Stackable Wind Funnel

The general idea for a stackable wind funnel is that it is able to concentrate windflow to a smaller area, thus reducing the required blade size of any turbine that would want to generate power from it. One nice thing about a stackable design is that you can continually add more wind funnels to the stack, increasing the wind gathering surface area. Intuatively, this could increase the power generated by the turbine (this claim is yet to be tested scientifically).

This design is for a vertical stack, with wind being concentrated at the top or bottom of the stack. (depending on the orientation). I prefer the orientation where the concentration goes toward the top. I like to think that this configuration can take advantage of any rising warm air that is produced by the enclosed structure. Perhaps it is able to produce power with no wind on a bright sunny day.

Designer's Side Comment:
I've been working on this for a while now. I think it's finally at a stage where it can easily be
