Flettner himself built a test windmill, and abandoned the idea. Great info and discussion on rotors ( which actually worked in real ships, unlike Mr Leshes idea) at http://www.boatdesign.net/forums/boat-design/everything-old-new-again-flettner-rotor-ship-launched-24081.html where a new rotor ship has been launched and gone into production in Europe Unfortunately, both Rotors and the ‘Lesh’ system exhibit severe turbulence and vibration when incorporated in windmills.

Aeroplane wing designs apparently hmm If wind generators are only 32% efficient and this sail design is 4 times as efficient as normal sails wouldn’t this sail design be vastly better and less obtrusive as a wind generator, especially as it spins even in the lightest of winds when normal turbines do not?

But my comment is,like Pat, no news about this after 1933. I think is better than Savoniuos or Flettner devices. I still building a boat 19 feet in lenght using wave propulsion and I like to use also something like this. Please, if somedy knows about a web page with technical information comment here.

Was the full-size actually done? Does the magazine have a follow up story? I think there would have been ongoing coverage if a US man was improving on the prior work of others. I had seen the article before when I was researching the Flettner Cylinder Mast Sail. But I cannot find reports on anything other than the model as above.

One of our reporters went on the trip across the Atlantic on the thing and just went on and on about how new and unusual it was. No one believed me when I suggested something similar had been done in the 1930s but I had seen this article and another one like it reprinted back in the 1970s. Thanks for finding it!!
