ABSTRACT:
The present invention is directed to improved apparatus for incorporation in buildings and structures particularly useful in converting the energy of the wind to other usable energy forms. A rotor comprising a plurality of successively longer wind wheels interconnected along a common axis of rotation is disclosed. More particularly, an improved wind wheel construction useful in wind-driven rotors comprising a plurality of wind wheels is disclosed. Maximum power is developed by a wind wheel comprising some vanes located substantially parallel to the axis of rotation for maximum power development and other vanes located substantially perpendicular to the axis of rotation for both power development and stress reduction. A rotor comprising a plurality of wind wheels characterized by rotationally misaligned vanes reduces fluctuations in the rotational velocity of the rotor. Further, apparatus useful in providing both improved structural strength and support for exterior protective glazing is disclosed.
