Hi Paddy,
I am not sure what the advantage would be of your system? I am not sure whether you understand that the furling tail in my design protects the turbine against excessive winds by allowing it to turn away and thus preserve itself from destruction. I am not sure what to make of your comment at all in fact but maybe others will get your drift.
I hope so.
Hugh
make the frame wide enough to allow for full movement and avoid the tail fins clashing.
hugh,
we are being taken the piss out of
put the small turbines on a light welded frame,both turbines facing outwards with a directional fin on the back of each like a weather vane.
make each turbine on a swivel/pivot free movement system of just over 180 degrees.
if both turbines on the single unit both on their own magnet generator are facing opposite ways outwards and just over 180 degrees of movement,you’ll get the full 360 degrees of movement and 1 turbine at least will always be facing into the wind.
also,make the turbines as light as possible to allow roration even in the lightest of winds.
regards,
paddy 🙂
