The impending scarcity of petroleum threatens the world’s fuel supply. Mankind can face this threat successfully with the help of biogenous methane, but the world is prevented from taking full advantage of this technology, because its practitioners ignore the basic tenet of science, namely that output of work is dependent on the energy available for doing that work. The current practice of using low calorie inputs like cattle dung, distillery effluent, municipal solid waste or sewerage, makes methane generation highly inefficient. By using feedstock having high calorific and nutritive value to microbes, the efficiency of methane generation can be increased by several orders of magnitude.
