Just when I thought we had heard it all. This underground windmill is 280% more efficient than current models. They state that birds and bats have nothing to fear from this new technology.www.sheerwinds.com

Wouldn't the bats try to roost in the dark, cave-like tunnels, and then get sucked into the turbines and killed when the wind blows?

In the gap between the two horns the wind would create a vortex that would create a pressure gradient from the top of the second horn and the feed throat of the main horn. This pressure gradient would start the movement of air into the feed tube to the generator.

I swear - I don't know how you guys keep coming up with this stuff...
This can't be very efficient... Since air is like water and electricity - it takes the least resistive path...
There is a really big difference in the mechanical force generated by 30-60 foot radius propeller blades and a 60 foot cone.
Has anyone seen any working prototypes?
I am leary of this - but trying to keep an open mind - ya never know, they may actually be able to pull that rabbit out of that little itty bitty hat..
