In an age when the supply of gasoline to feed this modern American society has become both more expensive and more scarce questions are being pondered. Inquires like, How can a modern society scale back its dependence on gasoline as a motive source?' Are there genuine alternative power sources?' Are they the answer to a growing crisis?' Recent announcements of hybrids like those from Honda, Toyota, and Ford have really brought attention to this issue. Hybrids that use both gasoline engines and electric motors. Really, though, alternative power sources have been around for as long as the automobile has been. The battle between and among the steam car, the electric and the gas car was fought out in the first couple of decades of the twentieth century. This book explores the ins and outs of that battle. A struggle from which the gasoline car emerged completely victorious. To such an extent that steam cars and electric cars virtually disappeared from the scene for many decades. We will look over all three alternatives, exploring their advantages and disadvantages. We will also look over the obstacles to the steamers and the electrics. Barriers that still exist to a certain extent. Handicaps that caused their disappearance in the first place.
