Default Idea for vertical axis attic heat powered

I was thinking about this one again yesterday. I was working in the hills and saw 2 large horizontal turbines, maybe 3 meters each just above the tree tops, not spinning! What a waste. They should have been much taller. I noticed the neighbor's whirlybird attic vents were moving right along. I know it takes a lot more power to turn big propellers especially against an electrical load, but perhaps you could generate some micro wind from your attic heat and or the wind. Just throwing it out there, not sure the best way to implement it but there's no shortage of attic heat where i live.
