Abstract

A high rise building is provided including upstanding peripheral wall portions and at least one of the peripheral wall portions includes an upstanding air flow passage extending therealong. Horizontally outwardly projecting and downwardly opening hollow snout-like shrouds define air inlets opening outwardly and downwardly along the one upstanding peripheral wall portion and inwardly into the air flow passage at points spaced vertically therealong. A rotary turbine including an inlet and outlet is supported from an upper portion of the building and the upper end portion of the air flow passage is communicated with the inlet of the turbine. The turbine includes a rotary output shaft and a generator is driven from the rotary output shaft of the turbine for generating electrical current.

Claims

1. In combination with a high rise building of the type including upstanding peripheral side walls, at least one of said side walls including horizontally spaced apart vertical tiers of vertically spaced windows, at least one duct means having a vertical outer wall, said duct means extending along, supported from and projecting outwardly of said one side wall between a pair of adjacent tiers of windows, said outer wall including vertically spaced horizontally outwardly projecting and downwardly opening snout-shaped shrouds opening in upwardly inclined directions into said duct means, and rotary turbine means supported from an upper portion of said building including an air inlet and an air outlet, the upper end portion of said duct means being communicated with said rotary turbine means inlet.

2. The combination of claim 1 including additional duct means, corresponding to the first mentioned duct means supported from and projecting outwardly of said one side wall and extending along the remote sides of said tiers of vertically spaced windows, said additional duct means also including vertically spaced horizontally outwardly projecting and downwardly opening snout-shaped shrouds opening in upwardly inclined directions into said additional duct means, the upper ends of said additional duct means also being communicated with said rotary turbine means inlet.

3. The combination of claim 1 wherein said rotary turbine means includes a rotary output shaft, generator means for generating electrical current and including a rotary input shaft, drive means drivingly coupling said output shaft to said input shaft.

4. The combination of claim 3 wherein said drive means includes endless flexible drive belt means operably connecting said output shaft to said input shaft.

5. The combination of claim 1 wherein said rotary turbine means includes a cross flow rotary turbine.

6. The combination of claim 5 wherein said rotary turbine includes generally radial blades spaced about and along the axis of rotation of said turbine.

7. The combination of claim 6 wherein said blades are generally V-shaped in transverse cross section with the apex portions thereof facing in the direction of rotation of said rotary turbine.

8. The combination of claim 1 wherein said shrouds include outwardly concave radiused upper outer surfaces opening upwardly and outwardly from said wall portion, whereby wind incident thereon will be smoothly upwardly diverted along said duct means toward downwardly opening shrouds disposed thereabove.

9. The combination of claim 1 wherein said duct means includes an outer transparent wall and inner radiant heat absorbtive inner wall means.
