I know that this entry is a bit vague but I think useful as well. I just want to give it a start. Since aerodynamics are a demanding topic, I would like to leave more detailed descriptions to someone how is an expert on this (e.g. a physicist).

Could you please cite sources (apart from de:Repeller)?

de:Bild:WindCompilationW1.jpg can't be used directly, you will have to re-upload it here or on Commons. See Help:Images.

Ok, I will try to upload the picture and find some cite sources. Will links to webpages about wind turbines do it? —Preceding unsigned comment added by Lars-petter (talk • contribs) 13:13, 22 September 2008 (UTC)[reply]

Depends on what kind of web page it is - have a look at Wikipedia:Reliable sources. Regards, HaeB (talk) 13:19, 22 September 2008 (UTC)[reply]

Regarding cite sources:
What I found while google and yahooing for "repeller" was mainly (more than 20 hits) ebay auctions were people wanted to sell a repeller for home brew wind turbines. Scirus gave me an article about a wind-driven bird repeller (not really what I was looking for but a funny connection though). What I found via checking the googled ebay hits was, that the term is common among home brew wind turbine makers from Austria and Switzerland as well.
On pages of the german wind industry I could ONLY find the term "rotor". One reason might be, that the industry wants to address buyers of their products rather than engineers who might prefer a more precise but less common term. One manufacturer of small-sized wind turbines uses the term: "... als Repeller ( Rotor) läuft schon mehrere Jahre erfolgreich oder als Savonius..." This is the URL: [1].
One of the biggest German producers of wind turbines is REPOWER [2], but they might have chosen that name to express that their company stands for sustainable technology, in opposite to common energy sources like coal or oil. If I remember well, a german engineer I once talked to used "repeller" as well.
At least this can be said without a doubt: to repell comes from Latin repellere, from re-" + "pellere to drive (http://www.merriam-webster.com/dictionary/repeller) while propeller comes from latin propellere = to drive/move sth. forward.
Saying to repel wind force one could claim that it could mean to make wind to move away like a repeller against mosquitos does, but on the other hand a resistor is not making electric current to run away but lowers the voltage (and as a side effect e.g. emits heat or light while a repeller emits motion) as being a re-sistor.

Finally: As mentioned above the term "repeller" seems to be common in English in order to say something about applications used to keep animals away. With regard to that, it might be confusing to the reader to associate "repeller" with wind turbines (but then also compare with "rotor").
So, in order to keep Wikipedia a reliable source for information it might possibly be better to erase the entry. If it is possible keep it a few weeks to see what other people think, you may leave it for a while. At least the note "This article needs additional citations for verification" and "This article may require cleanup to meet Wikipedia's quality standards" should be added.
In case you think it is helpful, I will ad the latin terms from which "repeller" originates. —Preceding unsigned comment added by Lars-petter (talk • contribs) 15:57, 22 September 2008 (UTC)[reply]
