Do i understand correctly the video from 1, wants to make a propulsion system out of a spinning rod to leverage the Magnus effect? Why ??? It is awesome! Also

Do i understand correctly the video from 1, wants to make a propulsion system out of a spinning rod to leverage the Magnus effect? Why ??? It is awesome! Also I know that the algorithms are often tested against wind tunnel experiments, but wouldn't the implementation also be worth the test? There are many demons I can think of between the numerical algorithm and their implementation. Great job! I loathed working in the field of CFD due to its penchant for old Fortran and non engineers doing IT tools.
