Thats wat i ve seen on CNN tonight, Brazilian and Americans are producing new form of fuel (new for us). I think they started this in 1970. This fuel is extratcted from Sugar canes. Here is an article from wikipedia:
In Brazil, ethanol fuel is produced from sugar cane which is a more efficient source of fermentable carbohydrates than corn as well as much easier to grow and process. Brazil has the largest sugarcane crop in the world, which, besides ethanol, also yields sugar, electricity, and industrial heating. Sugar cane growing requires little labor, and government tax and pricing policies have made ethanol production a very lucrative business for big farms. As a consequence, over the last 25 years sugarcane has become one of the main crops grown in the country.
