Not to derail the topic but it does amaze me how much research and development goes into keeping fossil fuel engines alive and practical. Im no hippy but if that much research went into alternative fuels we'd probably all be driving 500 hp trucks that run on our own farts.
You show some ignorance of a few topics with this post. While I don't disagree that we should be researching different forms of energy, there are reasons we stick largely to so-called "fossil fuels".
1) Gasoline and diesel are the most viable fuels we have at the moment. They are relatively stable at normal temps, when in liquid form. That means they can be transported and handled by the average person relatively easily and safely. You don't need special gear like you would for a radioactive material, nor special training and equipment like you do for CNG or LPG fuels.
2) Gas and diesel have the highest BTU ratings of currently viable fuels. More BTU means more energy, means you go farther on a given amount. People like bang for buck.
3) The infrastructure, for nearly a century, has been geared almost 100% towards gasoline/diesel engines. Our training, both of repair technicians and fuel handlers, our fuel distribution, the storage facilities, the refineries, all of it. For a long time there were few places that offered "flex fuel (E85)" or compressed fuels. At the time I took Ford's training on CNG and LPG vehicles the on-line course had a thing that said these fuels were barely available outside a few locations the south west.
4) We don't actually know that crude oil comes from ancient biomatter. And the evidence that it might not is growing. There is also a growing body of evidence that suggests "fossil fuels" are not nearly as non-renewable as we have been lead to believe. Wells that the drillers thought were empty have been revisited and found full again in a space of just a few years.
