Hi Doug,
I tried to gather some crackpot features (Magnus rotor, Darrieus turbine, reeling).
More seriously (?) the figure 4A represents a Darrieus rotor (460) around the (not reeling) Magenn balloon https://patents.google.com/patent/US20060251505.
In a similar way, but not as an AWES, the figure 53 on http://students.iitk.ac.in/projects/wiki/lib/exe/fetch.php?media=2014:seifert_flettner_apps.pdf represents an Hybrid rotor comprising a cycloidal propeller around a Flettner rotor.
