As the end of the era of abundant natural petroleum oils approaches, the United States finds itself heavily committed to a way of life based on cheap liquid hydrocarbon fuels. Whether such fuels will be available at any price in adequate quantities in the future, is the question today. Professor Vietor shows that it was also a serious question for some years after World War II, and that the United States carried a long way towards definitive demonstration a program for the development of high-volume synthetic liquid fuels production techniques. What that program accomplished; how the interests, public and private, who were responsible for the American fuel supply reacted to it; and why it was shelved for 25 years are among the points Vietor covers. The reader is left to weigh for himself the several reasons why this program was sidetracked, but he can hardly fail to conclude that where such fundamental matters as energy policy are concerned, American planning has been distressingly short range.
