Since the 30's the government and private concerns have been conspiring to keep oil as the main fuel derivitive. People have been murdered (it sounds so melodramtic, but true!) so their discoveries wouldn't be released. Only solution would be for some really wealthy individual (who hasn't joined the world bank/leaders club) decides to develope a patent privately. Even then I think he'd have only a slim chance of success. The more you have, the more you have to lose.
