a weekly question for alternative energy promoter Scott Sklar to answer. This week, Sklar answers a looks at why butanol, with its high energy content, isn't more prevalent on the biofuel scene. Sklar responds that it is true that butanol's BTU content rivals that of gasoline and that it is less evaporative than either ethanol or gasoline. But, with low yields from biomass and little effort put into promoting the fuel, the market for butanol as a fuel remains quite tiny. Also, most of the butanol used today is made from petroleum, although it has been made since the early 1900s from corn and molasses.
