Why Wind Turbines Have Three Blades
This is a classic example of sub-optimization (and even if it&#x27;s hand-wavey pseudo-science and may be wrong, the general concept is still interesting).<p>Each individual wind turbine is optimized to be the &quot;most efficient&quot; it can possibly be.<p>But not in the context of the environment, which requires complex control systems and methods to reduce damage in non-optimal conditions.<p>And not if you take cost and efficiency of the whole system into account; where four times as many small turbines with less complexity run more often and produce more overall output.<p>But hey, each wind turbine is &quot;optimal.&quot; Interesting.<p>Most complex systems have this property. Even (especially?) your business.
