Catch all the wind on the side of the building and lead it to
your generator ([edited] with turbine inside pipe).
Perhaps some external energy would be needed to be put
in, so that the wind blow would be directed to this location.

At least the last two appear to employ this concept. [moomintroll, Mar 26 2010]

Well, yes ish. Clearly, if you have a large flat wall and the
wind is hitting it obliquely, it will tend to direct the wind
toward one side, where you could site a turbine. Or a
slopey-sided building could direct ground-level wind
upward to a rooftop generator. But it doesn't sound very
promising to me. |

Perhaps an alternative would be to adapt high-rise
buildings to funnel wind. Imagine a cube (this cube being
the top 10 stories of a big building). Now imagine making
the four walls of the cube convex (ie, pinched-in), so as to
present a square funnel to wind coming from every
direction. Then put some kind of turbinical thing in the
middle. Maybe. |

It seems unnecessarily dangerous to put 100-foot spinning propellers in the middle of a city. |

That's got to be worth a bun, then. |
|
| |
How about mounting the whole building on a turntable, and profiling the sides so one half of each side is concave and the other convex? Then the building itself would spin. |

I don't have a link handy but this is being somewhat baked already. There was one recently in the paper, a CSU project where 4 small turbines on the side of a water tower were using the tower itself to funnel the air into the fans, allowing them to be much smaller. There are also some rooftop style ones, using the broad side of the sloped roof as a ramp for the air to blast into the turbines. These areas are higher pressure and higher speed, so small turbines do well. |

Something like auto mcdonogh said was what I
meant. The wind goes into a pipe and is lead to
one
point where the turbines are located (internally),
and
then up a chimney and out above the roof. |
|
| |
Improvement: Gather wind on roof toward pipe
exit,
and create a vacuum Bernoulli effect making the
pressure diff on the turbine even greater. |
|
| |
No moving parts, real easy and probably low cost
to
make. Call for Do It Yourselfers or handypeople!
Wanna try? |

I already gave you a [+] oc(Oo. |

This wind capture idea leads into a single pipe. Like a
wind tower. Your idea is more of putting the
centrifugal turbine along the edge. |
|
| |
In addition to generating power, could it also play
subsonic pan-pipes? |
