Hi everybody
While surfing the net, I came across this wind turbine which seems quite easy to achieve.
It has very little drag and it is possible to vary the opening by tilting more or less one of the two axes.

Remondo, tell us what you think.
Vertical wind turbine
Hi Alain,
Thanks for the link, I did not know.
It is a wind turbine based on a differential drag. The kinematic concept is very successful.
This wind turbine works on the impact of the wind with a large lever arm: it will be at high torque, moderate speed, and at ease from low wind speeds.
But my heart is leaning towards the ROBIPLAN

New type of Basque wind turbine.
Chai not what is its yield but it is by far the most beautiful ...

Reason is the madness of the strongest. The reason for the less strong it is madness.

Particularity of the Basque pelton, it returns the balls faster than it received them ... well, it depends on who you put in the maneuver.

Hello Rémundo!
Indeed the couple in light wind must be quite interesting, when we know that strong winds are rather rare, it becomes an interesting alternative.
I recently bought a robust antenna mast of almost 20 meters for my parabolic antennas, I think developed a proto on this principle, the mechanical part is relatively easy to carry out, it remains to carry out the control to close it by strong wind but I have my little idea: with the help of a micro-controller and a rotation sensor.
The orienting part can be done by a large rudder or controlled by a motor.
By keeping the bottom axis fixed and only rotating the top axis, it becomes much easier.
I have all the necessary equipment for the realization.
Tell me what you think.

Hello Alain,
I would prefer to avoid enslavement to the direction of the wind.
A well-placed board will naturally place the machine in front of the incident vein of fluid, "weather vane".
For the mechanics, I let you judge. Sometimes, we bother to fold the blades while surrounding them with a cylinder (of the same axis as the mast) sliding can protect them simply.
For some robust vertical rotors, it is enough to block the rotation and wait until the storm passes ...
Good cogitations
