There is a lot of talk about big projects to gather energy from wind. I have two ideas I dont see used that I was wondering about. 1. Using large stretches of canvas to redirect wind from a large cross sectional area to a smaller outlet, like some kind of wind nozzle. It would also form a low pressure area on the one side of the canvas which may also be utilized. 2. having multiple stages along a rotor or steel cable. Maybe with more blades on the rotor a larger generator could be used. Just a couple ideas here, I am interested in what you think of these ideas, any other ideas, and where I could find more simulated or real models of some windfarm systems.
