Wind Turbine Design Reduces Blade Size, Saves Money
December 3, 2008 11:10 am | by by Jason Lomberg, Technical Editor | Blogs | CommentsBetz’ Law (culled from its namesake, Albert Betz) is a theory for flow machines. From this theory we derive the Betz Limit, that is, “the maximum possible energythat may be derived by means of an infinitely thin rotor from a fluid flowing at a certain speed.” In windmills, this equates to how much electricity can be harvested from the wind energy. Current technology allows turbines to capture a maximum of 59 percent of the energy in wind
