Paper Introduction:
Process--Energy has always been an important ingredient in the development of civilization. Large amounts of energy are necessary for sustaining industrial nations and bringing forward Third World countries. An adult human requires approximately 2500 food calories or about 100 watts of power, to sustain life (3:1). In the United States, the per capita consumption of all forms of energy is approximately 100 times this basic sustenance rate. For the entire world population, energy consumption is about 15 times the basis rate (3:1). A number of questions continue to arise. Is enough energy available? How long will the energy supply last? When will new sources be required? What world events will disrupt the flow of raw energy material, and what countries will suffer? Clearly, an inexhaustible supply of energy is required. This inexhaustible supply of energy may be
