6. Improving aerodynamics based on whales?: Scientists and engineers in 2004 came together and published a paper that had surprising findings. Apparently, the bumps on whales’ fins allowed them to achieve greater lift with lesser effort. Although the idea of seeing airplanes with bumpy wings is yet to prove itself, a company called WhalePower used this concept in its wind turbines, noticed that bumpy turbine-blades inspired by tubercles on whales’ fins reduced drag and allowed. Since the blades spun even at lower wind speeds, there was more power generation with less wind.
