But Siemens, which makes many of the wind turbines popping up on horizons around the world, has created a suite of new products that makes turbines more powerful and is inspired by dinosaurs. It’s like something a 5-year-old thought up, but better. The company has created DinoTails and DinoShells. The DinoTail is based on the plates that line the tails of stegosauri. Here’s how it works, according to Treehugger : When applied to a wind turbine blade, they increase the overall area of the blade to add lift. The serrated edges help break up air flow around the blades, which decreases turbulence and makes the the turbines quieter while reducing the strain on the blades. The DinoShells’ dinosaur connection is less convincing: The idea is that the curve of a blade resembles a di...
