotor rotation (viewed from upwind)drives the bottom blade away from the tower when the machine furls. The new Bergey designs and all of the Jacobs (old DC and new grid tie) have counterclockwise rotating rotors. If tower clearace is large enough this is a non issue. The Whispers rotate clockwise, but this may make their furling dynamics smoother IMO(not tail hinged)

 Any Ausies sp?  reading this. What do you see in your country? Come to think of it, the AWP turbine made in South Africa,but designed by a northerner, hinges the tail in the clockwise direction and if I remember correctly has a clockwise turning rotor as do Hugh's other designs (because if I'm quoting correctly ccw "just ain't right") Please join in Hugh, we would love your input
