Abstract

A wind powered turbine (30) has a conduit (34). A middle conduit portion (46) is located between inlet and outlet conduit portions (44, 48), having a main inlet (54) and outlet (56) of the conduit (34), respectively. A rotor (80) having a shaft (82) with blades (88) extending therefrom is located in the middle conduit portion (46). The blades (88) are located completely within the middle conduit portion (46). Preferably, a splitter (60) is located in the inlet conduit portion (44) to provide upper and lower sub-tunnels (61, 62) that both feed into the middle conduit portion (46). Upper and lower interior walls (91, 92) of the middle conduit portion (46) have substantially circular plane shapes that are substantially centered at the rotational axis (84) of the shaft (82). Clearance gaps (93, 94) are located between the blades (88) and the upper and lower interior walls (91, 92), respectively.
