Photos of Vertical Axis Wind Turbines by Paul Gipe

Experimental straight-bladed Vertical Axis Wind Turbine at Risø National Laboratory, Roskilde, Denmark, 1980.

Experimental straight-bladed Vertical Axis Wind Turbine at the Kaiser Wilhelm koog test center, near Marne, Germany, circa late 1980s or early 1990s. The turbine was not operating when this picture was taken.

Pinson cycloturbine at New Mexico State University, Las Cruces, New Mexico, 1979. The turbine was not operating when this picture was taken.

Early Vestas experminetation with a bi-blade (phi-configuration) Darrieus. Designed by Birger Madsen. When this photo was taken in 1980 Vestas had alreday switched to what would become the classic "Danish" design of a three-blade, upwind, Horizontal Axis Wind Turbine.

Alcoa experimental three-blade phi-configuration Darrieus on the Oregon coast late 1970s or early 1980s. Alcoa later abandoned the technology and the design was spun off too VAWTPower.
