What are the current commercial products that use bionics very well?

Think about it: When will we see wind turbines? I believe most of you are on the road! From a distance, the wind turbine silently turns its three enormous blades. He is really a calm and handsome man~ But if you can get closer, the wind turbine blades will still make a very rhythmic sound when they pass through the sky. voice. It's not very noisy, but many places have strict noise regulations for onshore wind farms, especially if there are people living nearby. Currently, in order to meet the requirements of environmental regulations, the wind farm must reduce the speed of the wind turbine to reduce noise, but this also means that less electricity is produced. Approximately every decibel of noise reduction reduces the power of wind turbines by 2 to 4 percent. To reduce the noise generated by wind turbines, our researchers turned to owls. Although the hibor has cute attributes, it is an extremely effective hunter at night, and its silent flight abilities are one of the reasons it is so deadly. In flight, the air circulating through the wings will transform into small vortices under the action of these “little saw teeth”, thus eliminating the noise caused by the air flow. Siemens researchers imitated this structure and improved wind turbine blades. Although not an entirely new idea, as early as 2002 we used a design called a "dinosaur tail" on the blades to reduce wind power noise. By adding this attachment to the blades you can significantly reduce the noise, but it doesn't fall into the category of bionics, it just looks like a dinosaur tail. Learning from Professor "Owl", we improved the design of "Dinosaur Tail". This new design combines the long feathered comb structure of the owl with the original tail of the dindinosaur. After testing, blades equipped with the new design can reduce noise by more than 10% compared to the previous product. This will make it easier for wind farm operators to meet strict environmental requirements without affecting energy production!
