Harnessing natural energy by covering an earth's formation such as a canyon (10) with a canopy (21), thus forming a prevailing wind funnelling duct (20) which converges from a lower opening (22) to a higher, smaller opening feeding the resulting airstream to an electrical power generating station (70) having wind turbine driven generators (77). The canopy has transparent, heat insulating panels (28) to provide and contain solar heating of channeled air to create or enhance the wind funnelling effect. |
