|11. Alcohol fuel as a
The growing demand for gasoline and the potential shortage of oil was one reason alcohol fuel was seen as a possible replacement. Another important reasons was that it would keep cars on the road if there were an emergency (which made Detroit happy) and that it would create a new market for agricultural products (which made farmers happy).
Repeal of the Internal revenue tax on alcohol was the first step in making alcohol fuel competitive. The $2.08 federal tax on alcohol during the Civil War was meant to apply to beverage alcohol, not industrial uses such as fuel. The automobile industry was ceneterd in Detroit and representatives of the Detroit Board of Commerce attended legislative hearings to support removing the tax. Auto manufacturers told a Senate hearing that car manufacturers worried not so much [about] cost as ... supply. [i]
James S. Capen, who represented the Detroit Board of Commerce, said: Alcohol can be produced from any old thing that has sugar or starch in it, and once given our American inventor a chance at a market as great as this, in a very short time he will have processes that will do away with any fear of scarcity of fuel. Capin said alcohol was preferable to gasoline because it was easier to make and harder to control than gasoline, and thus artificial shortages could not raise the price in the future. And alcohol was much safer than gasoline, as well as being absolutely clean and sanitary.
The Free Alcohol hearings in 1906 were the efforts made by American farm movements that would propose wider alcohol fuels use again in the 1930s and 1970s, with much the same arguments made by Capen.
In the 1930s, theFarm Chemurgy movement promoted industrial uses of all kinds of farm products. The movement was backed by Henry Ford and other conservative industry leaders from the Midwest but was not embraced as part of the New Deal. Although the alcohol blended Agrol brand failed economically, the research behind it proved crucial to production of synthetic rubber and other vital industries during World War II.
In the 1970s, Midwestern farmers again began advocating alcohol blends in gasoline, this time to fight pollution from leaded gasoline and to strech oil supplies in the wake of the Middle Eastern oil crisis.
The broad ranging competition between gasoline and alcohol fuels in the early and mid 20th century is not today as well known today as a similar competition between steam and electric automobiles with gasoline powered automobiles.[ii]Nevertheless, hundreds of magazine articles, reports, books and technical papers reflect that fact that alcohol fuel was widely acknowledged as technically feasible fuel and economically competitive if oil supplies should run short.[iii] By 1920, the consensus, Scientific American said, was a universal assumption that [ethyl] alcohol in some form will be a constituent of the motor fuel of the future. Alcohol met all possible technical objections, and although it was more expensive than gasoline, it was not prohibitively expensive in blends with gasoline. Every chemist knows [alcohol and gasoline] will mix, and every engineer knows [they] will drive an internal combustion engine.[iv]
