AeroCube, the roof wind turbine

Image

While reading my favorite militant magazine, I came across an article about this wind turbine: theAeroCube.
It fits nicely to the roof.
Thanks to the slope of the roof, added to a venturi effect of the walls of the chimney, it starts with the slightest breeze.
The rotor does not fear a strong wind.
Restriction: only one preferred wind direction.

Aeolta is a Strasbourg company.

I'm leaving you, it's going to be the hour of the apérocube

:D

Hello,

WARNING !!!
This wind turbine is quite pretty and aesthetically pleasing to watch.
But from the technical point of view it's a real disaster.
The recovered power is "peanuts" and out of proportion with the asking price.
The surface exposed to the wind is of the order of 1M² the efficiency of the rotor is of the order of 20%, which gives us a power of 150 at 200 Watts.

So, inquire seriously .....

rooftop wind turbine without mat

good evening, I found another topic on top
https://www.econologie.com/forums/une-eolien ... t9373.html

as it was said, the only drawback is the direction of the wind, but hey I think that if it was invented it was tested under certain conditions

The lack of orientation is indeed a big problem: if we favor the prevailing winds for the establishment of the house we risk losing in climatism ... except the potential "nega-energy" of this last point is much more important than what the wind turbine can never produce ...

Possible solution: the orientable house : Mrgreen:

Me it seems to me original is aesthetic.
The rest…
I would not go buy it, but try to do it, if I wanted to.
I would add a plus: a vertical pivot in the center.
Going up the retractable chimney made of the roof and turning it half a turn, then reintegrating it to the roof, it would face the wind opposite.
We could do it also in the four cardinal points ...

Yes, Christophe ! it's better to turn the wind turbine than the house.
(You remind me of the Belgian history, where you need 5 people to milk a cow, including 4 who raise the cow by holding it by the feet)

Ah yes, OliSorry, I did not remember this post anymore. Where, at least, he had to make his way through my gray meanders ...

Yeah, you remind me chimney extractors, shaped fins balls with empennage to guide them. (It has a name, but I do not know which one)

Hello,

I go back on this subject.
Interested by the Aerocube, I conycaté in 2010, then several times in 2011 the aéolta sté which answered me that it takes into account my request and would put me in relation with their local distributor as from the creation of the distribution network .
Today, I discover that www.aeolta.com no longer exists and there is no way to contact the creator of the product!

would you have any information?

the problem of the wind is that there is not every day: if in addition this system uses only the wind which is in the good sense it is even worse

all those who worked seriously with the wind turbine know the wind is stronger and more regular at the top of a mat than a roof razor

wanting to join the roof is a mistake: too expensive and too little power

for a good efficiency it is necessary a mat 2 times higher than the height of the obstacles: when there is a house of 6m of high it is necessary a wind turbine has 12m of the soil

when there is a house 12m high it takes a wind turbine 24m ... if we limit ourselves to 12m possible without authorization, it works too bad! it's wasting material

thank you for the clarification

However, that does not answer my question: what about this sté?

Hello, it makes me think of something, if there is not every day of the wind, we could perhaps pull something chimneys extractors, which work by principle of rising heat, much like the carousel delighted with the candles that turn the propeller

so we could train an alternator with the chimney extractor, which is also used for wood stoves, it can be interesting in the cold regions but not very profitable in the south
still have to see if we can draw power with this system
