I love this idea. The problem with many wind turbine installations has been the NIMBY it fosters in local communities. The large turbines, destroy the view, make too much noise and cost too much. Those are the usual complaints. We have a major wind project held up along the cape cod coast for exactly these reasons.

Well what if commercial buildings incorporated the vertical designed turbine described below ? What if cites incorporated these units into there power systems (think electrical distribution poles), or into there signage throughout the city? What if billboard owners put these units on there billboards (especially the display units with leds)?

These seem much less obtrusive than other wind turbines, they can capture the wind from any direction, they are quieter than traditional. Yes, they produce less energy than many of the bigger units, but this is a volume game here. Hopefully with mass production would come lower per unit costs. Some Specs on the big selling unit;
