but i'm curious to know from you, mr. eisenberg and mr. durbin, as these estimates of the vast resource change how do your projections on the economic impact that will have been job creation and manufacturing resurgence, how does that change, in your estimates, and how closely are you monitoring that as we look at what the vast reserves actually provide? >> our policy and frankly, the will of the manufactures that is before is not a stable, secure, and consistent supply of natural gas. because we use it not only for electricity but also to feedstock for the many things we do. that's a lot of what i do for a living. we need to keep an eye on the policies that are coming out of washington, and places like that to make sure that manufactures can still continue to do what they do. so obviously, yeah the supply matters significantly.
