ABSTRACT:
A wind-driven power generator comprises a substantially horizontal roof including upper and lower roof members each having a peripheral edge and a contoured pressure reducing surface. The roof members are disposed in a spaced-apart relationship with the pressure reducing surfaces facing each other and defining an air space therebetween. The distance between the pressure reducing surfaces varies from a maximum spacing at the peripheral edges of the roof members to a minimum spacing at an intermediate location of the roof members. The power generator further includes a vertical suction pipe having an upper end connected to the lower roof member in flow communication with the air space at the intermediate location of the lower roof member. The lower end of the suction pipe extends downwardly from the lower roof member. An impeller is disposed in the suction pipe at the lower end thereof and rotates when air flows horizontally through the air space. In accordance with Bernoulli effect, the increase in speed of the horizontal air flow at the intermediate location creates a pressure reduction in the air space at the upper end of the suction pipe and draws air up through the suction pipe to rotate the impeller. The impeller preferably is connected to an electrical generator that generates electricity when the impeller rotates.
