The currently existing design of wind turbines is incredibly stupid anyway, I have no idea how we landed on that design. It's one of the least effective designs possible for it's use case. We should be using spiral turbines.
The current three blade design of utility-scale turbines achieves about 80% of the Betz limit, are relatively efficient in materials for their output, and the blades' pitch can be adjusted to control their speed in varying conditions (eg. during storms). I wouldn't call their design "incredibly stupid".
That looks like it would be hard to manufacture and transport at the size requirements that traditional blades are made. It's already a massive pita to transport the traditional blades. I'm sure we'll figure it out eventually, but that's probably the current reasoning.
Yooo that looks sick as hell! Why aren't we using that?
Can you imagine how heavy one of those would be at full scale?
That's too futuristic and only belongs on other planets like mars
