There was a big story on Dateline about ethanol...Brazil has already done it. They are completely self sufficient for their fuel needs. They make theirs out of sugar cane. The experts on Dateline said "big oil" is the only thing keeping it from REALLY getting kicked off here, but it's still coming...soon! 85 to 90 percent of vehicles sold in Brazil run on ethanol. You can even buy 100% ethanol in Brazil...they'd never sell that here 'cuz it's basically moonshine. They said if we set up refineries next to places like orange juice factories (ethanol can be made from orange peels and waste too) We would have such a surplus we'd be paying about 70 cents a gallon! They went on to say if we, as a country, pursued the ethanol technologies more aggressively we could be independant of foreign oil in FIVE years! The car companies are already doing it, it's just that MOST of the flex fuel vehicles are sold in other countries. It doesn't even cost the auto makers any more to make flex engines. I think a few vaves or gaskets are different because ethanol burns hotter and faster (a little less MPG) But on Dateline they said it actually increases your horsepower a little.Like I said it's pretty much just moonshine and the "Duke boys" used to burn "shine" in the General Lee right?!...Yeeeeehaaaaaaw!:lol:
