Flowind Vertical Axis Wind Turbines Eggbeater Darrius wind turbines at the Altamont Pass in Northern California, along hwy. 580 between Tracy and Livermore. These where set up in 1983-85. These unique wind turbines where removed in 2005 by FPL Energy and replaced with Vestas 660 KW machines instead. Similar machines once stood at the Tehachapi Pass wind farm near Mojave. Since they spin vertically, they did not need to face the wind like the propeller-type classic turbines, however, the bearings eventually give out, requiring replacement of the entire machine.
