How Wind Power is Saving Millions During Polar Vortex

[Hestia]

6. I went to a Sustainability Conference a couple of years ago and found

out that our state is not conducive to wind energy - I think the dude said that the turbine would have to be built 200 feet minimum to capture wind for wind output of the turbines. Not cost effective at all.

When Discovery Science aired actual science shows, Eco Tech was one of their best shows. Instead of of blade turbines, this guy built tubes that laid horizontal on the tops of buildings, Chicago specifically, and wind generated all the time with his tubes because of the air flow and bats & birds were not being killed because of the design plus the tubes were more economical feasible.

Why not something like that for new turbines rather than the expensive pole & blades where doable?
