claims that the tuburcles on the leading edge of whale fins actually
improve efficiency in fluid by lowering stall speed. I expect someone
here might have a good sense if this has any likelihood of working.




I'm not so sure, Richard. I remember about a decade ago there was an
independent double-blind study done on the aerodynamics of humpback whales.
Best they could achieve was an L/D of about 0/1 when dropped from 10,000
feet.

But they did achieve a successful calibration of the Norden
Whalesight.
