http://finance.yahoo.com/q/pr?s=WPRT This is a Canadian company to watch. They are making nat-gas fueled engines and kits. Not profitable at the moment but Nat Gas is abnormally cheap - and amazingly so when compared to oil. A number of Congressmen are looking at the Pickens Plan again. In addition, Mexico may face disaster as their main oil field is failing at a astounding rate. Electric cars will be in our future, no doubt, but I believe we will need a bridge adaptation to get us there. Events are unfolding too rapidly to feel very comfortable.
