7. Humpback Whale Flippers and Wind Turbine Blades
The bumpy edges on humpback whale flippers, known as tubercles, provide exceptional maneuverability by delaying stall and reducing drag. Engineers have applied this concept to wind turbine blades, enhancing efficiency and reducing noise. For instance, incorporating tubercle-like bumps into turbine blades has been shown to increase lift and decrease drag, leading to more efficient energy generation.
