Do you still remember the artificial bird designed by Festo in Germany a few years ago? Today, they applied this kind of micro-powered bird wings to wind power. Therefore, this bi-wing type wind-driven generator was born. Two "wings" move up and down asynchronously in the wind, and the lifting force generated when the wind blows across the wings is converted into electricity through a complicated mechanism. The most important thing is that even a Class 3 breeze can make it work normally, and it is also relatively safe for the birds. In certain circumstances, it can completely replace the spoke generator.
