Scientists may have found a new source of fuel that won't dry up the earth's resources. US scientists found out that fructose, sugar found in fruit such as apples and oranges, can be converted into a new type of low carbon fuel for cars.

On the other hand, a British report says that all types of waste products, including plastic bags, can be used to make biodiesel fuel. Critics say, however, that biofuel is not the way to go. Farmers who realize how much they can make from making fuel switch to its production, neglecting food and driving up prices in the process.

Even so, it's not easy to ignore what the University of Wisconsin-Madison discovered. Simple sugar fructose can actually be turned into fuel called dimethylfuran, which is more efficient than ethanol - it can store 40% more energy and doesn't evaporate as easy.

Sounds good? Hitting two birds in one stone can't get any better, if we can get both food and fuel from fruits alone. Of course, there's always a catch. It would cost 10 times more to set up a production facility that churns out fuel from sugar than building biofuel refineries. Oil companies will also no doubt complain against what seems to threaten their market.

Right now, we can't expect dimethylfuran for commercial use. In the near future, maybe. The time our cars are running sugar, those will be the good days.
