ABSTRACT:
A wind powered apparatus which includes an external wind shielding shroud supported for rotation about a vertical axis; a rotor mounted for rotation about the same axis as the shroud and disposed partially within the shroud; and a stabilizer vane secured to the shroud on the outer side thereof. The shroud includes two halves, each of conical configuration, with the halves oriented in base-abutting relation to each other. Each shroud half includes a plurality of generally triangularly shaped, overlapping vanes having air escape spaces provided between the overlapped edges thereof. The rotor includes a plurality of circumferentially spaced blades, each oriented in a plane containing the axes of rotation of the shroud and rotor, and each defining an opening between its radially inner edge and the axes of rotation of the shroud and rotor.
