I took out the reference to the Alcyone because the small amount of technical information I can find online (from reasonably canonical sources - the Cousteau Society mainly) about the Turbosail suggests it does not use the Magnus Effect. See, for example

http://www.limsi.fr/RS2005/meca/aero/aero11/index.html, a study about aerodynamic simulation which discusses the turbosail and includes a description as well as a photo of the inside. It's pretty clear from the picture that the thing doesn't rotate.

See also http://www.cousteau.org/en/downloadfiles/alcyone_and_turbosail.pdf, which describes the device again, albeit with a terrible picture.

[edit] Stated performance of Flettner rotor

It would be interesting to know the source for the statements in the article about the performance. To sail at such small angles to the wind as 20 to 30 degrees is quite difficult and I think even a very efficient sail like a wingsail that can also point extremely high would require something better than that particular hull under it to get up to those sorts of angles.

I've had a quick look on the net but found no extra material that might clarify.

Does anyone have access to a primary source?

[edit] Environmental technology template

I'd like to replace the Environmental technology template with one that matches the standard navbox style, i.e. horizontal instead of vertical, collapsing and typically placed at the bottom of article pages. I've done a mock up of what this would look like at {{User:Jwanders/ET}}. Figured this was a big enough change that I should post before going ahead with it. Please discuss here--jwanders^Talk 22:03, 17 February 2008 (UTC)
