Talk:Unconventional wind turbines

I copied a paragraph from the Wikipedia article Airborne Wind turbines. — Preceding unsigned comment added by Touftoufikas (talk • contribs) 10:00, 25 February 2023 (UTC)

wells turbine

What about the wells turbin invented by Alan Wells in the late 1980s? Should it be stated here? --HAH 06:52, 8 May 2007 (UTC)

maglev turbine

This is just a vertical axis turbine concept that seems to be based on very shaky math at that. Does this belong here? It seems like commercial promotion. —Preceding unsigned comment added by 128.200.20.56 (talk) 21:49, 5 September 2008 (UTC)

Given the overwhelming commercial and practical success of the conventional horizontal-axis, three-bladed wind turbine, all other designs will range from marginal to dubious by comparison - unless and until someone invents an unconventional wind turbine that can outperform the conventional design. However, lots of people have been tinkering with wind turbines for a long time, so the odds become steadily lower that everyone has overlooked some good idea. Lower odds, but not zero. Therefore, in my personal opinion (which carries no weight), this article should cover even speculative wind turbine designs that failed in development. Better to group the also-rans here rather than having them gum up the "proper" wind turbine article. Even failed ideas can be worth studying, if only to learn why they failed, so the next tinkerer does not repeat the same mistakes. --Teratornis (talk) 19:53, 2 November 2008 (UTC)

This isn't even really an unconventional turbine so much as an unconventional means of supporting the rotating shaft in a turbine. Still, this page is probably the best place for this sub-topic. Merging page Maglev wind turbine into this page - in the process, removing the unverifiable and irrelevant, and recombining the remaining text to be somewhat more coherent. Still needs some work, I'm not sure how to approach the second paragraph. --Digitiki (talk) 05:12, 9 October 2009 (UTC)

I took it out. It's not aerodynamically a different type of turbine, and mag-lev bearings coudl be applied in any type; plus the whole thing had an inscrutuable air of hoaxiness. It's been a couple of years and there's no traction here; it can be added if one ever gets built. --Wtshymanski (talk) 15:37, 11 August 2010 (UTC)

Wind turbines on public display

I expanded the "Observation deck" section to be a subsection of a new containing section: Wind turbines on public display. Since wind turbines are becoming tourist attractions in some parts of the world, the list could grow. Eventually we may want to spin the lists into a separate article. All of the wind turbines on public display I have found so far are of conventional horizontal-axis, three-bladed design. The unconventionality of these turbines is not in their design, but in their presentation to the public. However, as public interest in wind power appears to be growing around the world, perhaps in the future most wind farms will have some sort of visitor centers or viewing areas, making this aspect less "unconventional." In that case, a separate article for wind turbines on public display would be more suitable. --Teratornis (talk) 19:53, 2 November 2008 (UTC)

I've moved it to a separate article. DexDor (talk) 20:05, 29 March 2011 (UTC)

Rotorsail

Shouldn't a rotorsail with dynamo be mentioned too. The rotorsail is special and should be mentioned as it uses a specific extra force of nature —Preceding unsigned comment added by 81.245.82.134 (talk) 11:08, 27 July 2009 (UTC)

We can mention whatever you can reliably source. The Rotor ship article only discusses powered rotors. I don't see anything about passive rotors of this type which would count as power-generating wind turbines. Do you have a source for what you are talking about? --Teratornis (talk) 17:00, 27 July 2009 (UTC)

According to this source:

• Salter, Stephen (2008-11-13). "Sea-going hardware for the cloud albedo method of reversing global warming". Phil. Trans. R. Soc. A. 366 (1882): 3989–4006. doi:10.1098/rsta.2008.0136. Retrieved 2009-07-27. {{cite journal}}: Unknown parameter |coauthors= ignored (|author= suggested) (help)

there is a proposal to build rotor ships that would be entirely powered by the wind. However, the Flettner rotors would not generate power directly, but instead would require power to rotate them. The source of power would evidently be the ships' screws which would turn passively as the Flettner rotors generate propulsive force which pulls the ships through the water. The power to turn the rotors would evidently be less than the power the screws could harvest in water turbine mode. Thus I wouldn't consider the Flettner rotors to be an example of an unconventional wind turbine, but rather an example of unconventional ship propulsion. I added a link to the {{Application of wind energy}} template. --Teratornis (talk) 03:26, 28 July 2009 (UTC)

Warning

Firefox reports the link in section 2.3 as an attack page — Preceding unsigned comment added by 68.110.29.51 (talk) 00:57, 30 October 2012 (UTC)

Saphon 'bladeless' turbine

I removed the section for this, as the claims were made two years ago and have not been additionally supported, at all, since. An efficiency that high would violate Betz's law, something they claim doesn't apply to their turbine in particular in the patent for the device - "This system is not subject to the theoretical Betz limit" - with no explanation whatsoever.

The citation in the section originally doesn't even really count as a citation. So, deleted. Aklyatne (talk) 01:38, 16 March 2014 (UTC)
