Makes the question come to mind: If an feasible alternative to fossil fuels is eventually found, what will the new technology's impact be on the oil-rich but unstable countrires? Presumably there is a heavy flow of money coming in to those countries now in return for the oil; what will happen when that oil is no longer needed and the flow of money stops?

I know. Wishful thinking and very premature. However, will the day eventually come when the 'developed' world goes on to new, much cleaner fuels while the 'undeveloped' countries continue belching unchecked and unmonitored contaminents into the air? That oil will last a LONG time if it is used only regionally.
