Do you still remember the artificial bird created by Festo, the German company, a few years back? That remarkable innovation, which mimicked the flight of real birds, has now inspired a new breakthrough in renewable energy. Recently, Festo applied the micro-powered wing technology from their robotic bird to wind power generation, resulting in the development of a bi-wing wind turbine. This unique design features two wings that move up and down in an asynchronous motion, capturing wind energy efficiently. The wings generate lift as the wind passes over them, and this force is then converted into electricity through a complex mechanical system. What makes this design stand out is its ability to operate effectively even with a light breeze—Class 3 winds or above are sufficient to keep it running smoothly. Additionally, this generator is much safer for birds compared to traditional wind turbines, reducing the risk of collisions and harm to wildlife. In certain scenarios, this bi-wing system could potentially replace conventional spoke-type wind generators altogether. Its lightweight structure and efficient energy conversion make it a promising alternative for future sustainable power solutions. The design not only showcases the beauty of biomimicry but also highlights how nature can inspire cutting-edge technology.
As a common transmission force device, the stainless steel chain reduces friction through the "chain" design of the hyperbolic arc, and is used in places where the power is relatively large and the running speed is relatively slow, which has obvious advantages over belt transmission, such as Tanks, pneumatic compressors, etc., but the transmission speed can not be too fast, because the flexibility of the chain is not as good as the belt transmission.
