there's more and more discussion about whether or not this is a buyable solution to the energy problemscould the country morph to natural gas? is this something that could realistically happen? >> realistically we're a ways from it. right now natural gas in heating and cooling our homes. some 18-wheeler trucks already are using natural gas as the fluid that runs them, for example they have a choice between diesel and natural gas. some of them use natural gas, even some cars in this country believe it or not run on natural gas but there's only one car that's made and marketed in this car that runs on natural gas, a honda. look at europe right now, every major automaker, including the american automakers make natural gas operated cars, so we're a ways from actually having them come here and build a car for americans, because americans aren't demanding that car just yet. >> paying $3.65 for a gallon to i guess fill up a natural gas car, what are we looking at? >> there's a big difference here and right now, the difference is so significant, boone was telling me he drives one of these cars,
