In an earlier comment, Dagon called for mass conversion to ethanol as a way of ending our dependence on oil. I mentioned that he hadn't said where all that ethanol would come from. Little did I know that it turns out we are barely started on using ethanol in this country and there is already an ethanol shortage! Sure we can grow more corn, but at the expense of what? Wheat? Soy beans? Do we really want to be forced to choose between energy and . . . food? Somehow I doubt that this is the long term solution we've been looking for.
