If we want to get off oil then maybe we should get off oil. Why can't we build a solar powered electric car, a steam car, a chemical reaction engine, nitrogen, a hybrid that uses anything BUT oil? Yeah its not easy... and there are people against you but it can be done. It sure beats sitting in a forum all day complaining about how nobody does anything and nothing can be done.
Just for kicks maybe we should see how much money and time and resources it would take to make something like that.
Car without oil? Those things are not a thing of the future, the technology already exist. All you need from now on is just money. And a strong determination that allows you to only fuel up your car where you live .. for now.
