A windmill with a vertical-axis rotor having thrust vanes which is surrounded by a stationary cage having guide vanes to channel the windstream to the rotor. In the preferred embodiment the rotor is a flow-through type with airfoil vanes.
A windmill comprising, a rotor having a vertical rotary axis mounted for rotation on an output shaft and a plurality of alike upright thrust vanes equally spaced apart circumferentially of said rotary axis, said thrust vanes each having an airfoil section with a nose, tail edge, leading face, and trailing lift face, and having its chord generally radial and its nose facing radially outward with respect to said rotary axis, whereby a rotor turning thrust is exerted on the lift face of those thrust vanes exposed to an incoming flow of air passing over the ...
