A big problem with all wind generators is what to do with the power when it starts to blow.
The Air Marine has fixed blades. It has its max power at 12,5 m/s, 400 W. When it starts to blow more than that, it transforms the power to “noise”.
It has been replaced with Air X. It has its max power at 12,5 m/s. When it blows more then 10 m/s, it shuts of. It has very little difference on the monthly energy sense it seldom blows that much.
There has come a newer version named Air Breeze. The biggest difference it that the blades are white. It still shuts of at 10 m/s but now they have taken down the stated max power.
All of these have fixed blades.
There exist a German wind generator
named Super Wind
. It has its max power at 12.5 m/s, 360 W. When it blows more than that it change the pitch of the blade and the output power remains 360 W. They stated that it shall remain 360 W up to 55 m/s !
