Sketch
looks like the artist sketch has the wind backwards.69.163.56.66 (talk) 17:59, 9 September 2011 (UTC)


 * It looks that way but the sketch is correct. What happens is that the wind (coming from left) pushes against the ring, which bends the air away from the center of the stream (creating a low pressure zone behind the blades), and the low pressure makes the blades spin faster. Watch the video (see external links) and it perhaps explains it better. Cool idea.--Tomwsulcer (talk) 18:40, 9 September 2011 (UTC)

--Hot cake syrup (talk) 00:55, 16 February 2012 (UTC)==Notability and uniqueness== Is this a notable concept? The refs are pretty slim. This one barely mentions the concept. This one has a single sentence. This is a very short profile. That doesn't appear sufficient for a standalone article.

Separately, this seems to be essentially the same as Ducted propeller or Ducted fan, albeit used to produce energy rather than thrust.

Either way, perhaps it'd be better merged into Wind turbine, as it's simply a minor variation.  Will Beback   talk    21:45, 13 February 2012 (UTC)
 * Or even better, Unconventional wind turbines, which already has entries for variations like this.   Will Beback    talk    21:51, 13 February 2012 (UTC)
 * I support merging into Unconventional wind turbines ErnestfaxTalk 14:59, 14 February 2012 (UTC)
 * I also support merging into Unconventional wind turbines. Johnfos (talk) 16:15, 14 February 2012 (UTC)
 * support merge. This doesn't appear to be an original concept. It looks to be a ducted rotor type, invented way back about 1885. --Aflafla1 (talk) 04:22, 15 March 2012 (UTC)
 * Actually, I've changed my mind. I think the article is non-notable and should be deleted. See this article by Paul Gipe. --Aflafla1 (talk) 04:49, 15 March 2012 (UTC)


 * I think Wind lens has original structure against other windmills, and many plans have recently been announced to construct wind mills over the Hakata bay. Then this article should be independent in Wikipedia. --Hot cake syrup (talk) 00:55, 16 February 2012 (UTC)

The Problem with Ducted Rotors
This is a variant of a ducted rotor. The problem with the design is that by the time you add the expense and bulk of the duct around the rotor, you could just as well have made the rotor larger in diameter by a significant factor and skipped the duct. You'd get as much power improvement that way as by using the duct, but at less expense. --Aflafla1 (talk) 21:25, 19 January 2014 (UTC)
