Abstract
A wind turbine that is mounted on a corner of a building and has a shaft that extends upward and outward from the corner, where the turbine blades are located, and the resulting rotation of the shaft is used for some power consumption purpose in our outside the building.
Claims11
A wind turbine system comprising:
- a shaft mounted on a corner of a building, the shaft obtusely skewed away from a first surface, a second surface, and a third surface of the building, said first, second, and third surfaces being proximate said shaft;
- and
- a plurality of blades coupled to the shaft such that said blades do not interfere with any of said first second and third surfaces, said blades causing said shaft to rotate upon the impingement of air.
A wind turbine system on a building, the building having a corner defining a first edge, a second edge, and a third edge, the turbine comprising:
- a shaft mounted on the corner of a building, the shaft pointed away from the corner obtusely relative to said first, second, and third building edges;
- a first blade;
- a second blade;
- a third blade;
- each of the first, second, and third blades having a leading edge, a trailing edge, a concave side and a convex side;
- and
- the first, second, and third blades, upon impingement of air upon the concave side of each of said first, second, and third blades, causing the blades to rotate the shaft.

A wind turbine for a building comprising:
- a shaft extending down and into a corner of said building and extending upward and away from the corner of the building;
- a plurality of blades mounted on the shaft outside the building;
- and
- a power-converting mechanism located inside the building, the mechanism converting the energy in said rotating shaft into some other useful form.
