Fun read! Guess we'll all see if it goes in the marketplace.Ease of manufacture may be an issue.Thats some very sophisticated architecture. Pressure and velocity distribution could affect dynamic balance,and resonance ( flutter ) may affect structural integrity with high velocity applications, as there are so many local areas of impact,channeling,redistribution and discontinuities of aft-trailing -edge flow .Super-turbulence!Whales can articulate their flippers while turning,changing angle of attack at will as they pirouette in the water.The fluke of the whale is responsible for propulsion.I'd be more impressed if the tubercles were present in the fluke where the real power is laid down .Since whales communicate at extremely low frequency,could it be that the tubercles are "heard" by other would-be mating-age male whales and fertile in-season females,as tail-feathers are "seen" on the male peacock? Yep,I'm losing it alright!
