Can you look at this wind turbine and give me your comments.

Family wind turbine 5k watts comment from Rémondo SVP.
Hi Alain,
We invite my comments, like the big men on TV
What I can say at first glance:
- it is a differential drag wind turbine
- periodically, it deploys and returns its blades to the wind.
- it is a vertical axis wind turbine.
To tell you the truth, it reminds me a lot of that of Eolprocess

This page is not bad

It shows the orientation mechanism of the blades ... it smells like the epicycloid

all these vertical axis wind turbines are fake simplicity
when sailing with a sailing boat you understand very quickly that the same sail cannot be effective in all directions: it is in crosswind that it gives the most power
downwind is bad: you have to increase the surface to the maximum to have less power than a smaller sail across
of course from the headwind it's skillfully zero
in crosswind it can advance faster than the wind: so if the blade works well in crosswind in this kind of wind turbine, it will be completely zero in the downwind part
there is no wiggling of the ass to shit straight: the good wind turbine or the blades always make cross wind is the classic wind turbine that we see everywhere
the classic wind turbine is the one that gives the most power per kg of material used
it is also the one which gives the least effort on its support: I am always surprised to see advising the wind turbine with vertical axis on the roofs of the building, it is the one which make the biggest effort and there has no solution to reduce the effort in case of too high wind
the classic wind turbine makes power and gives a big effort on the mast when it turns well: the effort depand on the surface of the disc swept by the blades and not on the surface of the blades: when the wind is too strong it is enough to stop it so that the effort is much lower

Hello,
There are simple things about wind turbines that deserve to be remembered often.
This wind turbine has a surface of 2.7 m²
The power of the wind in this surface is:
at 10 m / s => 1/2 xmx S x V x V x V => 1388 Watts
Assuming a yield of 30% (drag type wind turbine) this gives a useful power of 416 Watts
It is therefore of the 500W class, which is far from meriting such a complicated construction. It is the equivalent of a well-known Air-X .....

I would use toothed belts instead of gears, much more flexible to use, less noisy and no lubrication.

chatelot16 and Obelix
Study this wind turbine well, for three days that I have been working hard on it and I believe that it can deliver a lot of watts for a reduced location, it slows the air flow to the max and withdraws a lot of torque, there are 2 blades still working on 360 degrees and 3 on a good part of a turn. Propeller wind turbines have much less drag, so recover fewer watts.
In addition, they do not use any air gaps, only coils and magnets, no reducers, belts or others.
