I've read in several places over the past week how diesel is pretty much useless because diesel powered cars cost more and diesel costs more than gas. Half brains, that's not the point!!! 1) Diesel powered cars require fewer trips to the pump and 2) gas will continue to go up and you're kidding yourself if you think $4/gallon is it. I have no doubt with the emerging market in play that gas stateside will one day rise to what are European levels today. Several years will go by fast. Something also needs to be done with American refineries churning out more diesel for Europe than for home in order to bring down the cost. In the grand scheme of things diesel is a major party of the energy solution; the less petrol we use as the world the better off all of us are. Ditto for our future.
