I remember another expiriment in the mid '70s. A vertical cylinder was rotated by a small motor. I believe lift was generated onthe upwind side. It might have been "Popular Mechanics."

It was tested as a stand-alone propulsion source and also improved fuel economy on a fishing trawler it was installed on.
