just a thought, but what if you added a sort of a funnel to the windward side of the box that holds the belt? Could that allow a single windbelt to get more power out of less wind? Of course that would also make it more susceptible being to torn apart by a strong wind, speaking of which, has anyone thought of some sort of safety mechanism that would keep it from coming apart like galloping gertie? p.s. has anyone thought about the dynamics of the belt itself? Does a wider belt vibrate more? How about length, is longer better, or do you eventually reach a point where adding length has a nominal effect on the power generation? What about power storage? Couldn't you have it charge a battery, like solar cells do, and then use some sort of power inversion out of that? And by what method is the magnet attached to the belt? What about guitar pickups? I mean a single metallic wire as the belt and the box around it containing some sort of magnet/coil setup. Is that too inefficient, or could something like that be done? Because that might be able to withstand greater wind forces, although a cylindrical belt wouldn't work as well as a flat one.... I think that's all for now. Sorry to ask so many questions, but this idea really interested me.
