No Foolin' - These Are Some Real Unusual Fuels

 

In the movie "Back to the Future," scientist Emmett "Doc" Brown invents a time-traveling car. By the end of the film, the car is using a "Mr. Fusion" power generator that runs on ordinary household waste. As it turns out, Hollywood's idea for future fuels wasn't too far off. In real life, researchers are working on all kinds of weird fuel sources for cars in an effort to curb the numerous side effects of our dependence on petroleum-based fossil fuels. It might sound crazy, but companies and researchers are actually working on making fuel for cars, trucks, and even airplanes from some of these sources:

• Sawdust, wood chips and nuts
• Used diapers
• Bad batches of chocolate
• Cow waste
• Coffee grounds
• Used polystyrene cups
• Turkey guts
