Diagram of a mitochondrion, like those used in the mitochondria biofuel cell
In Back to the Future, the Mr. Fusion cold fusion device could produce electricity from food scraps. Well, cold fusion is still some ways off (depending on who you talk to), but powering electronics with food may not be. Shelley Minteer, a Professor of Chemistry at Saint Louis University in Missouri, announced this Wednesday the development of a biofuel cell that could be powered by sugars or fats like those found in soda pop or vegetable oil. The device incorporates mitochondria, which are found within the cells of our own bodies, where they serve to produce energy from ingested calories. Are you listening, Doc Brown?
