In a scientific milieu as ours, nothing can be taken for granted. If the reports in a major technology journal, Science, are to be believed, biofuels are doing more harm than good to the environment due to higher emission of greenhouse gases than petroleum fuels! As a remedy for this problem Coskata Ethanol Production Cycle deserves nothing short of a standing ovation for its breakthrough approach.
Coskata claims it is possible to make Ethanol from any carbon rich source, even your old tires, for less than $1.00 per gallon. If that price is correct, it implies half the price of producing traditional gasoline, and well below any other biofuels hitherto! The step by step procedure is given in this self-explanatory diagram of the system. If this were to materialize, the world shall witness some pioneering efforts in the area of biofuel synthesis.
