How To Make A Radio Control Plow

arguments proWIND

wind power, what is it?
from wind power. As with a bicycle dynamo generates the rotation of the wing power - as simple as that

Does that sound?
The wind turbines generate noise. Of course - the wings rotate in the wind, producing the typical "flapping" sound. The volume is limited by law. The turbines may in the building that is closest to the wheels, only 5 decibels louder than the quietest quarter of an hour of the day. So that means if you drive at night only to hear distant cars, may the wind turbines are only minimally audible. A sound pressure level of 10 decibels corresponds to distant rustling of leaves

Why the wheels must be so high - we indeed is also no wind
These two arguments belong together. Low wind turbines generate less power. Not only because they have less "power" have (small = less Capacity) but also because they do not use the wind correctly. The air above us, "ordered" in layers - below a certain level of turbulent wind is blowing, that is no continuous flow. Only at a certain level this occurs, laminar flow on. In this level we have very good wind conditions, which are exploited by higher wind very well.

Why just us? We can still carry electricity throughout Europe
Yes, there is a European power grid, but there is at present the biggest problem is that the capacity is not enough to the stream without problems from north to south, from east to transport to the west.

wind rotifers
disturb for a wind turbine has to be made a so-called environmental impact assessment, this is primarily what the impact on soil and animal concerns in great detail. In animals, experts can often determine damage. In addition, local residents and hunters report that wild animals return shortly after the construction of wind turbines and again, usually paid by the operators to use wind protection belt you.

What happens to the wind when there is no longer the operator?
is basically formed during the operating period of the windmill, a reserve, which guarantees that the wind turbine can be reduced according to the operation or for other reasons.
If it returns a "skeleton" in the landscape?
No, wind power plants will be built remains. The concrete foundation is eroded and filled in with earth, the surface is then again as originally exploited.
Is not wind power expensive?
Bei der Windkraft werden heute 9,7cent pro Kilowattstunde bezahlt. Diese 9.7 cent bekommt der Betreiber, ähnlich der Förderung für Photovoltaikanlagen. Insgesamt machen Kosten für Ökostrom (Sonne, Wind, Wasser) 10,7 Prozent des Strompreises aus (davon 2,1% für Kleinwasserkraft, 3,9 für Windkraft, 3,6% Biomasse, 1% Biogas…)

Ist Windkraft umweltschädlich?
Leider existiert keine Möglichkeit, Energie zu erzeugen, ohne dabei Schäden anzurichten. Windkraft macht aus Wind Strom den wir nutzen können. Der einzige Schaden, den das Windrad anrichtet, ist dabei der, dass es Menschen gibt, denen es nicht gefällt, dass das Windrad in der Landschaft steht. Das ist aber eine Geschmacksfrage und darüber lässt sich bekanntlich streiten.

Erzeugen Windräder schädlichen Schall („Infraschall“)
Infraschall ist besonders niedriger Schall, außerhalb des Bereiches,den Menschen hören können. Unterbewusst kann es jedoch sein, dass Menschen diesen Schall spüren können (ähnlich Vibrationen bei Bässen). Infraschall wird von Kühlschränken, Autos und vielen anderen Objekten erzeugt. Es gibt bisher keine wirklich zuverlässigen Studien zu diesem Thema, die einen Schluss auf die Schädlichkeit the generated infrasound from wind turbines (if it exists in the form) permit. But the fact is that the critics always rely on information from Germany, the USA and UK. Here are the distances that the turbines have to comply with settlements but down many times. A particularly critical study refers specifically to a recommended distance of about 2km. This is roughly the distance that should have the windmills in Hausleiten, Russ Bach and Sierndorf (1.8 km). Even in this, especially critical if there is not a problem.
