At Home in Deaf Culture: Storytelling in an Un-Writable Language

These days I’ve got three languages rattling around in my head: English, Croatian, and American Sign Language (ASL). (There was a point at the start of college when I could read novels in Spanish, but that muscle has since atrophied.)

Why wind turbines have three blades

The conventional answer to this question is that three blades minimizes the shadow effect that each leading blade has on the blade that follows. You want more blades to reduce the starting torque required to get your turbine spinning (this is analogous to having more cylinders in an engine making it run smoother) but if you have too many blades the shadow effect hurts efficiency and drops the total yield. Three blades peak at about 48 percent efficient, which isn’t 59.3 percent but is near enough and happens to be the practical output I mentioned two paragraphs ago. So it must be right, right?
