It is a mad cool image. I would like to promote your graphic with a story series I am doing online called Hub City Blues. The Tornado Trapping System is an impressive looking image which deserves story to be made from it. You can read the lead in chapters here: Tales of Hub City: [link]
mind you its not just the wind that the machine captures but all that lightning generated creates a great deal of energy as well. I can imagine how this might power some sort of plasma weapon when used as a planetary defense. Using the earths weather to power weapons is a brilliant idea. Oh and it is a nice picture as well.
the idea of tornado traps is to create them, and use the energy to power turbines. the plant would work by "...pulling hot, humid, low air into itself and creating a vortex - approximately the way a tornado works, this air makes a major temperature difference between the engine and the atmosphere above, making a vortex extending into the atmosphere." (Scientists Developing Tornado Power Plant, Jonathan Bolding, [link]) (the annotations are probably wrong, as I was never any good at those...) Your design looks far, far more epic, though <3
