More Efficient Fan Blades Mimic Humpback FinsViews: 120

Interesting "kayak", Ron.

The wind turbine might take these blades a step further by adopting a linear electric motor/generator approach instead of the rotary electric motor/generator design we commonly think of. Having done this, the next step would be to consider other propulsion designs in nature. The marlin is the fastest swimmer in the ocean, using a single blade design. Perhaps it holds an advantage even over the humpback fin?

The flap as an alternative to rotary motion might be beneficial in regard to wind turbines posing a threat to birds, and might also offer aesthetic alternatives to those who don't like fields of fans.
