Yeah, those Altamont Pass wind turbines are pretty ugly--which means that under the "iron" law of fluid aesthetics, they are inefficient as well.  They also had lattice towers and so provided perches for birds who would then launch themselves into those rapidly spinning blades.

MOST of the wind-turbines-are-hazardous-to-birds story comes from those primitive turbines in Altamont Pass.  This is an incredible wind site--why hasn't anyone replaced those worthless pieces of junk?
