I would like to see this technology take off as well. I mean, can you imagine that if you could generate enough current from them how useful that would be in something like a car when its going down the highway? To say nothing of how easy it would be to implement as a alternate energy source to wind turbines. You could stretch those things between power poles or something like that and not have to use land resources as you would with solar or wind turbines.
Ive said it before and I'll say it again, there is no one resource, renewable or not, that is going to replace our current resources. We are just going to have to buckle down and start building the infrastructure to use several alternatives, tailored to the region. Solar for areas like Arizona, Nevada, etc. Wind for the plains, and so on.
