Wind Reviews Futurenergy Windup 1000W

[Forhorse]

I'm going back to this subject to tell you that I have finally assembled and installed my wind turbine. Since the time it was in the boxes!

The assembly is super simple.
Balancing is a formality since there is nothing to do. The manual says that you have to add nuts until you have a perfectly horizontal propeller, but since this is the case without adding anything just check what ...



And there it is installed ... temporarily ... with everything you should not do for a wind turbine: the mast is too short and barely protrudes from the vegetation, there is no guy, and the electric cables have too small a section ...


And of course, Murphy's law requires, the day I install it there is not a breath of wind!

and it's not over:
the first day it's going to rain, you're going to get lightning on it.

Bird of doom !!!
The strong wind will arrive well before the lightning and therefore after guying against the wind, it is enough to connect the pylon to a good deep and wet earth plug with a very large copper or aluminum rod (1cm2 of section) above the wind turbine to channel lightning towards the ground and thus have a beautiful lightning rod !! !!

[chatelot16]

it is not the day or it will rain that lightning will fall ...

thunderstorms most dangerous for lightning are thunderstorms without rain

[Forhorse]

Earthed or not, I think if lightning strikes this kind of wind turbine, there won't be much left!

[chatelot16]

lightning explodes a tree because it is just conductive enough to attract it and really not conductive enough to let current flow

with an iron mast and a metalic wind turbine also it can bear a lightning strike ... of course nature can be very strong and make very big love at first sight but it does not happen every day

[dedeleco]

Lightning falls with a lot of luck, but having received lightning on my house, I noticed that it chooses, so close to its path, the minimum resistance and the minimum Rac (L / C) impedance; so copper or aluminum better than iron (except very large section of iron 7 times more) and large short wires (low L) and max surface of plates (low C) therefore large metallic masses !!!
The minimum resistance must also be that of the connection to deep earth (therefore wet over a large area)
So if the wind turbine is shielded with metal, it will resist, because the current flows on the outside surface and not inside.

The probability of lightning strikes is a few hits per km2 and per year in France.

A little up of this subject to report the posting of videos showing this machine in situation.
Today almost a storm condition in Normandy, the weather indicates gusts at 85km / h, in my opinion given my situation (at the top of a hill, without obstacles) I must have more.

The installation is once provisional, not to reproduce
This summer, when the weather will be milder, the mast will be carried on the large gable, history that the wind turbine does not undergo the turbulences which it causes.
I will also use a mast with a larger section and stiffen it, and possibly stay it.

Under these conditions the production is low (from 20 to 80W approximately) but continues!

I look forward to being able to install this machine properly to finally know what it is capable of.

How the drift behaves when attached
Without cable, just put a very rigid axis across at 2/3 the height as for boats. Don't have the cables in the water
Like that, at the bottom of the photo clearly visible

: shock: How the drift behaves not attached

It's all the subtlety of this system, but it looks effective.
In fact the axis of rotation of the fin is not horizontal but inclined. When the wind is in reasonable proportions, the weight of the centerboard causes it to stay aligned and "lock" in its normal position.
As soon as the wind is too strong, the force on the drift becomes preponderant in front of its own weight and it therefore pivots to offset the propeller.
As long as you don't have the machine in your hands, it's a bit complicated to understand, yet it's simple and effective.

Putting a strut would actually be a solution to calm the mast a little. But it bothers me to spend time for that when I already have the preparation for a better installation to do.
