An energy generation apparatus 100 comprises a casing 104 containing a least one duct 106 to have fluid channelled therethrough and a region of reduced cross-section compared with other duct regions. At least one rotor 108 is located within the duct to be rotated by fluid passing through the duct to generate power therefrom. At least one driven fan 110 is arranged to influence movement of the fluid through the duct such that the driven fan increases the velocity of the fluid at the rotor to allegedly increase overall output. There may be multiple entry fans 110 and/or multiple exit fans. There may be main 108 and auxiliary 109 turbine rotors supplied by internal ducting 117, angular momentum inducing inlet deflectors or box or grid wind straighteners 118. The assembly may be a roof mounted wind turbine. |
