Yes, I am aware of the extreme torsional scenarios -- did mechanical/flu-mech course in engineering -- thanks for the video. In case of Sheerwind's funnelling technology a normal windy day could also become a challenge though.
There are severe economic issues with paying for a giant funnel using the wind it generates.
No one has discussed if you basically turn the funnels into cell tower antennas then you piggy back onto the existing cell phone ecosystem.
Or piggy back onto land mobile radio trunking system ecosystem, or legacy broadcast media ecosystem.
You're building a giant horn antenna. Why not make it conductive and collect some "free" cash?
