While greenies and their media flunkies continue to savage the gasoline-powered internal-combustion engine and rhapsodize about hybrids, hydrogen, electrics, natural gas, propane, nuclear, and God-knows-what-other panaceas, perhaps including bovine urine, there are no realistic, economically viable alternatives. None. Zero. Like it or not, as long as we remain dependent on the private automobile for transportation (roughly 80 percent of all movement in the nation is by car), we are harnessed to the IC gas engine.
