Finally I will briefly touch on turbine cars / engines. They are of course not alternative fuels, but can run on them more efficiently than any conventional ICE. Although most of the work on alternative car engine technologies has concentrated on electric vehicles, run by either fuel cells or batteries, another option deserving of a hard look is the gas turbine engine. Compared with the ICE, gas turbine engines weigh less, are longer-lasting, and break down less frequently. The gas turbine engine excels in terms of emissions; it is the only automotive engine technology to have met the most stringent limits tentatively set by the Environmental Protection Agency. The gas turbine vehicle also has some clear benefits over batteries and fuel cells. They can burn a variety of fuels and are compact sources of power, capable of producing 3-4 kilowatts per kilogram, versus less than 1.5 kilowatts per kilogram from a fuel cell and 0.5-1.0 kilowatts per kilogram from a battery system of a size sufficient to provide an acceptable range, (Wilson, 55).…
