Book excerpt: Dwindling petroleum supplies and growing environmental concerns are significantly impacting the cost of petro-fuel and its infrastructure. The search for alternative fuel sources has led to ethanol, a gasoline substitute that is already in the marketplace as Gasohol and E-85. But large-scale production of corn-based ethanol is controversial as it threatens the world’s food supply. There are alternatives, however: Brazil uses sugar cane, which is up to six times more productive in energy conversion. After the energy crisis of the 1970s, there was a lot of misinformation about the cost of individual ethanol production. In order to achieve energy independence from gasoline, ethanol lends itself to small-scale production, and especially to cooperative ventures in rural communities, often using “waste” feedstock. Alcohol Fuel is a practical, grassroots book that will give readers all the information they need, covering every aspect of making and using ethanol for fuel, including: *Permitting and planning *Budgeting and setup *Sourcing feedstocks *Finding and building distillation equipment *Storage and safety *Practical applications for converting motor vehicles, farm equipment, and space-heating systems The practical, user-friendly information on basic equipment needs, fermentation recipes, and distillation designs will be of interest to readers looking for information, as well as to those ready to make the switch.
