llisions that cause leaks might create dangerous situations quickly," (Moore, 93). Finally, retrofitted propane vehicles are void of warranty by all manufacturers, (Moore, 93). Until LPG vehicles are made attractive to the consumer, they will never catch on; however, certainly a cost-effective LPG vehicle seems feasible.The next category of proven viable alternative fuels are alcohols, specifically methanol and ethanol both obtainable from petroleum and natural (biomass) sources, many domestic resources, fossil and renewable resources, natural gas, and coal, (Reed, 74). "Replacing gasoline with pure methanol or natural gas as fuels could cut ozone levels by as much as 40%," (O&GJ, 24). Methanol has certainly proved that it is a desirable fuel whose combustion products are much less harmful to the environment than those of gasoline. Methanol also has many other positive aspects of use both for the environment and for conversion of current vehicles to run with it as fuel. There have been many arguments against methanol; however, technology has rendered many of these arguments null. Methanol first does have the best potential for widespread use of all of the other fuels. A methanol powered vehicle is "fundamentally the same as a gasoline powered car," (Moore, 93). Fuel-flexable vehicles that automatically adjust to operate on alcohol fuels, gasoline, or combinations of both are excellent choices for methanol fuel use. These type of vehicles are excellent since they allow a consumer to still use gasoline if areas of the country are lacking in methanol distribution systems. These type of vehicles have already been tested, as have many of the others mentioned, in California where 1000 are currently in use, (Reed, 74). Ford, Chevrolet, and Volkswagen have been the leaders in fuel-flexable vehicles in the U.S., and Brazil which once fueled its vehicles primarily with ethanol, (Moore, 93). Methanol also has a 100% octane rating and results in lo...
