This complete weather station is very remarkable for the price !!
The recordings must be average and give the max in gust (gust level) probably!
A windmax of 150KM / h is rare especially in a clearing surrounded by trees !!
These are whirlwinds of a few seconds rare (enough to demolish a roof 160Kg by m2 !!).
On the other hand a wind in a clearing is weak, even with a valid wind on the heights,
except arrival of vortices and therefore the wind turbine can not be effective.
In addition, a sail, a wind turbine blade, an airplane wing, a windsurf sail, in a very turbulent wind has no lift !! (or at least very small) and an elongated blade wind turbine greatly loses its effectiveness at the same apparent wind speed, if it is very turbulent like behind trees or walls!
Having made the
windsurfing in the mistral fort coming from the ground, we come back easily from the sea
(a pleasure it goes on) but a few hundred meters from the edge with hills, the
turbulence and swirls become very strong and the closer you get to the edge, the harder it is,
lift of the sail, to wind up the wind reduced to little, and the more we struggle with falls in the water, if we do not know how to guess the whirlpools on the water of the sea and position the sail accordingly and keep its balance with a sail that turns in all directions and even projects you in water !! Once in the water we drift quickly to lose all that was won, as long as
we did not understand the mechanics of vortices !!
Some panicked had to be rescued !!
Also a classic wind turbine with elongated blades, with mostly whirlpools, always true with obstacles around, walls, trees, (far enough, 2 to 5 times the height or width of the obstacle)
will work much worse in recovered energy, than expected for the measured wind speed measured !!
The ROBIPLAN more in strait should work better !!
Mounting the mast does not only increase the wind, it dramatically decreases the turbulence by increasing the efficiency by the fineness of the blades (length to width ratio up to 50 on glider)
One must have windsurfing and return to the powerful mistral, to appreciate with his body, his muscles, and even with anxiety, all the fundamental importance.
it would take a small anemometer really cheap to put several on the same mat at different heights and record everything
A simple solution is a wind vane with anything (horizontal plate, drilled flexible tube), raised especially as the wind speed is strong, coupled with a cheap position or rotation sensor, potentiometer, optical, effect Hall with magnet, or even cheap camera taking a picture per second of all anemometers at a time, etc. for a few € !!
