Vertical axis wind turbines are provided having foil design and geometry that facilitates lift, torque and laminar flow along a 360 degree radial. Contemplated foils are non-planar, and have a chord length that is at least three times greater than a distance between a trailing end of a leading foil, and a leading end of a trailing foil. Additionally or alternatively, the foils are located away from a turbine axis at a distance that is about 2.9-3.5 times greater than a chord length of the foils. In some embodiments, the foils are circumferentially distributed via one or more laminar stall vanes.
