How do you design ocean turbine blades for optimal performance? Some scientists propose building them in imitation of whale flippers:
"We designed a novel blade modification for potential turbine performance improvement, which was inspired by humpback whale flippers, with the addition of tubercles, or bumps, to the leading edge of each blade," explains Mark Murray, a Naval Academy engineering professor. Previous research demonstrated the addition of biomimetically derived protuberances (technology that mimics nature) improved stall characteristics and aerodynamic performance."
A startup company called WhalePower is already at work trying to find commercial applications for these new designs.

There are plenty of examples of imperfect evolution such as the way that our esophagus and wind pipe are right next to each other, creating a choking hazard.
For all we know birds will evolve bumps on their wings in the future. Or perhaps bumps only improve aerodynamics in water.
Surely the bumps would help them fly farther with less energy and help predator birds fly faster to catch their food supply. So, what happened there?
