Claim:
A windpower generator apparatus for use on a roof, the roof having a ridge with sides sloping downwardly therefrom, the windpower generator apparatus comprising: a rotor having a horizontal axis of rotation; and a frame suitable for placement on the ridge of the roof, said frame having a set of deflectors suitable for positioning on the sloping of the sides of the roof, said set of deflectors adapted to focus a flow of air toward said rotor, each of the deflectors having a pair of sidewalls and an upper wall and a lower wall, all four of the walls of each deflector defining a tunnel narrowing from an outer end thereof toward an end adjacent said rotor, all four of the walls of each deflector defining a square profile at said outer end and a rounded profile at said end adjacent said rotor, all four of the walls of each deflector being shaped progressively between said square profile to said rounded profile, said frame and said set of deflectors affixed to a structure adapted to the sloping of the sides of the roof so as to maintain a same ratio between an opening defined by all four of the walls of each deflector of said outer end and an opening defined by all four of the walls of each deflector adjacent said rotor, said structure having two pairs of arms, wherein each arm having a section with an inclination conforming to the sloping of the sides of the roof and another section extending upwardly therefrom, said structure having two connecting plates, wherein each connecting plate is affixed to the another sections of each of the pairs of arms, each of the another sections of said pairs of arms affixed within a slot formed in said connecting plate, said structure having a first part and a second part, said first part extending over ends of the lower walls adjacent said rotor, said second part extending over ends of the upper walls adjacent said rotor.
