This is a fantastic and simple idea, Kai!  Would probably still function as a fresh air ventilator, too.  The greatest minds are those that are open to possibilities and the sharing of ideas.

That in itself could rob generating power. (Not to mention the threat of the blade assembly breaking up and send chunks flying in high winds) So what may be the answer?> Look at the roofs of older buildings, especially industrial buildings. What do they have?> Turbine ventilators.> Pre-built, factory balanced, wind-driven turbines. Time tested for the elements and efficient.> Most have a vertical shaft (bingo!) a brass upper bearing and lower ball bearings. A 24 inch model ($200 new) is rated to move 2300cfm at 4 mph. So it spins at low wind speeds.> Attach alternator "A" to turbine "B", add wind and you've got electricty. (Ok, maybe not THAT easy, but doable with some ingenuity
