This paper explains that, to reduce America's dependence on foreign oil, it is necessary to phase out the conventional internal combustion engine (ICE) gasoline engine; however, for now, gasoline must continue to be a widely used fuel in order to keep the gasoline industry of America strong. The author points out that, as oil prices continue to rise, hybrid automobiles (gas engine with electric motors complimenting them) seem to be the near-term solution. The paper relates that the next viable solution to the pollution problem posed by ICE is hydrogen (H2) and fuel cell technology; a fuel cell combines H2 and oxygen to create power through the by-product of this chemical reaction without the pollution problem.
From the Paper:
"Another way to save fuel with out using new engine technology is described in Wald's work on pg.1-2, and was developed by the EPA. It uses current engines to pressurize a hydraulic tank to 5,00psi.. The built up pressure is then used to drive a turbine, which drives the wheels. Lab tests show a 60-70% gain in fuel efficiency. This technology is currently in use by John M. Hewitt of Memphis Tennessee. John is using a Chevy s-10 pickup engine (less than 100hp) to pressurize the tank and is getting better than 100mpg. Ford has said they are working with the EPA to make a SUV with this technology."
