Reminds me of the Voith Schneider propeller, here arranged to produce lift instead of propulsion.

hesham, please, read ALL the posted stuff :

"... The only aim Dr. Kaletsch had, was to prove by an experiment

That means, it was NO project at all (not even considered by the inventor himself) and so the apropriate
section is here. Theoretical and Speculative Projects.
