A wind driven engine comprising a base, a housing which is rotatably mounted on the base, and two vertical rotors which are rotatably mounted in the housing and which are substantially enclosed by the housing. The blades of the vertical rotors overlap. An air diverter is centrally mounted inside the housing and in front of the rotors so as to divert air entering the housing onto the blades of the rotors which are adjacent the sides of the housing. The air diversion results in contradirectional rotation of the rotors, i.e., one rotor rotates clockwise and the remaining rotor rotates counterclockwise. An air vent is centrally placed in the housing above the air diverter to evacuate air from behind the air diverter. The vent is enclosed by an air shield which aids the evacuation of air through the vent. The contradirectionally rotating rotors are mechanically joined to an energy receiving system so as to be substantially self-timing and torque-free.

In a wind driven engine having: (a) a base; (b) a housing rotatably mounted on said base, said housing including a front inlet opening, a rear outlet opening, and at least two sides; (c) a first and second vertical rotor rotatably mounted in said housing and having a plurality of overlapping blades; (d) a wedge-shaped air diverter approximately centrally mounted inside said housing and forward of said first and second vertical rotors so that the flow of air which enters said housing is diverted onto the blades of said rotors which are adjacent the sides of said housing thereby rotating one of said rotors clockwise and the remaining rotor counterclockwise; (e) a vent in said housing which is centrally located over said air diverter; and (f) means for mechanically joining said clockwise rotating rotor and said counterclockwise rotating rotor to an energy receiving system; said joining means comprising: (g) a first hollow shaft rotatably mounted on said base, said hollow shaft being mechanically joined to said first vertical rotor; (h) a first gear means attached to an end of said hollow shaft; (i) a second shaft rotatably mounted above and extending through said hollow shaft and first gear means, said second shaft being mechanically joined to said second vertical rotor; (j) a second gear means attached to the end of said second shaft which extends through and is adjacent to said first gear means; and (k) means for mechanically joining said first and second gear means; the improvement comprising: a wedge-shaped air shield which covers said air vent, the apex of said air shield is closed and projects forward toward said inlet opening, and the rear of said shield is open at a point upstream of said rotors.
