Could not get past the obnoxious ads.

  I see zero ads in the mobile version.

  Likewise, completely unusable on a mobile. The whole page took ages to even render (on wifi) only to instantly start jumping around to fit in ads.

Marvin Antelman is a crank, with a fondness for loony patents and a unshakable belief that his special silver compound can cure cancer and AIDS: http://www.rexresearch.com/antelman/marantech.htm http://www.rexresearch.com/antelman/marantech.htm http://www.rexresearch.com/antelman/silverox.htm http://www.rexresearch.com/antelman/silverox.htm Fortunately, he'll sell it to you for only $15 a gram.

  I don't feel this reflects on the article itself, although a better link would set off fewer red flags. I think the article "looks more legitimate" as an archive.org link to the experimental aircraft association web site: https://web.archive.org/web/20140416074216/http://www.eaa.org/experimenter/articles/2009-02_elippse.asp https://web.archive.org/web/20140416074216/http://www.eaa.or...

    Oh! So this submission is just a pagerip of someone else's content? I hadn't noticed that.

      Yep. Totally reasonable to be dodgy about a link on a crank site. Engineering looks legit to me though (I have zero experience in the field). That said it's gone from the site, although the author has posted a bunch of articles.

Mechanisms on this scale would seem relatively easy to test and compare. He's trying so hard to sell all the positive qualities of his propellors..... if they are so awesome, wouldn't they be easy to sell?

I put Paul Lipps in the original submission title since he was the original author. His web page is not up anymore, so it's on some less than reliable site. The moderators' change lost that info. It's related to the popular article by Robert X. Cringely. He advocated Lipps' ideas for wind energy, with previous discussion here: https://news.ycombinator.com/item?id=11643410 https://news.ycombinator.com/item?id=11643410 Sadly not realized after Lipps died. However, with Lipps describing his thought process here, it seems likely that it would be possible to repeat it / learn from it. I guess optional comment fields for links have been considered and decided against.
