are as high as 35% for three-dimensional vertical-axis turbines like Darrieus or Gorlov turbines (see below). Windiness varies. Generally, the average wind speed for a particular location is
used for pumping water, and the vertical-axis design, like the eggbeater-style Darrieus model, named after its French inventor. Most large modern wind turbines are horizontal-axis turbines

Although there has been some experimentation with vertical-axis wind turbines, most wind turbines have airfoil-type blades that rotate around a horizontal-axis. The blades are designed like the wing
Benjamin Bell: While at the University of Massachusetts, Ben worked with Professors McGowan and Cromack on wind and solar heating systems, as well as Vertical Axis Wind Turbines. Ben is now a chief
