Natural Gas is plentyfull and its power technology is not new. In Europe, where gasoline is always expensive, all auto manufacturers, including Ford and Opel(GM) have been manufacturing almost all of their trucks and SUVs with dual tanks for ever. One for Gasoline and one for GPL ( Liquid propane like for your grill) You just turn a switch and go from gasoline to natural gas which is much cheaper. The technology is well develloped and can be improved if the will and demand were there. In my city and many American cities, they allready use it to power the buses. It burns very clean with no pollution and is very efficient. We have huge reserves of it and so, many areas of the world. Russia has the largest reserves and has been suppling Europe for years. As an interum solution, Natural gas should be one of the answers to independence from Arab oil. I suspect that our politicians prefer to make deals with the ethanol lobby and raise our food prices.Corn ethanol is a very poor substitute.
