Why Not 2 or 4? Why Three Blades Beat Every Other Wind Turbine Design [ID0821]

Описание: Have you ever wondered why almost every wind turbine you see has exactly three blades? It’s not random — it’s the result of physics, engineering, economics, and even human psychology. In this video, we break down the science behind turbine blade design, explore why one- and two-blade turbines failed, and explain how three blades became the perfect balance for clean energy generation. By the end, you’ll never look at a wind turbine the same way again.
