Abstract
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 Analysis
Total Claims: 10
Claim 1
Independent Claim
124 words
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.
Claim 2
Dependent Claim
124 words
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.
Claim 3
Dependent Claim
82 words
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.
Claim 4
Dependent Claim
38 words
