Renewable, ethanol based fuel sounds promising, like the do in Brazil
That is if the greedy war mongers and their Arab business partners don't prevent it from happening here in the USA. If Brazil can kick the oil habit , there is no excuse for the USA not to be able to as well - wait maybe not.

Three decades after the first oil shock rocked its economy, Brazil has nearly shaken its dependence on foreign oil. More vulnerable than even the United States when the 1973 Middle East oil embargo sent gas prices spiraling soaring, Brazil vowed to kick its import habit.
